不同堆置措施对树枝堆肥有机物及生物指标的影响

Effects of stacked measures on the organic and biologic indices in branches compost

通过对树枝堆肥采取不同的堆置措施,研究了调节C/N和添加复合菌剂对树枝堆肥有机物含量及生物指标的影响,为园林废弃物的合理资源化利用积累经验。研究结果表明,C/N的调节和复合菌剂的添加均能明显促进挥发性固体的降解,加速堆肥过程中总腐殖酸和游离腐殖酸的分解、提高堆肥中的胡富比、促进胡敏酸形成,有利于加快堆肥的腐熟和堆肥质量的提高,有利于堆温的升高和腐熟的加快。调节C/N并添加复合菌剂的堆置措施比只进行C/N调节的措施更有利于堆肥的快速腐熟以及堆肥产品质量的提高。

The C/N, organic and biologic indices have been detected in branches compost with different stacked measures. The resuits show that, the adjustment of C/N, and the adjunction of complex bacteria can obviously encourage the degradation of volatile solids, speed up decomposition of humic acids and maturity of the compost.
