摘　　要：试验旨在研究牛粪中添加玉米秸秆对堆肥发酵的影响。选择牛粪与玉米秸秆比例分别为1∶1、2∶3、1∶3,经过45 d堆肥发酵试验。结果表明,牛粪与玉米秸秆添加比例为2∶3时,升温快,第3 d达到55℃,高温持续时间为23 d,发酵温度最高为69.7℃,种子发芽指数高达97.35%,堆肥达到完全腐熟,符合畜禽粪便无害化处理要求。The purpose of the experiment was to study the effect of adding corn stalks to cow manure on compost fermentation.The ratios of cow dung to corn stalks were selected to be 1∶1,2∶3,and 1∶3,respectively,to carry out a 45 d composting fermentation test.The result showed that under the experimental conditions,when the ratio of cow dung to corn stover was 2∶3,the temperature rises quickly,reaching 55℃in 3 days,the duration of high temperature was 23 d,the fermentation temperature was as high as 69.7℃,and the seed germination index was as high as 97.35%,the compost was completely decomposed,which could meet the requirements for the harmless treatment of livestock manure.
