Abstract:
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.
