Conditions for constructing small organic fertilizer production line
What conditions do we need to build a small organic fertilizer production line? Small organic fertilizer production line can be a powder organic fertilizer production line, or can be a granular organic fertilizer production line.
The production lines of organic fertilizer with an annual output of less than 20000 tons are small organic fertilizer production lines. According to the planning of most customers, the small organic fertilizer production line has 5000 tons, 10000 tons, 15000 tons and 20000 tons.
Because the production line of powdery organic fertilizer is the component of the production line of granular organic fertilizer, we will use the granular organic fertilizer production line to elaborate the technology of small organic fertilizer production line today. The technology of fertilizer production line will be clear.
Process flow of granular organic fertilizer production line:
So, what conditions do we need to build a small organic fertilizer production line?
(1) The construction of small-scale organic fertilizer production line meets the requirements of environmental protection policy. Environmental protection is not only the desire of the people, but also the policy demand for environmental protection for the development of agriculture and animal husbandry;
(2) Raw material source, radius of raw material source, determine your plant location, site investment, transportation investment, etc;
(3) The types of raw materials, the specific equipment types used in each stage of the process, and the investment price of the equipment are affected;
(4) The production scale, the production capacity of small organic fertilizer production line from 3000 tons to 20000 tons determines the equipment capacity requirements, thus affecting the price;
(5) The recycling of resources mainly depends on a variety of agricultural pollution waste recycling methods, such as fuel and electricity raw materials, and biogas residue is used as organic fertilizer raw material;
(6) Other small organic fertilizer production line technology, can be used as feed.
(7) Site: the size of production site and investment of site scale shall be determined according to the planned production scale.
1. The pre fermentation and turning equipment mainly plays the role of composting and material turning, and is more suitable for microbial fermentation to store manure into fertilizer. The technology requires that the viscous storage manure can be effectively mixed with microbial preparation and straw powder. It can not only ferment fast, but also prevent the production of harmful odor gas in fermentation process, which meets the environmental protection requirements.
2. The special pulverizer for organic fertilizer is mainly used for better crushing and fermentation materials, which lays a solid foundation for the next scheme provider. When choosing organic fertilizer pulverizer, we must choose the suitable ones for their own use, and do not blindly. If selected, otherwise, the crushing effect will not be reached, but the normal operation of the next process will be affected.
3. Organic fertilizer mixer is used for mixing formula fertilizer, adding various substances, mixing evenly, and carrying out the next process.
4. The granulator of organic fertilizer mainly plays a role in granulation. The mixed material is uniformly fed into the granulator by conveyor for deep granulation. It can be made into various sizes and shapes according to the local market. There are many kinds of granulator styles and models, and the appropriate granulator can be selected according to the production and requirements of customers.
5. The dryer mainly acts as evaporation material moisture. Because of the large water content in the granulation process of fertilizer granulator, it can not meet the national requirements. The granulation can not be packed immediately, and the moisture should be dried by drying equipment. Evaporation to the state of national standards for the next process.
6. cooling machine. Because the temperature of the dried material is high, it can not be packed immediately, and the woven bag is easy to be burned. The temperature of material needs to be reduced to constant temperature quickly through cooler to carry out the next process.
7. The screen separator mainly plays a role of grading. Because of the granulator granulation rate, the difference of dryer and cooling opportunity, and the particle damage, it is necessary to distinguish the finished particles from the inferior products. After the next procedure, the defective products will be re comminuted and the granulation cycle work will be carried out.
8. Automatic packaging machine mainly plays the role of finished product particles, automatic.
In the process of making a series of special fertilizers, inorganic nutrients and minerals should be added according to different soil conditions and different crops. These minerals are concentrated in organic matter and trace elements, so that the fertilizer contains various nutrients needed for plant growth, such as nitrogen, Phosphorus, potassium, sodium, manganese, zinc, copper, etc.
According to the formula, nitrogen, phosphorus, potassium and fermentation material are mixed by computer and transferred to granulator for granulation. We mix organic and inorganic materials according to different series of products, and mix them well in blender. Assume that the proportion of organic materials is 12%, about 12 tons.
