Biological organic fertilizer prepared from pig-raising blowdown liquid manure

Abstract

The invention discloses a biological organic fertilizer prepared from pig-raising blowdown liquid manure. The biological organic fertilizer is characterized by comprising a liquid fertilizer and a granular fertilizer. The biological organic fertilizer disclosed by the invention is in solid-liquid separation, thereby being very convenient all in use, transportation and storage, can be used alone and can further be used in combination of solid and liquid states and can improve the growth of roots and seedlings, thereby having obvious effects on stimulating the rapid growth of crops, enhancing the yield and quality of agricultural products and increasing both yield and incomes. The biological organic fertilizer can effectively control the population quantity of soil-borne pathogenic bacteria and has a strong ability to resist soil-borne diseases, thereby being the high-quality fertilizer for producing green agricultural products.

Description

technical field [0001] The invention relates to a fertilizer and a production method thereof, in particular to a bio-organic fertilizer produced by using sewage and excrement from pig raising. Background technique [0002] With the rapid development of my country's economy, the vast rural labor force has gone out to work, resulting in 90% of the traditional farming industry in the vast rural areas of our country to stop farming. In order to ensure people's large demand for meat, the country has to invest heavily in large-scale cluster farming. However, a large amount of excrement after this large-scale breeding has brought serious environmental pollution. For example, large-scale pig farms (40,000 to 50,000 pigs) emit 1.5 million tons of waste and a large amount of excrement per year. If these excrements are not treated in a timely and effective manner, they will seriously occupy and pollute the soil and water bodies, resulting in stench gas and cause serious pollution. ...

AI Technical Summary

Problems solved by technology

This type of existing bio-organic fertilizer has the following disadvantages: the main organic raw material is livestock and poultry manure, so the content of harmful bacteria is relatively high; the stench of livestock and poultry manure will pollute the surrounding air; livestock and poultry manure contains various harmful bacteria and pathogens, which is easy Spread diseases; livestock and poultry feces are easy to breed flies, which will affect the surrounding production and life

The fertilizer effect is single and the beneficial functional bacteria are few, which cannot effectively improve the soil disease prevention, high yield and improve the quality of crops
