摘　　要：利用干湿分离猪粪、木麻黄、花生壳等有机物料,采用好氧高温堆肥方式,研究比较各堆肥体系中温度、水分、养分、pH、C、C/N、发芽指数等指标随时间动态变化特征。结果表明:堆肥前期升温快,堆肥进行到第8～9 d即可达到最高温度;同时堆肥中碳含量、水含量和C/N均迅速下降;木麻黄、花生壳均可用作为干湿分离猪粪的填充料,其最高温度、高温累积天数、发芽指数均可达腐熟度要求,其中以猪粪+花生壳效果较好。Using dry-wet separated pig manure mixed with peanut shell,casuarina and other organic materials in a high——temperature,aerobic composting,the changes in temperature,water content,pH,nutrients,C,C/N ratio and germination index of the compost were determined.The results showed that（a） the temperature of the compost rapidly increased initially with the maximum temperature occurred on the 8th to 9th day;（b） C and water contents,as well as,C/N rapidly declined;and（c） peanut shell and casuarina were suitable as the fillers for the compost,as they met the rotting requirements,such as maximum temperature,accumulated days of high temperature and germination index.The best effect was achieved by using the pig manure＋ peanut shell.
