果皮、菜叶混合垃圾的蚯蚓堆制处理

在果皮、菜叶混合垃圾中，加入不同比例木屑调节C／N比值和含水量后，接种赤子爱胜蚓（Eisenia foetida）进行室内堆制处理，研究适宜含水量、接种密度和温度条件下蚯蚓的生长和繁殖特性以及堆制产物的化学性状。结果表明：蚯蚓堆制处理明显加速有机质矿化，促进有机物料降解，提高堆制产物全N量，降低堆制产物有机C含量和C／N比值。加入木屑虽然在一定程度上抑制了蚯蚓的生长和繁殖，但是，0～30d时25％和40％木屑堆制处理中赤子爱胜蚓生长良好，繁殖较旺盛。相关分析表明，接种蚯蚓并加入25％～40％木屑对促进果皮、菜叶垃圾降解以及提高和改善其化学性状是有效可行的，有利于废弃物的减量化、无害化和资源化。

Vermicomposting of Mixed Waste of Pericarp and Vegetable Offal Using Eisenia foetida

Saw dusts were added to mixed waste of pericarp and vegetable offal sampled from a food market in Weigang of Nanjing, Eisenia foetida was introduced with a proper density into the mixture, which was placed under optimal moisture, and proper temperature in the laboratory. Daily growth and reproduction of Eiseniafoetida were monitored during vermicomposting,and so were dry weight and chemical characteristics of vermicomposts after 60 days of vermieomposting. Results show that Eisenia foetida significantly accelerated mineralization of the organic waste, increased total N and decreased organic C and C/N ratio of the vermicomposts. Addition of saw dusts had a certain adverse effect on growth and reproduction of the earthworms,which,however,developed and reproduced well in the treatments with 25% and 40% of saw dusts during the 60 days of incubation. It is indicated that the addition of saw dusts and inoculation of earthworms are effective and workable to reduce, recycle and reuse the organic waste.
