Problems solved by technology

For a long time, organic fertilizers have been prepared in a decentralized manner by farmers. The method is simple, the treatment level is low, the fertilizer nutrient concentration is low, the volume is large, the quality is unstable, and the application is inconvenient. It cannot meet the requirements of modern agricultural development. my country has 2 billion cultivated land Mu, with an annual demand of 150 million tons of fertilizer, is the world's largest importer of fertilizer and producer of nitrogen fertilizer. Agricultural production is inseparable from the input of fertilizer. However, the long-term and unreasonable application of fertilizers has also reduced the content of soil organic matter. A series of problems such as aggravation of residues, deterioration of physical structure, serious soil compaction, intensification of salinization, degradation of comprehensive fertility, and destruction of beneficial microbial flora have serious impact on the sustainable development of agriculture and the realization of high-quality, high-yield, and high-efficiency agriculture. Restricted, the development of organic fertilizers has become an inevitable trend

Abstract

The invention relates to an organic fertilizer prepared from biogas residues and a preparation process of the organic fertilizer. The organic fertilizer is a fertilizer special for rice and is prepared from components in parts by weight as follows: 85-90 parts of the biogas residues, 5-10 parts of humic acid, 0.5-1 part of monopotassium phosphate, 1-3 parts of monoammonium phosphate, 1-3 parts of diammonium phosphate and 1-5 parts of potassium chloride. The adopted preparation process of the organic fertilizer is environment-friendly, free from pollution and high in drying efficiency, the prepared organic fertilizer can meet growth requirements of the rice and can cultivate soil as well, and the yield is improved.

Description

technical field [0001] The invention belongs to the technical field of fertilizers, and specifically relates to a preparation process, in particular to an organic fertilizer made from biogas residue and a preparation process thereof. Background technique [0002] Fertilizer is one of the main means of production indispensable to agricultural production. Traditional organic fertilizers mostly come from materials such as single manure and green manure plants. For a long time, organic fertilizers have been prepared in a decentralized manner by farmers. The method is simple, the treatment level is low, the fertilizer nutrient concentration is low, the volume is large, the quality is unstable, and the application is inconvenient. It cannot meet the requirements of modern agricultural development. my country has 2 billion cultivated land Mu, with an annual demand of 150 million tons of fertilizer, is the world's largest importer of fertilizer and producer of nitrogen fertilizer. A...
