添加腐熟菌剂对园林绿色废弃物堆肥化效果的影响

Effects of micro- inoculants on garden green waste composting

通过添加微生物菌剂堆肥化处理园林绿色废弃物,量化堆肥过程中主要参数,了解添加微生物菌剂对园林绿色废弃物的堆肥化效果。试验结果表明:添加微生物菌剂可以增加堆体的腐熟程度,表现在菌剂处理温度增加量高于对照处理,特别是在堆置中后期;菌剂提高堆体的电导率值,以堆肥为基质测定的种子发芽率高于对照处理10%左右;相比对照处理,菌剂处理增加了堆体的有机质含量1.8%,对大肠菌含量影响不明显。园林绿色废弃物堆肥各指标均符合国家有机肥标准,均达到无害化处理的效果。

Microbial agents were added into garden green waste,and the main parameters of the composting process were quantified,the inocula add green garden waste composting results showed that adding agents could inerease the heap the decomposition of waste,for the temperature was higher than the control especially during late phase,and germination rate was higher than the control treatment for 10％,and EC value was improved.Agents to handle the increased organic matter content for 1.8％,but the effect on coliform bacteria was not obvious.Various indicators were in line with national standards for organic fertilizer,as the main raw material of garden green waste fermentation at high temperatures by compost.
