摘要
本文以北京清华园垃圾为饲料,养殖山东海阳“露天红”蚯蚓(Eiseniafoetida)。对盛养容器,垃圾成份、垃圾的预处理条件、养殖的环境条件等进行了试验研究。在试验的条件下,蚯蚓增重倍数:室内盆养日平均为0.3,室外生产性养殖日均0.08,耗饵量为自身重的0.7倍,排粪比平均为0.4,孵化率平均为2条。垃圾中若煤渣成份不超过总量的75％或建筑垃圾不超过50％都可用来养殖蚯蚓。
Solid wastes from Qtnghuayuan in Beijing were used to raise Eiseniafoctida.which were introduced frctn Haiyang of Shandong province. The effects of earthworm raising container, solid waste composition and its pretreatment state, and environmental conditions on the earthworms have been studied. The results show that under the experimental condition, the average day-weihgt increases of the earthworm are 0.3 of the earthworm weight itself in the inside pot raising and 0.08 in the outside productive raising, the consumed solid waste is 0.7 times of earthworm weight, the average excrete ratio is 0.4, and average hatch rate is 2 earthworm. The experiment indicate that the solid wastes, which contain less than 75% of coal breeze or less than 50% of building wastes by weight, can be used to raise earthworm.