The production process should not be exposed to high temperature and other characteristics due to the poor formation conditions of bio fertilizer mainly composed of organic matter and cellulose and the viable bacterial population with the function of making fertilizer.
Disc granulation and drum granulation are not suitable for building materials, because these two technologies require fine grinding of raw materials, high moisture content of granulation, and generally the moisture content is about 30%, so the load is relatively large. There are different types of fertilizer granulators for your fertilizer granulation process.
For drying, the loss of effective bacteria is great, and the pelleting rate is low (about 60% – 70%), the dust is heavy, and the operating environment in the production process is poor.
Therefore, through the extrusion environment, the requirements of raw material crushing are low, the molding rate is high (more than 95%), the water content of formed particles is low, the drying load is low, the environment is dry, and the production of organic biological functions should be better. Can reduce the loss of effective bacteria, less dust and good working environment.
70 tons of organic fertilizer raw materials, using organic fertilizer special granulator. After granulation, the material is sent to the dryer by belt conveyor for drying. The particle size is 3.0-4.0 mm, and the granulation rate is more than 70%.
The recommended pelletizer is a new type of pelletizer for organic fertilizer.
(4) Drying (fertilizer dryer)
In the production process of biological fertilizer, not only does the moisture content of granules generally exceed the index after molding and need low-temperature drying, but also the moisture content of organic matter after fermentation is about 30% – 40%, and the granule after granulation is generally between 15% – 20%, which needs drying treatment, because the moisture content of fertilizer quality index is less than 14%.
The drying stage is an essential and important process in the production of biological fertilizer, which directly affects the yield, quality and energy consumption. It is very important to choose the type and specification of dryer and control the process conditions.
In order to avoid the death of effective living bacteria due to the high temperature in the drying process, the drying temperature of materials should not be higher than 60 ℃ (usually about 50 ℃). Therefore, the temperature of hot air in contact with materials should be different.
For the moisture content of different materials, generally not more than 130 ℃, it is better to control the hot air temperature by stages, which can not only improve the thermal efficiency, but also effectively avoid the death of living bacteria.
According to these characteristics, the belt dryer is suitable, because it is suitable for low temperature and low humidity drying, and it can control the temperature of hot air in sections to ensure that the material temperature is not higher than the drying temperature, and maintain the highest temperature in the whole process.
The tail of the dryer can also add natural air cooling part, and cool the material immediately after drying, It can be used many times.
It is very suitable for granular biological fertilizer, with drying permeability, stable and uniform drying of materials, no damage to particles, adjustable residence time and feeding speed to achieve the best drying effect, because most of the thermal circulating air has high thermal efficiency, and the heat source can be used.
There is a secondary granulation area in front of the steam dryer provided by the biogas boiler, The material can be granulated there. Then, the material is lifted up through the plate to be completely dried. The exhaust machine exhausts the humid hot air through the pipe at the end of the dryer, and the air enters the precipitation chamber for precipitation.
After precipitation, the tail gas is removed by the washing tower, and the ejected water is pumped out for recycling. After secondary dust removal, the waste gas is discharged into the atmosphere through the chimney.
(5) Cooling (drum cooler)
The dry material is cooled by belt conveyor and sent to cooler. The cooling process mainly includes using fan to send natural air to cooler through pipe to cool the material.
The wind direction in the cooler is counter current. The waste gas pumped into the settling chamber by fans and pipes is treated and discharged into the atmosphere as dry waste gas
After cooling, the material is screened, the crushed large particle material and the screened powder are transported to the granulator through the return belt for granulation, and the final product is packaged in the automatic packaging system.
Organic fertilizer production line uses organic fertilizer fermentation technology to process animal manure into harmless fertilizer, involving two kinds of probiotics, one is mature bacteria, the other is functional bacteria, which play different roles. The former is a kind of rotten animal manure, while the latter is used to regulate the effect of organic fertilizer.
