摘　　要：[目的]研究复合酶添加对牛粪堆肥组分的变化。[方法]试验设置2.0%酶处理组、1.5%酶处理组及对照组,对牛粪堆肥期间的温度、水分、pH值、粗纤维、总有机碳(TOC)、全氮(TN)及发芽指数(GI)进行分析。[结果]添加复合酶牛粪堆肥,加速了堆肥前期有机物的降解。堆肥期间2.0%酶处理组、1.5%酶处理组和对照组的粗纤维分别下降了49.6%、47.0%和29.1%,TOC降幅分别为41.7%、35.3%和21.1%,全氮降幅(前21d)分别为32.6%、26.8%和19.2%。2.0%酶处理组和1.5%酶处理组堆肥在30d可达到基本腐熟的程度。[结论]复合酶的添加缩短了堆肥周期,有利于牛粪堆肥的腐熟。[Objective] The aim was to study the change of the composition of cow dung compost by adding complex enzyme.[Method] 2.0% enzyme treatment group,1.5% enzyme treatment group and control group were set to analyze temperature,moisture,pH value,crude fiber,TOC,TN,GI during composting.[Result] The results showed that adding complex enzymes could accelerate degradation of organic matter in pre-composting period.Crude fiber of 2.0%,1.5% enzyme treatment group and control group decreased 49.6%,47.0% and 29.1% respectively,TOC decreased 41.7%,35.3% and 21.1%,TN decreased 32.6%,26.8% and 19.2%.2.0% and 1.5% enzyme treatment groups could reach basic maturity degree at 30 d.[Conclusion] Composting cycle could be shortened by adding complex enzymes,which was useful for maturity of cow dung compost.
