Biological bacterium agent for composting straws and preparation method thereof

Abstract

The invention discloses a biological bacterium agent for composting straws and a preparation method thereof. Diseases and insect pests in the straws are eliminated through the advantages of florae ina composting agent and high temperature generated by rapid fermentation; meanwhile, organic nutrient components of the straws are decomposed into organic fertilizer, so as to keep the ecological balance of soil, inhibit the diseases and insect pests and promote the production of crops. In order to realize the aims of the invention, the technical scheme provided by the invention is a straw composting agent; the straw composting agent is prepared from the following raw materials according to the following content: 22 percent of trichoderma harzianum, 22 percent of trichoderma viride, 15 percentof bacillus subtilis, 15 percent of bacillus megaterium and 20 percent of bacillus thuringiensis. Desired requirements are met through reasonable proportioning.

Description

technical field [0001] The invention designs a bacterial agent for decomposed straw and a preparation method, belonging to the field of microbial bacterial agents. Background technique [0002] At present, pesticides and chemical fertilizers are widely used in agricultural operations. Although it has improved the quality and efficiency of agriculture, the long-term use of pesticides and large amounts of chemical fertilizers has caused the content of soil organic matter to decrease year by year, resulting in soil compaction, acidification, and serious nematode damage. However, the pests and diseases of crops are always an important factor that seriously affects the yield of crops, and the occurrence of pests and diseases has seriously reduced the yield of crops. Because there is no effective way to deal with the large amount of straw produced by farming, it is generally discarded or burned on the spot, causing serious and huge environmental pollution, and posing a great threa...

Problems solved by technology

[0002] At present, pesticides and chemical fertilizers are widely used in agricultural operations. Although it has improved the quality and efficiency of agriculture, the long-term use of pesticides and large amounts of chemical fertilizers has caused the content of soil organic matter to decrease year by year, resulting in soil compaction, acidification, and serious nematode damage.

However, crop diseases and insect pests have always been an important factor seriously affecting crop yields, and the occurrence of plant diseases and insect pests has seriously reduced crop production.

Because there is no effective way to deal with the large amount of straw produced by farming, it is generally discarded or burned on the spot, causing serious and huge environmental pollution, and posing a great threat to the ecological environment and human health and life.