What kind of bacteria are these probiotics?
Rotting bacteria is a new generation of high efficient manure decomposition agent independently developed. The product contains bacillus, mold and other complex microbiota, rich in protease and cellulase, with the advantages of fast deodorization, strong activity and h
igh efficiency! It has the following functions:
1. Treatment of harmful bacteria in animal feces.
Through continuous high temperature and microbial balance, harmful bacteria, insects, eggs, grass seeds and other crop pests in feces can be quickly and completely killed, and the reproduction of pathogens is inhibited.
2. Deodorize and improve environmental quality
Deodorization is one of the main characteristics of organic fertilizer fermentation. Rotting bacteria can decompose organic matter, organic sulfide, organic nitrogen and so on, which can inhibit the growth of rotting microorganisms and greatly improve the environment of the site.
3. Rich nutrients
In the process of treatment, nutrients change from ineffective and slow effective state to effective and fast action state. To form natural materials with excellent water absorption and retention characteristics, prevent the loss of fertilizer and water, and become a good natural protective film of soil, so as to achieve the role of nutrient enrichment.
Organic fertilizer production line is made of fresh chicken manure and pig manure, and it does not contain any chemical components. However, chicken and pig have poor digestion ability, which can only consume 25% of nutrition, while 75% of the other nutrients in feed are discharged with feces.
Therefore, the dry products contain nitrogen, phosphorus, potassium, organic matter, amino acid, protein and other components.
The reason of fermentation in organic fertilizer production line
(1) In the fermentation process of organic fertilizer production line, the odor produced by compost should be prevented and controlled, and secondary pollution should be avoided. Adding fermentor or fast decomposing bacteria in compost can reduce odor in a short time, and the sensory effect is good. Or the odor produced by composting plant can be treated by biological deodorization technology.
On the one hand, the carbon nitrogen ratio, temperature, humidity, pH value, oxygen content and other nutrients needed for the growth and reproduction of each microorganism strain were satisfied by various factors; On the other hand, different nutrient content will produce different fertilizer effects.
For example, high carbon content can increase soil fungi, nitrogen elements help increase soil bacteria, and calcium has a significant effect on the resistance of crops.
(3) Strictly control the heavy metal content in raw materials to prevent microbial poisoning in the later production process, and the heavy metal content in the organic fertilizer products exceeds the standard, and pollutes the soil and crops.
(4) After analysis and detection, the content of trace elements such as organic matter, humic acid, nitrogen, phosphorus, potassium and the number of living bacteria should meet or exceed the national standards.
Biological fertilizer, namely microbial fertilizer, referred to as bacterial fertilizer, also known as microbial inoculant. It is a special microbial product, which contains a lot of beneficial microorganisms, which can fix nitrogen in the air and activate nutrients in the soil.
In the soil, improve the nutritional environment of plants, or produce active sunlight in the life activities of microorganisms and stimulate the growth of plants. In the production of bio organic fertilizer, bio fertilizer is as important as chemical fertilizer and organic fertilizer.
In fertilizer production line for bio fertilizer, this series of fertilizer machine can use simple composting machine to ferment raw materials, and the fermentation machine will be equipped with fermentation composting machine.
Then, fertilizer crusher, fertilizer mixer and fertilizer crusher will be equipped to deal with the raw materials. We can use chain crusher and horizontal mixer to deal with organic raw materials. Next, in the production of organic fertilizer granulator, it must be equipped with fertilizer granulator in the bio fertilizer production process.
The production of organic fertilizer or bio fertilizer granulating machine can use fertilizer manufacturing technology, and a complete fertilizer production line is designed to produce pelletizer, and different types of fertilizer machines are equipped in the process of fertilizer manufacturing.
The so-called bio organic fertilizer production line is actually the ordinary organic fertilizer production line. The main reason for the difference between biology and common organisms is that in the process of production, the production line of bio organic fertilizer increases the link of adding microbial agents, which leads to the final production of organic fertilizer and bio organic fertilizer.
