Preparation method of aerobic-fermentation organic fertilizer

Abstract

The invention discloses a preparation method of an aerobic-fermentation organic fertilizer. The method comprises the following steps that 1, straw and livestock excrement are adopted as fermented materials, the harvested straw is subjected to crushing treatment by means of a crusher, and the livestock excrement is subjected to dehydration treatment; 2, the treated straw and livestock excrement aresent into an intelligent high-temperature fermentation tank, through a heating device, the temperature of the intelligent high-temperature fermentation tank is improved to kill infectious microbes inthe livestock excrement, then a fermentation microbial agent is added into the intelligent high-temperature fermentation tank, the weight of the added fermentation microbial agent is 0.05%-0.1% of the weight of the fermented materials, then stirring is conducted constantly while air is introduced for aerobic fermentation, and after fermentation is completed, an organic fertilizer product is obtained. According to the method, the straw and the livestock excrement are reasonably used, the harmful infectious microbes in the livestock excrement can be effectively removed, meanwhile, the fermentation rate in the preparation process is high, the fermentation microbial agent can be fully used, and the efficient ideal biological organic fertilizer can be obtained.

Description

technical field [0001] The invention belongs to the technical field of agricultural fertilizers, in particular to a method for preparing aerobic fermented organic fertilizers. Background technique [0002] With the development of agriculture and livestock and poultry breeding industry, more and more wastes such as straw and livestock and poultry manure are produced. At present, most of the straw is directly incinerated throughout the country, which not only pollutes the air, but also wastes a lot of resources. Livestock and poultry manure contains a large number of harmful bacteria. If it is directly used in agricultural production, it will not only reduce the fertilizer efficiency, but also bring harmful substances into the food chain. In view of the above problems, it is necessary to develop a new type of organic fertilizer that can rationally utilize straw and livestock manure. In addition, in the existing organic fertilizer preparation process, the fermentation time is...
