利用牛粪等废弃物生产有机肥试验研究

Research on Product Organic Fertilizer by Utilizing Cow Dung and Wastes

本文主要对肉牛规模养殖场牛粪废弃物利用微生物菌-如金益生菌堆肥化处理,生产出的有机肥,褐色粉状或粒状,有机质、总养分、水分、酸碱度pH、总氮(N)、磷(P2O5)、钾(K2O)、总砷(As)、总汞(Hg)、总铅(Pb)、总镉(Cd)、总铬(Cr)、蛔虫卵死亡率以及粪大肠菌群数均符合技术要求。总结和制定出有机肥制作流程,为肉牛规模养殖场废弃物处理提供科学的依据,以期改善生态环境和提高资源利用率。

Waste of beef cattle industry farm were produced into organic fertilizer by microbial bacteria-Rujin probiotics.Organic fertilizer was brown powder or granular.The indicators of organic fertilizer conformed to the technical requirements.The indicators included organic matter,total nutrient,pH,total nitrogen(N),phosphorus,potassium,total arsenic(As),total mercury(Hg),total lead(Pb),cadmium(Cd),total chromium(Cr),mortality of ascarid egg,number of fecal coliforms.Study selected organic manure composting process production formula,summarizes organic fertilizer production process,provided scientific basis for beef cattle industry farm waste management,in order to improve the ecological environment and improve the utilization rate of resources.
