Soil microbial regulator for wheat-maize crop rotation field and preparation method of soil microbial regulator

Abstract

The invention discloses a soil microbial regulator for a wheat-maize crop rotation field and a preparation method of the soil microbial regulator. The soil microbial regulator is prepared from the following raw materials in parts by weight: 15-25 parts of amino acid raw powder, 5-10 parts of 100,000 U / g cellulase, 10-22 parts of bacillus subtilis, 10-22 parts of bacillus amyloliquefaciens, 5-15 parts of saccharomycetes, 5-15 parts of trichoderma viride and 5-10 parts of beauveria bassiana. The soil microbial regulator can give consideration to stimulation of soil indigenous bacteria, stimulaterapid propagation of the indigenous bacteria and achieve the purpose of original ecology. The soil microbial regulator is used for soil of wheat planted after maize straw is returned to the field, the tillering number of the wheat can be increased to a remarkable level, and the thousand seed weight of the wheat can be increased to be close to the remarkable level.

Description

technical field [0001] The invention relates to the technical field of soil improvement, in particular to a wheat-corn rotation field soil microbial regulator and a preparation method thereof. Background technique [0002] Wheat is one of the largest and most important crops in the world. As the demand for wheat is increasing year by year, fertilization is the most important way to increase the yield per unit area of ​​crops. Long-term over-reliance on chemical fertilizers has become a bottleneck restricting the sustainable development of agriculture. 【1】 (Wang Xudong, 2001). Corn is the largest food crop in my country, and corn stalks, as its biological by-products, are extremely rich in resources 【2】 (Li Chunyan, 2015). With the decline of soil nutrient content in my country's cultivated land, the deterioration of physical and chemical indicators and the emergence of groundwater pollution, etc. 【3】 (Kuang Enjun, 2012), corn straw returning to the field as a supplementa...

AI Technical Summary

Problems solved by technology

[0013] Although the prior art discloses a variety of soil conditioners, there is no specific research, development and application for the soil problems of wheat planted after corn stalks are returned to the field

Existing soil conditioners cannot be directly used in the soil of wheat planted after corn stalks are returned to the field, and they cannot take into account the stimulation of the native bacteria in the soil and cannot stimulate the rapid reproduction of the native bacteria to achieve the original ecological purpose
