Problems solved by technology

[0005] Straw is the main agricultural waste in rural areas of our country. Although the state has strongly promoted the direct return of straw to the field in recent years, it is difficult to promote it due to reasons such as low fertilizer efficiency and the growth of insects and weeds, resulting in a lot of open burning of straw and air pollution.

Abstract

The invention discloses a preparation method of a biological organic fertilizer, which comprises the following steps: adding crushed first part straw into a first part container, adding a nitrogen source into the first part straw, adding alkali and water into the first part container to adjust the pH value and water content of the substance in the first part container, stirring the components uniformly, and sterilizing the mixture to obtain a sterilized material; cooling the sterilized material, and mixing the trichoderma liquid culture medium with the sterilized material to obtain an inoculation liquid; culturing the inoculation liquid to obtain trichoderma liquid; spraying an aqueous solution containing a nitrogen source onto the crushed second part of straw to obtain a spraying material, mixing the YM strain with the spraying material to form a stacked material, naturally stacking the stacked material for 1-2 days, and starting to turn over for fermentation to obtain a primary fermentation decomposed material; spraying an aqueous solution containing a nitrogen source to the primary fermentation decomposed material with uniform mixing to obtain a secondary fermentation decomposedmaterial, spraying a trichoderma liquid to the secondary fermentation decomposed material, and composting the material to obtain a finished product. According to the invention, the trichoderma, YM bacteria and straw are combined to generate the bio-organic fertilizer.

Description

technical field [0001] The invention relates to the field of organic fertilizer preparation, in particular to a method for preparing bio-organic fertilizer. Background technique [0002] Bio-organic fertilizer is a special organic fertilizer containing specific functional microbial strains. The product not only contains decomposed organic fertilizer, but also contains a specified number of functional bacteria. It is an organic unity of microbial fertilizer and organic fertilizer. On the one hand, the application of organic fertilizer solves the outlet for a large number of organic pollutants, and on the other hand, it greatly reduces the application of chemical fertilizers. It has a double concept of environmental protection and can produce green agricultural products at the same time. Therefore, the key to the production of bio-organic fertilizers is to choose which microorganisms to use as functional bacteria in fertilizers, and which method to use to increase the number o...
