Abstract

The invention provides a compound microbial agent for straw turnover, and a preparation method and application of the compound microbial agent. The compound microbial agent comprises fungi and bacteria, wherein the bacteria include lactic acid bacteria, Acetobacter pasteurianus and Sphingomonas xenophaga. The compound microbial agent can quickly compost straws in about 15 days, meanwhile, the nutrient substances of soil are increased, the content of total nitrogen, available phosphorus, organic matters and rapidly available potassium is increased, and the compound microbial agent is favorablefor the growth of crops, inhibits reproduction of harmful bacteria and reduces accumulation of organic acid.

Description

technical field

[0001] The invention belongs to the technical field of agriculture, and relates to a compound microbial bacterial agent for returning straw to fields, a preparation method and application thereof. Background technique

[0002] Crop straw is rich in nitrogen, phosphorus, potassium, calcium, magnesium and organic matter, etc. It is a multi-purpose renewable resource, but currently only part of the straw is reused, and most of it is burned as fuel, which is not only wasted resources, but also seriously pollute the air. Reasonable straw returning to the field can increase soil organic matter, improve soil structure, loosen the soil, increase porosity, reduce capacity, and promote microbial activity and crop root development. Straw returning to the field has a significant effect on increasing fertilizer and production. However, if the method is improper, it will also lead to the increase of soil pathogens, aggravation of crop diseases, lack of seedlings, stiff see...
