| 摘 要： | 温度是影响微生物分解堆肥物料中的有机质和堆肥工艺过程的重要因素.通过添加凹凸棒石粘土的鸡粪好氧堆肥试验,结果表明凹凸棒石粘土与鸡粪的质量比为3∶7或4∶6的处理条件下,堆体的升温速度明显高于其他处理,堆体温度维持在50～60℃的时间达到12d,显著长于其他处理.凹凸棒石粘土添加明显提高了鸡粪堆肥的温度,延长了堆体的高温持续时间,改善了腐熟过程,提高了堆肥质量.研究结果对于畜禽粪便的堆肥处理具有生产实践指导意义.

| Abstract: | During composting process,temperature was important in the activities of microorganisms,which was the main factor of composting.The aerobic composting experiment for different proportion of attapulgite which were added into chicken manure was carried out to measure the temperature.The results suggested that the speed of increasing temperature compost in 3∶7 and 4∶6 in mass proportion of attapulgite to chicken manure was faster than other treatments,and the standing time of pyrolytic period in 50～60℃ reached 12 days which was significantly longer than other treatments.Addition of attapulgite can extend the composting pyrolytic period and increase the temperature of compost,ameliorate ferment period,improve quality of compost.The results were helpful for harmless composting of animal manure. |
