A kind of biological bacterial fertilizer prepared from livestock and poultry waste and its preparation method

Abstract

The invention provides biological bacterial fertilizer prepared from poultry and livestock waste. The biological bacterial fertilizer meets the following indexes that the number of effective living bacteria is greater than or equal to 42 million / g; the content of N+P2O5+K2O is greater than or equal to 8%, and the content of organic matter is greater than or equal to 45%; the content of amino acids is greater than or equal to 6%; the content of humic acid is greater than or equal to 5%; the germination index of seeds is greater than or equal to 95%; the content of soluble carbon is smaller than or equal to 0.56; the number of coliform bacteria is smaller than or equal to 60 / g; the mortality of ascaris eggs is greater than or equal to 97%; the fertilizer has no pungent odor. The invention further discloses a preparation method of the biological bacterial fertilizer prepared from the poultry and livestock waste. The method comprises the step of preparing carrier materials; the prepared biological bacterial fertilizer is long in service life and especially beneficial to crop growth and seeding, and has beneficial strains, various enzymes and trace elements such as various vitamins, carbohydrate, cellulose and nucleic acid; the microbial activity of soil can be enhanced, the number of beneficial bacteria in root-layer soil is increased, and the activity of the beneficial bacteria in the root-layer soil is improved.

Description

Technical field[0001]The invention relates to the field of biological fertilizers, in particular to a biological bacterial fertilizer prepared from livestock and poultry wastes and a preparation method thereof.Background technique[0002]Relevant data show that China accounts for 7% of the world’s arable land and consumes 35% of the world’s nitrogen fertilizer, which directly causes up to 90% of China’s farmland soil to undergo varying degrees of acidification. On February 19, 2010, the US "Science" magazine published a report. A paper from a Chinese scientist, Zhang Fusuo, Dean of the School of Resources and Environment of China Agricultural University, and his team found that China’s main farmland soil has undergone significant acidification in the past 20 years, and the culprit is precisely the most important fertilizer variety. -Nitrogen fertilizer. According to the normal amount of nitrogen fertilizer, the grain crop system based on wheat, corn, and rice only needs 15 to 20 kilog...

Problems solved by technology

However, the long-term application of chemical fertilizers and pesticides will harden the land, reduce its fertility, pollute the environment and soil, and affect the sustainable production of agriculture. In addition, the price of agricultural production materials such as chemical fertilizers has risen sharply in recent years, which has increased the cost of agricultural production. Farmers urgently need to find a kind of energy Partial or full replacement of chemical fertilizers, soil improvement, high-quality, efficient, and affordable fertilizers
