Organic fertilizer prepared from animal manure and preparation technology of organic fertilizer

Abstract

The invention relates to organic fertilizer prepared from animal manure and a preparation technology of the organic fertilizer. The organic fertilizer is special fertilizer for vegetables and is prepared from components in parts by weight as follows: 40-50 parts of pig manure, 30-40 parts of chicken manure, 3-8 parts of urea, 5-10 parts of humic acid, 3-5 parts of plant ash, 3-5 parts of calcium superphosphate and 0.5-1 part of monopotassium phosphate. The preparation technology is environment-friendly, free of pollution and high in drying efficiency, and the prepared organic fertilizer can meet the requirement of nutrients required by growth of the vegetables, cultivate the soil and increase the yield.

Description

technical field [0001] The invention belongs to the technical field of fertilizers, and in particular relates to a preparation process, in particular to an organic fertilizer made from animal manure and a preparation process thereof. Background technique [0002] Fertilizer is one of the indispensable main means of production in agricultural production. Traditional organic fertilizers mostly come from materials such as single manure and green manure plants. Low nutrient concentration, large volume, unstable quality, and inconvenient application cannot meet the requirements of modern agricultural development. my country has 2 billion mu of arable land and needs 150 million tons of chemical fertilizers annually. It is the world's largest chemical fertilizer importer and nitrogen fertilizer producer. Agriculture Production is inseparable from the input of chemical fertilizers, but long-term large-scale and irrational application of chemical fertilizers has also resulted in reduce...

[0002] Fertilizer is one of the indispensable main means of production in agricultural production. Traditional organic fertilizers mostly come from materials such as single manure and green manure plants. Low nutrient concentration, large volume, unstable quality, and inconvenient application cannot meet the requirements of modern agricultural development. my country has 2 billion mu of arable land and needs 150 million tons of chemical fertilizers annually. It is the world's largest chemical fertilizer importer and nitrogen fertilizer producer. Agriculture Production is inseparable from the input of chemical fertilizers, but long-term large-scale and irrational application of chemical fertilizers has also resulted in reduced soil organic matter content, increased chemical residues, deteriorated physical structures, serious soil compaction, increased salinization, and degradation of comprehensive fertility. A series of problems such as the destruction of microbial flora have seriously restricted the sustainable development of agriculture and the realization of high-quality, high-yield, and high-efficiency agriculture. With the growth of market demand for organic food and healthy food, the production and promotion of organic fertilizers, the development of Organic fertilizer has become an inevitable trend
