Abstract

The invention discloses a biological agent for promoting decomposing of rice straws returning to the field. The biological agent comprises the following compositions by weight percent: 4-40% of a complex microbial inoculant, 4-30% of nutritional ingredients, 10-80% of a soluble carrier and 2-20% of a microelement chelate. The complex microbial inoculant comprises a mixture of at least two ingredients of clostridium, brewer's yeast, bacillus coagulans, lactobacillus acidophilus, lactobacillus plantarum, lactobacillus casei, aspergillus oryzae and white rot fungi; preferably, the aspergillus oryzae is penta-aspergillus oryzae. A preparation method comprises the following steps: preparing a culture medium; culturing at least two ingredients of clostridium, brewer's yeast, bacillus coagulans, lactobacillus acidophilus, lactobacillus plantarum, lactobacillus casei, aspergillus oryzae and white rot fungi in the culture medium, so as to obtain complex microbial inoculant stoste; mixing the complex microbial inoculant, the nutritional ingredients, the soluble carrier and the microelement chelate, so as to obtain the biological agent.

Description

technical field [0001] The invention relates to a biological preparation and a preparation method thereof, in particular to a biological preparation for promoting straw maturity and a preparation method thereof. Background technique [0002] Rice is an important food crop in my country and occupies an extremely important position in food production. For a long time, the increase in rice yield has been attributed to the use of chemical fertilizers in addition to the breeding of high-yield varieties. At present, my country has become a country with a large amount of chemical fertilizers. Excessive and unbalanced application of chemical fertilizers not only causes a decline in the quality of agricultural products, but also causes serious environmental pollution. Crop straw is a huge source of organic fertilizer. Containing a large amount of ammonia, phosphorus, potassium and other trace elements, returning straw to the field can reduce the use of chemical fertilizers, improv...