The production line is organic fertilizer fermentation. In order to better explain the difference between the two production lines, let us first understand the difference between the production process of organic fertilizer and the production process of biological organic fertilizer.
Flow flow of organic fertilizer production line:
The basic process of the production line is as follows: the use of fermentation compost dumper to collect raw materials, and then stack and ferment raw materials can save more time. Next, the raw materials are crushed by the fertilizer pulverizer, and then screened by the screening machine. Raw material, then premixed. Next, the granulator is made by a fertilizer granulator. After granulation, the granulator is treated with a dryer and a cooling machine. Finally, the screening machine is used to screen and pack the high quality fertilizer.
Process flow of bio fertilizer production line:
In the process of bio organic fertilizer production line, raw materials shall be collected first, then bio fermentation with organic fertilizer starter shall be used to complete fermentation of semi-finished organic fertilizer products, then premixes shall be crushed and then pelletized, and then the granulator shall be dried and cooled by the fertilizer dryer dryer and cooling machine. Finally, the second screen and the pelletizer are packed.
From the above two kinds of organic fertilizer production, we can see that fermentation is the first and most important link of organic fertilizer production, because the final use effect of the organic fertilizer is in this link.
With the continuous development of economy, various negative effects caused by environmental pollution also follow. If we can not solve the problem of air pollution for the time being, the consequences will be more serious. While bringing adverse effects to people’s lives, it also directly leads to more dangerous diseases, which makes more and more users use the production process of organic fertilizer and worries many manufacturers. At the same time, users themselves are more worried about this situation. How does the organic fertilizer machine, disposal , welcome go to https://www.wastetofertilizer.com/
The use of users is more concerned by enterprises. In the development of new products, also according to the use of improved. When tracking the after-sales situation, manufacturers usually send appropriate manpower to interview users who purchase organic fertilizer equipment, and record various situations encountered in use, so as to facilitate future production and provide corresponding opinions to users. The use of users directly leads to the research and development direction of new products.
The main problem occurs in the normal use of the process, so it is necessary to conduct proper after-sales tracking. We give users a certain sense of security, provide them with suitable NPK fertilizer granulator, let users know their own equipment, the error will be reduced to a small.
For small farms, there is no need to invest in large quantities of organic fertilizer production lines. Just choose a small device for the current use, and you can add organic fertilizer manufacturing equipment later.
The small-scale organic fertilizer production line reduces the large-scale production line slightly, and the whole process is still the same. This is more suitable for investors with less initial capital and smaller sites. In order to produce organic fertilizer in line with national standards by using organic fertilizer production line, the government will also give certain subsidies.
Small scale organic fertilizer processing equipment can be built without a lot of funds. Some farmers directly invest in organic fertilizer production line. Farmers can also easily ferment and decompose poultry manure in the open space of their own farms.
With the continuous improvement of people’s awareness of food quality, the use of organic fertilizer is increasing, which brings unprecedented opportunities to organic fertilizer producers. The organic equipment needed in the biological fertilizer production line can transform livestock manure into organic fertilizer, effectively realize the recycling of waste, reduce environmental pollution, and greatly save resources.
The production line of powdery organic fertilizer was designed by Zhengzhou SX Compost Turner Machinery for the start-up farmers. We are worried about the high price of organic fertilizer processing equipment, but considering the relationship between farmers’ initial establishment of factories and economic funds, we have no place to dispose of our farm manure.
In addition, it pollutes the environment and has problems such as bad smell. Therefore, our company has designed a small production line of powdery organic fertilizer, which has less investment and quick effect, and does not have to worry about sales problems (self use or local sales). Sales volume). The production line of organic fertilizer is tens of thousands of yuan. The low-cost investment not only solves the problem of environmental pollution, but also increases the income. It can also apply for project subsidies from the local government.
The equipment of powdery organic fertilizer production line includes: organic fertilizer dumper, semi wet material crusher, horizontal mixer (optional parts must be added), drum granulator, drum screening machine, belt conveyor (belt length depends on the site), automatic packaging machine. The area of fermentation tank and production line is about 200 square meters (the area can be reduced according to the actual situation of customers).
