Grass straw biological organosilicon potassium enzyme fertilizer and preparation method thereof

Abstract

The invention discloses straw biological-organic silicon-potassium ferment bacterial manure and a preparation method thereof. The bacterial manure comprises 60%-80% of straw, 9.89%-19.78% of activated sludge, 10%-20% of beer diatomite clay, 0.1%-0.2% of leavening agent and 0.01%-0.02% of silicate bacteria. The preparation method sequentially includes the following steps: preparation of the materials; heaping and control over C / N; addition of the leavening agent and stirring; capping, heap turning and primary fermentation; addition of the silicate bacteria and after-ripening fermentation. According to the bacterial manure and the preparation method thereof, waste is recycled, the virtuous cycle of natural resources is promoted, and benefits are brought to the nation and people. With silicon as the core, the biological active bacteria are used for treating the straw, the process is simple, the straw returning-to-field production cost is low, the prepared manure can effectively increase and stabilize the yield of crops, and the effect of making the straw profitable is achieved. In addition, the prepared manure can restrain plant roots from absorbing heavy metal, reduce pollution to water and soil, make silicon and potassium in the straw return to the field safely without causing pollution and achieve the effect of recycling the waste without polluting the environment.

Description

technical field [0001] The invention relates to solid waste recycling technology, in particular to a straw biological organic silicon potassium enzyme fertilizer and a preparation method thereof. Background technique [0002] Grass refers to the air-dried stems and leaves left after harvesting seeds of "Rice Beam, Shu, Wheat, and Millet". It is a general term for the stems and leaves of mature crops. Crude cellulose in straw is as high as 30-40%, and is rich in about 15% organic matter (humic acid, humic acid and fulvic acid) and 8-12% silicon (rice), and contains lignin, nitrogen, Compositions such as phosphorus, potassium, calcium and magnesium are a renewable biological resource with a wide range of uses. According to relevant literature reports, the annual output of straw in my country is as high as 800 million tons, which brings about the problem of large area, which needs to be solved urgently. [0003] At present, the disposal method of straw is mainly burning, whic...

Problems solved by technology

[0007] Generally speaking, the disposal of straw in the prior art and the use of straw to produce fertilizer mainly have the following problems: (1) Usually, the carbon-to-nitrogen ratio of straw is about 80:1, which is much higher than the carbon-nitrogen ratio required by fermentation compost , the lack of nitrogen makes straw fermentation very difficult, and it is difficult to ensure the fertilizer efficiency; (2) In the prior art, the method of adding human and animal urine and nitrogen fertilizers is often used to adjust the carbon-nitrogen ratio, but the human and animal urine and feces Nitrogen and phosphorus content is not high enough, fermenting microorganisms can easily absorb nitrogen from the environment, thereby affecting the fermentation speed, and adding more nitrogen fertilizers will cause an increase in fertilizer costs; (3) in the prior art, the addition of Solid waste such as urban domestic sludge, industrial and mining dust, and waste residue to supplement nitrogen, but this method often introduces toxic and harmful substances such as heavy metals, which will cause secondary pollution to farmland and pose a potential threat to human health; (4) straw Rich in silicon content, but it is difficult to be directly converted into silicon and potassium fertilizers required by crops
