| 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NH4＋-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NH4＋-N和C/N降低,pH和水溶性NO3--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15d后最先进入高温分解阶段,高温持续时间为10d,提早5d腐熟,水溶性NO3--N含量从71.41mg.kg-1增加到887.4mg.kg-1,C/N的降低有效促进了NH4＋-N向NO3--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 and lasted longer.A faster NH4 content and C/N ratio decreases and NO-3 content and pH value increases were also observed with VT strain addition.By adding VT strain,the compost undergoes thermophilica decomposition on day 15,lasted for 10 days and reached maturity earlier by 5 days,and NO-3-N content increased from 71.4 mg·kg-1 to 887.4 mg·kg-1 than without VT.The faster decreases in C/N ratio promoted the conversion of NH＋4 to NO-3,and accelerate the compost maturity.The beneficial effects of VT microbial stain on composting are well demonstrate in our study. |