In the process of cocoa bean processing, there are a lot of wastes, such as bean shell, seed coat, seed embryo and so on. These wastes are treated and have certain use value. Cocoa waste is mainly bean shell, which contains more protein and fiber, and can be used as feed or organic fertilizer.
Bode shell is rich in nitrogen, phosphorus and potassium. Because the cocoa tree needs more potassium and the content of potassium carbonate in the bean shell is high, the bean shell is very suitable for the production of organic fertilizer raw materials.
Cocoa seed coating is also suitable for use as organic fertilizer. Fertilizer made from seed coating can reduce the viscosity of the soil and play the role of humus and humus. Seed coat is not easy to decompose. In the fermentation of organic fertilizer, seed coating needs to be pretreated, crushed into small pieces, and then composted for fermentation.
The production of organic fertilizer from cocoa waste can be divided into two stages: composting fermentation and organic fertilizer production equipment processing.
Fermentation composting of cocoa waste
The weight of bean shell accounts for a large part of the weight of cocoa fruit itself. After the cocoa beans are removed, the shells are usually discarded in situ. Pod shells are of great value. Therefore, the proximity principle should be adopted in the selection of organic fertilizer production site to facilitate the fermentation of raw materials.
Cocoa processing waste (bean shell, seed coat) is put into fermentation tank, and animal manure such as chicken manure, pig manure and cow manure are all added with regulating raw materials. After high temperature fermentation, harmful bacteria are killed.
Processing cocoa compost with organic fertilizer production equipment
Fermentation compost is produced into fertilizer products by the industrial processing of organic fertilizer production equipment. The basic fertilizer equipment for cocoa composting processing includes fertilizer crusher, mixer, organic fertilizer granulator, rotary dryer, rotary cooler and packaging machine. Different fertilizer products can be produced by different processing technologies.
Bulk mixed fertilizer, also known as BB fertilizer, is composed of two or two or two kinds of high concentration raw material fertilizers with larger particle size, which are mixed in a certain proportion according to the needs of users.
The appearance of this fertilizer seems to be uneven, but its nutrients are actually equivalent to other compound fertilizers. In the production of bulk mixed fertilizer, all raw material fertilizers must be granular, and the particle size is basically similar, so as to prevent the aggregation of the same particle in the production, storage, transportation and use of the mixed fertilizer, and produce a single fertilizer effect.
Application of bulk mixed fertilizer
The formula of bulk mixed fertilizer can be adjusted flexibly, especially suitable for areas with large land area, complex soil types and many crop types. It is widely used in developed countries in the United States, accounting for about 40% of the total consumption of chemical fertilizer.
BB Fertilizer Production Line
Raw materials of bulk mixed fertilizer
Like other compound fertilizers, bulk mixed fertilizers have three grades: high, medium and low. The raw materials used are urea, ammonium nitrate, ammonium chloride, ammonium bicarbonate, super calcium phosphate, monoammonium phosphate, diammonium phosphate, phosphate, potassium chloride and potassium sulfate.
Bulk Fertilizer Blender
Fertilizer granulation production line processes different types of fertilizer granules. Various granular products are processed by fertilizer granulation production line and mixed into different types of special mixed fertilizers by bulk fertilizer mixer. The bulk fertilizer mixer includes multiple silo batching systems, bulk mixed fertilizer mixer and packaging machine. BB fertilizer mixer is the main equipment for producing this fertilizer. It is evenly mixed with different granular fertilizers to ensure the efficiency of fertilizer.
Defects of bulk mixed fertilizer
BB fertilizer has different varieties and different raw materials, resulting in different physical and chemical properties of BB fertilizer, such as uneven particle size and short storage time. Different chemical reactions take place between the mixed fertilizer materials, which makes some finished products easy to dissolve and even become the mud in the packaging bags, thus affecting the fertilizer efficiency.

