应用有效微生物对畜禽粪便除臭的研究

为了解决畜禽粪便因恶臭得不到很好利用而且严重影响城乡环境的问题，作者引进研究了日本EM有效做生物技术对畜禽粪便的除臭效果。表明：EM技术能有效地去除畜禽粪便的恶臭，总除氨率为42．12％～69．7％。经EM技术处理的饲料，营养成分显著提高，17种氨基酸总量提高28％；其兼有促进畜禽生长，提高机体免疫力、增加产量的作用。应用微生态工程技术净化养殖场环境投资少、设备简单、无任何污染物产生。

A Study on the Application of Effective Microorganisms to Deodorize Animal and Poultry Dung

Animal and poultry dung can not be used well for its bad smell to the surroundings. In re cent years, We have coorperated with the International Research Development Centre of the Japanese Nat ural Agriculture and intraduced the EM, based on the principle of microecological engineering technology,to deodorize the foul smell of the animal and poultry dung. The results showed that application of EM can deodorize the foul smell of the animal and poultry dung, the deammonia rate was 42. 12%~69. 7%; the concentration of amino acids in EM fermented foodstuff increased 28%. At the same time EM also improve the growth of animal and the disease resistance of the animal body. The application of micro-ecological technology could clean the farm yard environment with a little investment, simply and without pollutions.Some useful methods are approached and proposed for the sustainable agriculture and animal husbandry de velopment.
