Problems solved by technology

However, the use of chemical fertilizers has brought great environmental problems, such as low utilization rate of fertilizers, decline of land quality, water pollution, and decline of stress resistance of crops, etc., which greatly threaten the sustainable development of agriculture.
However, organic fertilizers are rich in organic matter and various nutrients, but the fertilizer efficiency is poor during use, and the short-term effect is not obvious, and most of the organic fertilizers use human and animal manure, garbage, and crop residues as traditional organic fertilizers, so it is difficult to target the elements required by the soil sexual supplement

Abstract

The invention discloses a preparation method of an organic composite fertilizer. The organic composite fertilizer comprises following raw materials: livestock and poultry feces, leaf, crop straw, green manure, and sludge manure. The preparation method comprises following steps: the raw materials above are mixed according to a certain ratio; water is added; the mixture is stirred so as to mix uniformly, and is sealed with a thin film in an insulation container; a complex microbial inoculant is added for at least 7 days of fermentation, and the temperature is kept at 25 to 30 DEG C; after fermentation, the obtained composite fertilizer is unsealed, dried, smashed using a pulverizer, and sieved, and then is delivered into a granulator to increase water content, and made into granulate finished products. According to the preparation method, livestock and poultry feces and crop straw are taken as the raw materials, so that pollution is reduced, recycling is realized, and cost is low; green manure is rich in a plurality of active substances such as organic substance, amino acid, vitamin and phytohormone, is capable of protecting crops, and reducing diseases; and sludge manure is made from residual bodies and excrement of animals and plants in shallow water, can be used as base fertilizer, and is rich in nutrients.

Description

technical field [0001] The invention relates to a preparation method of organic compound fertilizer. Background technique [0002] The use of a large number of chemical fertilizers and pesticides has solved the problem of food supply and increased food production. However, the use of chemical fertilizers has brought about great environmental problems, such as low utilization rate of fertilizers, decline of land quality, water pollution, and decline of stress resistance of crops, etc., which greatly threaten the sustainable development of agriculture. However, organic fertilizers are rich in organic matter and various nutrients, but the fertilizer efficiency is poor during use, and the short-term effect is not obvious, and most of the organic fertilizers use human and animal manure, garbage, and crop residues as traditional organic fertilizers, so it is difficult to target the elements required by the soil sexual supplement. Therefore, it is necessary to provide a new techn...