Slow release controlled fertilizers release nutrients slowly in the soil to meet the nutrient requirements of the whole crop growth period. In the process of NPK fertilizer production, slow release and control of fertilizer are realized by granulation and coating.
Slow release fertilizer means that the release rate of available nutrients in plants is lower than that of fast fertilizer after fertilization in soil. Controlled release fertilizer refers to the regulation of nutrient release according to the set release mode and nutrient absorption law of crops. Release not only refers to the release period of fertilizer, but also refers to the release rate of nutrients in fertilizer, which conforms to the law of crop fertilizer demand.
Ideally, controlled release fertilizer can artificially control the supply and release rate of nutrients according to the nutrient requirements of different stages of crop growth. That is to say, nutrients can be released when crops need them and retained in the soil when they are not needed, so that a single application can meet all stages of crop growth.
NPK fertilizer production line processing slow release controlled fertilizer
NPK fertilizer production line can slow release and control fertilizer through fluidization treatment. The main production processes are: batch processing, mixing, granulation, drying, cooling, screening, coating, packaging. Fertilizer granulator is the key to slow release and control fertilizer processing. It determines the size, shape and hardness of fertilizer particles. Fertilizer granulator determines the appearance of the product, and the physical shape of the product also affects the fertilizer effect.
Rotary drum granulator is usually used for slow release and controlled fertilizer production for granulation. The roller granulator has the advantages of large production capacity, low production cost and spherical particles meet the production requirements of slow release fertilizer. The final stage of NPK fertilizer production and processing is coating. After particle coating, it becomes slow release fertilizer.
In the process of using organic fertilizer production equipment, if the safety in the operation process is strictly observed, the granulation rate will be effectively increased, the energy consumption will be reduced, and the service life of the equipment will be extended. Therefore, from the following aspects, we can adjust the pan granulator to make the fertilizer production reach the optimal state.
1. Strictly control the powder quality
（1） It is strictly forbidden to have iron block, stone larger than 10 mm and wood block larger than 10 mm in raw material discharge and supply of fertilizer production line. Rice bran and sand can not exceed the quality index, too much will cause the low output of the pan granulator.
(2) According to the formula of NK compound fertilizer, the quality of chemical fertilizer and other raw materials should be strictly controlled.
2. Transform the new blade in the CD
The blade of disc granulator is good, and the particle size is uniform and beautiful. The blade is divided into front blade and rear blade, and there is no gap between the two blades.
3. The main technical key of operating the disc granulator
(1) Do a good job in the technical training of personnel before operation, improve the technical quality and operation skills of the staff.
(2) The particle size of compound fertilizer is 70-90 mesh.
4. Select and adjust the nozzle of disc granulator
(1) The working mechanism of nozzle must be mastered when selecting nozzle
According to the hydrodynamics, it is proved that the bigger the pressure is, the smaller the through hole is and the larger the droplet diffusion surface is. At the same pressure, the spray hole is small, the droplet density is small, the spray hole is large, and the droplet density is high.
(2) How to choose the model and specification of nozzle
The smaller (or larger) the feed droplet and the smaller (or larger) the particle size, the lower (or higher) the yield of the fertilizer production line.
The denser (or thinner) the droplets, the higher (or lower) the output of the droplets they make (or smaller).
Chemical fertilizer has a rapid action and exists in various forms such as liquid and particle. Fertilizer is water-soluble, and plants can absorb nutrients immediately. Although this provides a quick nutrition and fast greening, it will never last. Only organic fertilizer can keep plants growing.
Chemical fertilizer can promote plant growth, but it has little effect on stimulating soil life, improving soil texture and improving long-term soil fertility. They can go into the water, but quick results come at a cost, too much use can burn your lawn and crops.
Organic fertilizer is great for plants and soil. If used properly, it will not burn or damage plants. Organic fertilizer stimulates soil microorganism and improves soil structure. Soil microorganisms play an important role in transforming organic fertilizers into soluble nutrients that can be absorbed by plants. Organic fertilizers usually provide secondary and micronutrient requirements, but not in synthetic fertilizers.
