摘要
以30%银杏残叶与猪粪作为堆肥原料,秸秆作为调理剂,研究微生物菌剂添加与否对堆肥过程及效果的影响。结果表明,高温阶段(>55℃)可维持7 d左右,添加一定量的微生物菌剂可缩短堆肥腐熟时间;在堆肥过程中,p H、有机质含量和全氮含量总体呈下降趋势,全磷和全钾含量在堆肥结束时有一定程度的增加;在堆制21 d时,种子发芽指数达到50%以上,说明已基本达到腐熟。
The windrow composting mode with file-turning was selected to study the effect of addition of microbial inoculants on co-composting of ginkgo used leaves with pig manure and wheat straw. The results showed that microbial inoculants addiion could promote maturity of the compost, as evidenced by the highest pile temperature （ 〉 61.2 ℃ ） and the longest duration of high-temperature period （ one week above 55 ℃ ）. As composting proceeded, the content of pH value, total organic matter and total nitrogen decreased, while the total phosphorus and potassium increased to a certain degree. At 21 days, the index of germination was above 50% ,which indicated that pile was maturity.
