【摘要】 通过鸡粪与麦草静态高温好氧堆肥,对接种微生物菌剂的堆肥处理与不接种微生物菌剂的常规堆肥过程中温度、碳氮比(C/N)、铵态氮、以及种子发芽指数(GI)的变化进行了比较分析。结果表明,与不接种微生物菌剂比较,接种微生物菌剂CM和JM堆肥温度提前3 d达到最高温度60℃;接种微生物菌剂CM和JM堆肥经过14 d其C/N就由30降为15以下,较不接种提前10 d;接种微生物菌剂CM和JM堆肥经过20 d其NH4+-N含量分别达到1.42、1.54 g.kg-1,显著低于对照的2.01 g.kg-1;经过14 d的堆肥处理,接种CM、JM菌剂以及不接种的堆肥GI分别为57、48、32。研究表明,接种微生物菌剂CM、JM有助于麦草和鸡粪的快速腐熟,接种CM菌剂较接种JM菌剂有助于堆肥质量的提高。更多还原

【Abstract】 This paper introduced the effects of microbial inoculant CM and JM on the process and quality of hot composting with wheat straw and chicken manure in a static state,such as temperature,carbon nitrogen ratio(C/N),ammonium nitrogen(NH4+-N),and germinating index(GI) were determined.The results showed that,compare with no inoculant(CK),composting inoculated with CM and JM reach highest temperature ahead of 3 days;the C/N of composting inoculated with CM and JM drop from 30 to 15,ahead of 10 days compare with CK;by composting of 20 days,the NH4+-N content of composting inoculated with CM and JM reach 1.42、1.54 g.kg-1 respectively,less than 2.01 g.kg-1 of CK obviously;by composting of 14 days,the GI of composting inoculated CM,JM and no inoculant is 57,48,32 respectively.The results indicate that CM and JM can improve the composting of wheat straw and chicken manure decompose rapidly,CM can increase the value of GI of compost compared with JM.更多还原