The content of N, P and K in organic fertilizer is lower than that in chemical fertilizer, but it can prolong soil fertility. Therefore, the effect of organic fertilizer on plants is usually more subtle. It may take a while to see the results, but the payoff is that plants take a long time to get nutrients and the soil maintains its fertility.
After fermentation treatment, the organic waste is treated by crusher, organic fertilizer granulator and drum dryer to become organic fertilizer.
With the continuous development of science and technology, pure chemical fertilizer and organic fertilizer are difficult to fully meet the actual growth requirements of different soil crops. Therefore, it is necessary for chemical fertilizer plants to use fertilizer granulator to produce various types of organic fertilizer compound fertilizer to improve soil quality, reduce environmental pollution and improve fertilizer efficiency.

Compound biological fertilizer can be used in many fields, such as food, economy, fruits and vegetables.
1. Compound fertilizer can be used as basic fertilizer and top loading fertilizer. A compound biological fertilizer of 1-2 kg per mu is mixed with agricultural fertilizer, fertilizer or fine soil, and then applied to ditches, holes or spray.
2. Trenching and hole application of compound biological fertilizer. The young trees were fed in a circular ditch, 200 g compound bio fertilizer per tree, and 500-1000 g compound biological fertilizer for each tree, which could be mixed with fertilizer or soil.
3. The root was soaked and irrigated with compound biological fertilizer. Add 1-2kg compound biological fertilizer per mu, add 3-4 times of water, soak in the root during the process of crop transplantation, or irrigate the root after transplanting.
4. Mix the compound biological fertilizer into the seed soil. Each square meter of sown soil is mixed with 200-300 grams of compound biological fertilizer before sowing.
5. Adding compound biological fertilizer to potted garden plants. For flower lawn, 10-15 g / kg potted soil can be used as surface fertilizer or basic fertilizer.
6. According to different crops, 1-2kg compound biological fertilizer is mixed with chemical fertilizer per mu, then diluted with appropriate amount of water, and then irrigated with water.
7. Spray compound biological fertilizer on the leaves. Leaf spray should be done at about 500 times dilution or according to the instructions.
1. Compound biological fertilizer should not be mixed with fungicides and herbicides, and the interval of each application must be more than 7 days.
2. It applies compound biological fertilizer after rain or irrigation, shake it before application, and use it immediately after it is ready.
3. The compound biological fertilizer should be stored in a cool and dry place instead of directly on the ground.
Beneficial microorganisms in bio organic fertilizers can propagate in large quantities in soil, form dominant populations, occupy root sites, resist or inhibit the growth and reproduction of other harmful microorganisms (such as pathogenic microorganisms), so as to reduce their chances of infecting crop root layer. Functional bacteria can improve the soil fertility. For example, nitrogen fixing microorganisms can increase the nitrogen source in the soil.
Phosphorus dissolving and potassium dissolving microorganisms can decompose insoluble phosphorus and potassium in soil and make crops absorb and utilize them. Many microbial strains can produce beneficial metabolites, such as vitamins, amino acids, nucleic acids, formic acid, soybeans and other physiological active substances, which can stimulate the growth of crops and enhance the resistance of crops to diseases and stress.
Bio organic fertilizer is rich in nutrients, including amino acids, protein, carbohydrate, fat and other organic components and N, P, K, CA, Mg, s, Fe, Mn, Cu and other elements. These nutrients can not only be directly absorbed and utilized by crops, but also can effectively improve soil fertility, water retention, buffer and supply conditions, providing a good growth environment for crops.
Compared with other fertilizers, bio organic fertilizer not only contains more complete nutrients and functional microbial agents, but also helps to release potential nutrients in soil and promote the proliferation of beneficial microorganisms in crop nitrogen layer.
It also has the advantages of high bioavailability, long action cycle, low cost and no harm to soil and environment. Long term use of bio organic fertilizer can effectively improve the soil, improve the soil fertility, regulate the micro ecological balance of soil and stratum, and improve the disease resistance and insect pests of crops and the quality of crop products.
