不同木屑含量对猪粪好氧堆肥过程的影响研究

The Effects of Different Wood Contents on Composting Process of Pig Manure

采用不同木屑含量(7%、10%、13%和16%)为猪粪堆肥的填充料,添加0.3%的微生物制剂,研究堆肥过程中温度、含水率、有机质、腐殖质、C/N比随时间的变化规律。结果表明:4个处理都能使猪粪到达腐熟,但根据试验结果木屑的添加量以10%左右为宜。

The aerobic composting of pig manure with different contents of wood （7%, 10%, 13% and 16% ）added with 0.3% bacterium was studied. The variation of the organic matter, temperature, pH, and C/N ratio during the composting was observed. The results indicate that 10% of wood is the best proportion, which could improve the characters of the manure and speed up the maturity of compost.
