Problems solved by technology

However, straw is mainly composed of lignin, cellulose, hemicellulose and other components that are difficult to decompose, and the natural decomposition rate is relatively slow. If the straw is not decomposed and directly returned to the field, it will have adverse effects on soil microorganisms and soil physical and chemical properties.

Embodiment 1

[0016] The prepared straw decomposing bacteria agent was used, and the experimental site was selected in Mishan Farm, Heilongjiang Province, and the previous stubble was corn. After harvesting, the full amount of straw is returned to the field, and the no-tillage method is implemented. There are 4 treatments in the experiment, the area of ​​the plot is about 20m2 (4m×5m), and ridges are built between the plots, and the experiment is repeated 4 times. Field return + equal amount of water; No. 3: full amount of straw returned to the field; No. 4: no straw returned to the field. The experiment was repeated three times.

[0017] Analysis of test results

[0018] Color change of straw: 3 days after the application of microbial inoculants with decomposed straw and returned to the field, the color of the straw that was not applied basically did not change, and the straw was harder. However, the surface of the rice straw applied with the microbial inoculant of straw decomposing and ...

Embodiment 2

[0021] Embodiment 2: using the prepared straw decomposing bacterial agent, straw composting. The experimental site was selected at Jiansanjiang Farm in Heilongjiang Province, and the previous stubble was corn.

[0022] The first step is to use straw to build a 1.5-meter-high base after harvesting, and the width of the base is more than 4 meters.

[0023] The second step is to sprinkle water on the straw at the grassroots level. Sprinkle water evenly, and the amount of water sprinkled on grass-roots straw accounts for about 60% of the weight of grass-roots straw.

[0024] The third step is to spray bacteria and urea. Straw, bacterial agent, and urea need to be compatible according to a fixed ratio. In principle, 1 ton of straw: 2 kg of bacterial agent: 1 kg of urea, evenly sprinkled.

[0025] The fourth step is to cover the upper layer of straw with machinery, and sprinkle water while covering the straw, and the amount of watering for the second time reaches more than 60% of...

Abstract

The invention discloses a straw decaying agent, a preparing method thereof and a method for preparing a straw organic fertilizer through a decaying agent, and relates to the technical field of fermentation, in particular to a fermentation preparation for straw decaying, a straw organic fertilizer and a preparing method of the straw organic fertilizer. The fermentation preparation is prepared from16% of cellulomonas flavigena, 11% of fermentation cytophaga, 11% of bacillus pasteurii, 28% of bacillus cereus, 22% of butyrivibrio fibrisolvens and 18% of fusarium sporotrichioides. Through the decaying agent, the decomposing and returning to field of various types of organic matter, nitrogen, phosphorus, potassium and other elements in straw are promoted and accelerated. The environmental pollution caused by straw combustion is avoided, and the returning to field of the organic matter and the fat reducing and effect improving can be promoted.

Description

technical field [0001] The invention relates to the technical field of fermentation, in particular to a fermentation bacterial agent for straw decomposing, a straw organic fertilizer and a preparation method thereof. Background technique [0002] Heilongjiang Province is the largest agricultural province in China, an important main grain production area in my country, and a province with a large crop straw resource. After the crops are harvested, a large amount of straw is left, and the harvested straw is not well utilized. Burning the straw even brings serious environmental pollution, seriously affecting the living environment and the atmospheric environment. Straw returning technology can effectively solve the problem of straw and realize the resource utilization of straw, thereby promoting the healthy development of sustainable agriculture. However, straw is mainly composed of lignin, cellulose, hemicellulose and other difficult-to-decompose components, and the natural d...
