Abstract

The invention relates to a method for preparing an organic fertilizer. Excrement of livestock can be treated by using the method, so that the purposes of nature and environment protection can be achieved, and the problem of environment pollution can be substantially solved. The contents of total arsenic, total mercury, total lead, total cadmium and total chromium of the organic fertilizer prepared by using the method are low. Meanwhile, the mass fraction of organic matters of the organic fertilizer prepared by using the method is increased by 37.5% when being compared with that of organic matters of the prior art, the mass fraction of total nutrients (nitrogen+phosphorus pentoxide+potassium oxide) is increased by 35.1, the effective viable count is increased by 66.7%, and the fecal coliform group number is reduced by 42.8%. The organic fertilizer prepared by using the method is high in fertilizer efficiency. The acre yield of corn planted with the organic fertilizer prepared by using the method is increased by 15.2% when being compared with that of corns planted with the prior art.

Description

technical field [0001] The invention relates to the field of fertilizer production, in particular to a preparation method of organic fertilizer. Background technique [0002] In recent years, with the development of the economy and the improvement of living standards, the demand for livestock and poultry products has continued to increase, and the scale of production has continued to increase. With the expansion of production scale, the pollution caused by the excrement discharge is becoming more and more serious. The pollution of livestock and poultry manure to the environment is mainly the stench, harmful gas and dust carrying pathogenic microorganisms produced by the anaerobic decomposition of manure organic matter. Malodorous and harmful gases mainly include NH 3 、CH 4 、H 2 S, (NH 4 ) 2 S and skatole etc. Studies have shown that 20%-30% of nitrogen in livestock and poultry manure is ammonium nitrogen, which is easily lost by volatilization. NH 3 Volatilization r...
