摘要
通过比较腐熟菌剂不同添加量在鸡粪椰糠堆肥中物理和化学成分的变化,研究腐熟菌剂对鸡粪椰糠高温堆肥的影响。结果表明：固定鸡粪和椰糠的C/N值为25左右,在其中分别添加质量比0‰（CK）、5‰（F1）、10‰（F2）和20‰（F3）的腐熟菌剂,4种堆肥在堆制过程中p H和电导率（EC）均呈现升高趋势,含水量、有机质和碳氮比均呈降低趋势,至堆肥结束时4个处理p H值均在7.42~7.52之间,EC值均在2 000μs/cm以下。与不加腐熟菌剂相比,添加腐熟菌剂可明显提高堆肥的温度和高温持续时间,最高温度可达62℃左右,持续高温（55℃）时间超过15 d,不同腐熟菌剂添加量之间差异不显著,但添加5‰腐熟菌剂的堆肥总养分含量最高为5%。
In this study,the physical and chemical properties of Chicken Manure and Coconut Husk compost were compareed to determine the effect of different microbial agent on high-temperature composting. The results indicated that C/N keep about 25 and inoculation of functional microbes for 0‰（CK）、5‰（F1）、10‰（F2） and 20‰（F3）,respectively. The p H and EC value of the four treatments all increased along with the composting,but the moisture,organic matter and C/N reduced. At the end of the composting,the p H value of all treatments were among 7.42 and 7.52,while the EC of all treatments all under 2 000 μs/cm.Compare with without inoculation of functional microbes,add inoculation of functional microbes can increase the composting temperature and extend the high-temperture time,and compost temperature reached the highest value of 62℃ among all treatments and high-temperture（over 55℃） sustained for 15 days,but it no-significance for the three inoculation of functional microbes. the total nutrient contents of adding 5‰ of functional microbial agent is 5%.
