Problems solved by technology

[0002] With the effective adjustment of my country's agricultural structure and the rapid advancement of agricultural industrialization, the poultry and livestock breeding industry is gradually becoming large-scale and intensive, resulting in the amount of poultry and livestock manure far exceeding the capacity that the surrounding environment can absorb. The relative lag of management and the limited natural decomposition ability have seriously affected the ecological environment, landscape, and the health of residents; among them, in some places, the pollution of cow dung to the environment has exceeded the total amount of industrial pollution, and some have even reached 2 The manure produced by a dairy cow is more than 7 tons per year, and the manure produced by a yellow cow is between 5 and 6 tons, which has caused great pollution to the environment and has a negative impact on the normal life of surrounding residents. It is the source of a variety of bacterial pathogens and has a serious impact on the breeding population. Therefore, how to deal with and utilize cow manure has become the focus of attention

Abstract

The invention belongs to the technical field of fertilizer preparation, and especially relates to a preparation method of a cow dung organic fertilizer. The preparation method includes steps of cow dung pretreatment, cow dung fermentation, cow dung nutrition cultivation, and mixing. The method takes cow dung as the raw material, the protein, microorganism and other nutrition matters in the cow dung are greatly reserved through the scientific and reasonable preparation method, the pathogenic bacteria and harmful matters are greatly killed, thus the prepared cow dung organic fertilizer is high in fertility, significant in crops yield-increasing effect; the cost is much lower than that of the marketed organic fertilizer; on the basis of harvesting the same output, the cow dung organic fertilizer is lower in price, and can significantly increase the economic benefit of farmer households.
