Compound microbial fertilizer with continuous cropping resistance and preparation method of fertilizer

Abstract

A compound microbial fertilizer with continuous cropping resistance is characterized by being prepared from raw materials in parts by weight as follows: 45-50 parts of a compound microbial agent, 8-12 parts of a nitrogenous fertilizer, 5-10 parts of a phosphate fertilizer, 8-12 parts of a potash fertilizer, 20-25 parts of organic matter, 20-25 parts of a micro-element fertilizer and 8-12 parts of a synergist. The compound microbial fertilizer with continuous cropping resistance can provide various medium and trace elements essential to growth of crops, replenishes a certain quantity of beneficial bacteria for soil, inhibits growth and proliferation of harmful bacteria, reduces soil-borne diseases to the maximum extent by creating a protective barrier for roots, can sufficiently decompose phosphorus, potassium and minerals difficult to dissolve in soil, and increases the utilization rate of fertilizers.

Description

technical field [0001] The invention belongs to the field of microbial fertilizers, and in particular relates to a compound microbial fertilizer resistant to heavy cropping and a preparation method thereof. Background technique [0002] In the planting process of modern high-efficiency facility agriculture, crops with high economic value are planted repeatedly every year. This agricultural model has caused serious obstacles to repeated cropping in many vegetable production areas. Continuous cropping is also called continuous cropping, which refers to the continuous planting of the same crop on a field. With the increasingly serious situation of desertification and desertification in the world, the arable land is getting less and less, and the contradiction of more people and less land in our country is more prominent. Increasing the multiple cropping index (repeated cropping) is the only way to solve the problem. Many crops, such as legumes, melons, vegetables, strawberries...

AI Technical Summary

Problems solved by technology

[0004] The root cause of the obstacle of repeated cropping is monotonous years of planting a crop, which leads to the imbalance of soil nutrition and the accumulation of pathogenic bacteria of this crop.

Repeated cropping disease has become a key topic of research and concern for agricultural experts and farmers, but there has been no major breakthrough for a long time. At present, there is no suitable compound microbial fertilizer that resists repeated cropping on the market
