Micro-high-efficiency decomposition agent for rice straw reprocessing

Abstract

The invention discloses a micro-high-efficiency decomposition agent for rice straw reprocessing, which consists of the following raw materials in parts by weight: 0.5-1 part of trichoderma harzianum,0.8-1.5 parts of azotobacter chroococcum, 1-6 parts of diglycerin polypropylene glycol ether, 0.3-0.7 part of ACC deaminase, 0.6-1.5 parts of bacillus licheniformis, 0.3-0.7 part of phosphate-solubilizing bacillus megaterium, 0.5-0.9 part of pichia pastoris, 0.2-0.6 part of propylene alcohol polyether and 0.3-0.6 part of yeast. The straw decomposition agent of the present invention can effectivelydecompose lignin, cellulose and hemicellulose in crop straw, has short degradation time, and stable decomposition effects, can effectively kill diseases and insects, and has a decomposition effect atroom temperature, rapid treatment of organic materials and ultimate resource utilization are realized, the treated organic solid waste is thoroughly changed, and the advantages of improving soil, promoting growth, inhibiting soil-borne diseases, environmental protection and hygiene are achieved.

Description

technical field [0001] The invention relates to the related technical field of straw processing and recycling, in particular to a trace and high-efficiency decomposing agent for rice straw reprocessing. Background technique [0002] Crop straw is one of the most abundant substances in the world. The world's crop straw output is about 2.941 billion tons. my country's annual crop straw output is about 700 million tons, including crop straw feed, straw energy, straw paper and building materials. Two-thirds, and one-third were discarded or burned. Crop straw is an important resource in the crop production system. It contains a variety of effective components that can be used. In addition to carbon, it also contains nitrogen, phosphorus, potassium, silicon, calcium and other elements, as well as cellulose and hemifiber. Active ingredients such as pigment, lignin, protein, amino acid, etc. [0003] In recent years, due to the application of a large amount of chemical fertilizers ...

Problems solved by technology

The method of directly returning straw to the field can increase soil organic matter and improve soil physical and chemical properties, but the straw decomposes slowly, and its active ingredients are rarely used in the current season, which is not conducive to farmland operations. Therefore, a crop straw decomposing agent is explored and launched to make crops Straw decomposes quickly, improving the operability of straw returning to the field or applying straw compost to the farmland after making organic fertilizer, which has very important practical significance for promoting the sustainable development of agriculture

[0004] Most of the existing biological straw decomposing agents use filter mud, cassava bagasse, and bagasse ash as raw materials. After adding straw, microorganisms cannot be quickly revived, colonized, and the enzyme activity of microorganisms is low. It is not easy to use straw to quickly decompose. Improve

In addition, we also retrieved other domestic methods of producing straw decomposing agents, most of which use wheat bran and rice bran as raw materials, and the production cost is relatively high; the produced decomposing agents have low bacterial activity and poor decomposing effect; Using a single strain, the amount of enzyme production is small, and the decomposing effect is not obvious
