Preparation method of organic fertilizer

Abstract

The invention discloses a preparation method of an organic fertilizer, and relates to the technical field of organic fertilizers. The preparation method of the organic fertilizer comprises the following steps that 1, cow dung, chicken manure, pig manure, quicklime, pond mud, yellow bean pods, corn distillers' grains, compound zymophyte, corn straw powder, humic acid, bagasse, wheat bran, peanut cake powder, silkworm excrement, furnace slag, pitaya stems, banana peel, pineapple peel, grape pomace, passion fruit peel, bean curd, expired yogurt, durian peel, coffee residues, rice washing swill, earthworm manure, egg shells, bones, rotten vegetable leaves, shrimp shells, waste tea leaves, spoiled milk powder and trace elements are obtained by weight; 2, the cow dung, the chicken manure, the pig manure and the quicklime are mixed, dried and crushed to obtain excrement powder; 3, the excrement powder is mixed with the rest materials, and fermentation is conducted to obtain the organic fertilizer. According to the preparation method of the organic fertilizer, the fermentation process of the organic fertilizer can be accelerated, the fermentation time can be shortened, the fertility of theorganic fertilizer can be improved, and the disease resistance of plants is improved.

Description

technical field [0001] The invention relates to the technical field of organic fertilizer preparation, in particular to a method for preparing organic fertilizer. Background technique [0002] my country is a large agricultural country, with more than 2 billion mu of cultivated area of ​​crops, and an annual need of more than 140 million tons of fertilizers. Fertilizers are mainly divided into inorganic fertilizers and organic fertilizers. Inorganic fertilizers are also called chemical fertilizers. At present, most of the crops in our country rely on chemical fertilizers. While the extensive use of chemical fertilizers has brought good harvests to agricultural production, it has also led to the sharp deterioration of the physical, chemical and biochemical properties of the soil, the hardening of soil compaction, and the decline of soil fertility, which have negative effects on the natural ecological balance of the soil. Organic fertilizers have the advantages of improving s...

Problems solved by technology

Livestock and poultry manure could have been used as fertilizer, but due to the separation of farming and breeding, it became a source of pollution instead, causing serious harm to water bodies and human health, and even became a medium for spreading zoonotic diseases

Some livestock and poultry manure is directly used as fertilizer for planting, but its utilization rate is also very low, and it is easy to burn the plants without fermentation

At present, the organic fertilizers used in my country are mainly fermented from livestock and poultry manure and soil mounds, which can turn livestock and poultry manure into treasure and solve the problem of environmental pollution, but there are still some shortcomings: First, livestock and poultry manure cannot Fully fermented, the organic matter and nutrients are not high; the second is that the pathogenic bacteria in the manure of livestock and poultry cannot be completely inhibited and killed, and there is potential harm to the crops; the third is that the beneficial microorganisms produced during the fermentation process are Small quantity
