| 摘 要： | 通过实时监测堆肥过程中温度、含水率、pH值的变化情况，对园林植物废弃物堆肥发酵关键技术参数变化进行分析，结果表明：（1）堆体温度条件满足微生物的生长，促进微生物有效分解有机物，经过升温期、高温期、降温期3个阶段．（2）堆体含水率变化基本上达到了微生物生长的最佳条件，含水率保持在50．5％67．50％．含水率总体上呈下降趋势．（3）堆体pH值总体上呈下降趋势，并在第29d后趋于稳定，pH值由8．75降至7．86，呈弱碱性，有利于微生物的生长繁殖．

| Abstract: | Key technical parameters change of garden plant waste composting were analyzed and summarized by real-time monitoring of the composting process temperature, moisture content, and pH value changes. The results showed that： （1） Reactor temperature underwent three stages covering warming, high temperature, and cooling period, which met the needs of the growth of microorganisms, promoting microbial decomposition of organic matter. （2） Reactor moisture content maintained at between 50.5% -67.50%, which was downward in the composting process, and reached the optimal moisture for microbial growth. （3） The trend of reactor pH values was downward in the composting process, and tended to stabilize after the first 29 d. The pH value decreased from 8.75 to 7.86, which was slightly alkaline, and conducive to microbial growth and reproduction. |
