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

Abstract

The invention discloses an efficient decomposition agent for straw reutilization. The efficient decomposition agent is prepared from the following raw materials in parts by weight: 2-7 parts of a nonionic surfactant, 1.5-4 parts of azotobacter chroococcum, 0.4-0.7 part of sodium alginate, 0.5-1 part of a spore suspension, 0.6-0.9 part of sorbitol fatty acid ester, 0.3-0.8 part of rosin acid polyoxyethylene ester, 0.3-0.7 part of sodium hydroxide, 0.7-1.5 parts of stearyl lactate, 0.4-0.9 part of dimethyl sulfoxide and the like. The efficient decomposition agent and a fermentation process of the efficient decomposition agent have the beneficial effects that the nitrogen loss is small, and the ammoniacal odor in a fermentation workshop is not pungent; the pH value does not exceed 8.5 after the reaction is finished; the fermentation temperature of a composting bottom layer is high in the fermentation process and can reach over 45 DEG C, and the highest composting temperature can reach 80DEG C, so that the evaporation of moisture is promoted, and the drying speed of a fertilizer is increased; the accumulation level of humus in the fermentation process is high; and an organic fertilizer prepared by virtue of the organic matter decomposition agent has the advantages of high germination rate and the like.

Description

technical field [0001] The invention relates to the related technical field of straw processing and reuse, in particular to a high-efficiency decomposing agent for straw recycling. Background technique [0002] Crop straw is one of the most abundant substances in the world. The output of crop straw in the world is about 2.941 billion tons, and the output of crop straw in my country is about 700 million tons per year, including crop straw feed, straw energy, straw papermaking and building materials. It accounts for two-thirds, and one-third is discarded or incinerated. 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 the vast majority of carbon, it also contains elements such as nitrogen, phosphorus, potassium, silicon, calcium, cellulose, and hemifibers. Active ingredients such as lignin, lignin, protein and amino acid. [0003] In recent years, due to the application of large a...
