Things needing attention in applying bacterial fertilizer
Matters needing attention in applying bacterial fertilizer. Bacterial fertilizer, also known as biological fertilizer, does not contain nutrients needed for plant growth and development. It is a new type of pollution-free compound biological fertilizer developed through scientific formula and joint processing. There are many microorganisms in the soil, mainly through the life activities of microorganisms to improve the nutritional conditions of crops. Our company produces all the equipment needed for the production of biological fertilizer.
Wrong ways to apply bio fertilizer
1. According to the local conditions, it is not suitable to apply biological bacteria fertilizer in the soil with high sulfur content and rusty paddy field, because sulfur can kill biological bacteria. For the rice field transferred by marsh, the bacterial fertilizer generally did not spread, and the spraying effect was obvious. Because of the bad temperature conditions, bacterial fertilizer is not suitable for high temperature, low temperature and drought farmland. The optimum temperature for bacterial fertilizer application is 25-37 ° C, and the effect is poor when the temperature is lower than 5 ° C or higher than 45 ° C. When the soil moisture content is between 60-70%, the effect of bacterial fertilizer is better. Roller granulation can be used to produce bacterial fertilizer. Bacterial fertilizers should not be mixed with fungicides, pesticides, herbicides, sulfur-containing fertilizers (such as potassium sulfate, etc.) and rice straw ash, because these drugs and fertilizers can easily kill biological bacteria. If you have to use the above medicine and fertilizer, you can apply bacterial fertilizer first, and then spray medicine and weeds after 48 hours. When using bacterial fertilizer for seed dressing, do not mix seeds with bacterial fertilizer, seeds with fungicides.
How to prevent the mixed use of bacterial fertilizer?
2. In addition, it is necessary to prevent the mixed use of bacterial fertilizer and immature farm manure. In the field of chemical fertilizer application for many years, the amount of chemical fertilizer and organic fertilizer can not be greatly reduced when applying biological bacterial fertilizer. Due to the dependence of crops on chemical fertilizer, the use of biological bacterial fertilizer instead of nitrogen fertilizer makes crops unable to adapt. The replacement amount of bacterial fertilizer should be gradually increased to replace 30%, 40% and 60% of nitrogen fertilizer in two and three years respectively. Phosphorus and potassium fertilizer can only make up, not reduce. Biological fertilizer is not a quick acting fertilizer that changes with time. It is effective when applied 7-10 days before the critical period of crop nutrition and nutrient absorption period.
