新鲜的肉鸡粪水分高,要通过晾晒到水分含量达到50~60%才能堆积发酵。牛粪碳氮比高,在有氧发酵即使添加发酵剂也不宜发酵。肉鸡粪与牛粪混合,能降低含水量,降低碳氮比,使条件更适合有氧堆积发酵。1材料与方法1.1试验材料和地点试验在承德县仓子乡承德瑞赖华龙牧工商开发有限公司有机肥厂进行,牛粪和肉鸡粪来自周边,发酵均为自己研制的发酵菌剂(20%低温发酵菌、30%中温发酵菌,50%高温
Fresh chicken manure moisture is high, to be dried to the moisture content of 50 ~ 60% to the accumulation of fermentation. Cattle dung carbon to nitrogen ratio, even in the aerobic fermentation starter should not be fermented. Chicken manure mixed with cow dung, can reduce the water content, reduce the ratio of carbon to nitrogen, make the conditions more suitable for aerobic accumulation of fermentation. 1 Materials and methods 1.1 Test materials and location of the test Chengde Ruili Hualong Animal Husbandry Industry Development Co., Ltd. Chengde Ruili Hualu animal husbandry and Industry Development Co., Ltd., cow manure and broiler feces from the surrounding fermentation are their own research and development of fermentation agents (20% Low temperature fermentation bacteria, 30% fermentation medium temperature, 50% high temperature
