研究了高含水率对牛粪堆肥化反应的影响，以确定促进堆肥化反应的含水率上限。研究结果表明，在堆肥的早期阶段，嗜温和嗜热微生物在很宽的含水量范围内（37%至74%）都是活跃的。即使在水分含量大于76%的情况下，堆肥温度也会增加到50°C以上。微生物的特定生长速率在水分含量大于80%时是高的，这表明在不使用填充剂的情况下高水分堆肥的可能性。【关键词】堆肥，高水分，微生物活性，温度，奶牛粪便
The effect of high moisture content on the composting reactions of dairy cattle manure was investigated to determine the upper limit of moisture content that can promote composting reactions. The results of the study showed that both mesophilic and thermophilic microorganisms were active over a broad range of moisture content (37 to 74%) during the early stage of composting. Even at a moisture level greater than 76%, compost temperature increased to more than 50°C. The specific growth rate of microorganisms was high at a moisture content greater than 80%, suggesting the possibility of high moisture composting without using a bulking agent.
