Composite microbial fertilizer capable of preventing vegetable root-knot nematode disease and preparation method thereof

Abstract

The invention relates to a composite microbial fertilizer capable of preventing the vegetable root-knot nematode disease and a preparation method thereof, and belongs to the field of fertilizer production. The composite fertilizer is produced by the following steps: adding carbon containing plant powder and cereal protein powder into a decomposed organic fertilizer to prepare an organic substance, adding functional bacteria into the organic substance, and fully and evenly mixing to obtain the novel multi-resistance composite fertilizer. The functional bacteria can breed massively around the roots of vegetables and crops to form circular protective covers, thus the diseases caused by root-knot nematode are prevented effectively, a good ecological environment is created for the growth of vegetables, at the same time, the soil environment is improved, the soil hardening is avoided, the ventilation and oxygen content of soil are improved, the product quality and output are increased, and the fertilizer has the functions of pesticide and fertilizer. The organic substance content of the composite microbial fertilizer is not less than 50%, and the beneficial bacterium content is 6*10<9> CFU / g. The composite microbial fertilizer is easy to use, the fertilizing effect is high, the fertilizer only needs one application, labor is saved, and the environment is protected.

Description

technical field [0001] The invention belongs to the technical field of fertilizer production, and in particular relates to a compound microbial fertilizer for preventing vegetable root-knot nematode disease and a preparation method thereof. Background technique [0002] Vegetable root-knot nematode is a kind of important plant pathogenic nematode that seriously damages economic crops and is widely distributed all over the world. It can infect not only economical food crops, vegetables and ornamental flowers and trees, but even weeds. Root-knot nematode disease can reduce the yield of commercial crops by 10-20%, and in severe cases, it can reach more than 75%, and even lead to crop failure. At present, the diseases caused by root-knot nematodes have seriously restricted the development and stable production of crops in protected areas in my country, and affected the sustained, rapid and healthy development of the national economy. [0003] Existing microbial organic fertili...

At present, diseases caused by root-knot nematodes have seriously restricted the development and stable production of crops in protected areas in my country, affecting the sustained, rapid and healthy development of the national economy

[0003] Existing microbial organic fertilizers and microbial fertilizers, adding functional bacteria to prevent vegetable root-knot nematodes have general effects, and the amount of application is small, the method of fertilization is inappropriate, the ratio of nutrients in the matrix is ​​unreasonable, and the functional bacteria cannot be effectively supplied. Propagation and growth, the effect is not obvious, especially for soil-borne diseases, such as fusarium wilt, root-knot nematode, and almost no effect
