How to make pellet organic fertilizer products?

The invention relates to the field of fertilizer preparation, in particular to a granular organic fertilizer and a preparation method thereof.

Background technology:

In recent years, the input of chemical fertilizer has increased greatly. Due to the single nutrient type, long-term application of chemical fertilizer can easily lead to unbalanced nutrients in soil and food, resulting in nutrient loss, pollution of the environment, and improper application will reduce the quality of agricultural products. Long-term large-scale application of chemical fertilizers will inhibit the activities of soil microorganisms, resulting in a decline in the ability of soil self-regulation. Therefore, although chemical fertilizers contain high single nutrients and use less, long-term application of chemical fertilizers is not advisable under the increasing attention to the needs of the living environment. Therefore, the development of organic fertilizers is of great importance. Significance.

Farm wastes – Ideal materials

Farmyard manure is the accumulation of pig manure, pig, cattle, sheep and other excrement and human excrement, and the organic fertilizer is accumulated. The source of farm manure is wider and its cost is lower. The nutrient content of farm manure is more comprehensive, its fertilizer efficiency is stable and lasting. In addition to nitrogen, phosphorus and potassium, farm manure also contains calcium, magnesium, sulfur, iron and various trace elements, as well as some substances that can stimulate root growth and all kinds of beneficial soil microorganisms. Agricultural fertilizer can improve soil structure, which is rich in humic acid. It can promote the formation of soil aggregate structure, make the soil soft, improve the water and air conditions in the soil, which is conducive to the growth of root system. It can increase soil fertility and water retention performance, improve soil temperature, and promote beneficial microorganisms in the soil. The activity and reproduction of animals; the fertilizer efficiency of farm manure is long.

Hiddien weaknesses

However, most of the nutrients in unfermented and decomposed farm manure are organic or slow-acting, which can not be directly absorbed and utilized by crops. Only when they are decomposed into quick-acting state can they be absorbed and utilized by crops. Therefore, direct application of unfermented farm manure will slow down the efficiency of farm manure. Moreover, the organic fertilizer obtained by direct fermentation has higher moisture content and is not easy to preserve.

Technological implementation elements:

Based on the technical problems existing in the background technology, the invention provides a granular organic fertilizer and a preparation method thereof.

The invention provides a granular organic fertilizer, whose raw materials include 25-30 portions of pig manure, 10-15 portions of chicken manure, 10-15 portions of cow manure, 10-15 portions of bagasse, 20-25 portions of corn straw, 7-13 portions of corncob, 10-15 portions of pond mud, 3-5 portions of beeswax and 1-3 portions of microbial fungicide.

The granular organic fertilizer provided by the invention is fermented by pig manure, chicken manure, cow manure, bagasse, wheat straw and corncob, and is made into granular form by adding pond mud and beeswax, which has strong fertility and durable fertility, and can effectively improve soil, alleviate soil hardening and improve soil structure; after being used as base fertilizer before sowing, it can be applied to Zhuang village. Crops play an important role in strengthening seedlings and increasing yields.

By adding microbial agents, controlling the species, quantity, fermentation temperature and time of microbial strains, the fermentation substrates such as pig manure, cow manure and chicken manure can be fully fermented, and the macromolecular organic substances can be converted into small molecular substances that can be absorbed by plants with strong fertility. Fermentation products were mixed with pond mud, wheat straw powder and beeswax to form granular fertilizer, which was convenient for preservation and application. Pond mud is rich in nutrients and microorganisms, and it is a high-quality fertilizer. Beeswax plays a binding role. The prepared feed particles are compact and not easy to loosen. Beeswax is a natural substance secreted by bees, which can be decomposed in nature. Compared with chemical binders, beeswax is more green and environmentally friendly.

The raw materials of the invention are all from natural waste resources, so there are no side effects on crops, effectively solving the problem of farming and fertilization, reducing farmer’s planting cost and improving farmer’s income.
