| 摘 要： | 以油枯为基本原料,采用好氧堆肥方式进行堆肥试验,研究了添加4种不同微生物菌剂的条件下,油枯-稻壳-甘蔗渣堆肥体系中pH、C/N、水溶性NO3-N、水溶性NH<'+><,4>-N中的动态变化规律及菌剂对高温堆肥腐熟进程的影响.结果表明,添加菌剂能有效缩短堆肥到达高温的时间,延长高温分解阶段,加快物料水溶性NH<'+><,4>-N和C/N降低,pH和水溶性NO;一N含量升高,加快了油枯堆肥腐熟化进程.添加VT菌剂的堆肥处理相比其他在堆肥15 d后最先进入高温分解阶段,高温持续时间为10 d,提早5 d腐熟,水溶性NH<'+><,4>-N含量从71.41 mg·kg-1增加到887.4 mg·kg-1,C/N的降低有效促进了NH<'+><,4>-N向NH<'+><,3>-N的转化,加快了油枯堆肥化进程,有助于提高堆肥腐熟化程度,说明添加VT菌剂的堆肥腐熟效果相对显著.

| Abstract: | Canola meal,a food processing by product,together with sugarcane residues and rice husks were composted under thermophilic temperature and aerobic condition and the effect of adding four types of microbial strain were evaluated.The temperature,pH value,C/N ratio,water soluble NO-3 and NH+4 contents and compost maturity were monitored throughout the composting process.Our results indicated that adding VT microbial strain could speed up the composting process as indicated by thermophilic stage reached earlier... |
