摘　　要：利用蚯蚓的生理代谢活动来处理生物垃圾,从而改变土壤的理化性质,提高土壤肥力,改善土壤中的氮、磷和钾等元素的含量,同时蚯蚓自身也得以存活和增殖。试验通过测定经蚯蚓消化代谢后的生物垃圾,从产物中找出氮、磷、钾的变化规律。同时试验表明蚯蚓的周繁殖率为34%,单独个体日处理生物垃圾量为0.957 g。利用蠕虫(蚯蚓)对生物垃圾进行处理不仅可获得良好的环境效益、生态效益,同时通过蚯蚓增殖更可获得较好的经济效益。The bio-wastes are treated through the activities of the earthworm to improve the physical and chemical property and increase the fertility of the soil. The contents of nitrogen, phosphorus and potassium in the soil were enhanced. At the same time, the earthworms grew very well. The changing rules of the contents of nitrogen, phosphorus and potassium in the soil were found. The breeding percentage of the earthworms was up to 34%. changing amount of individual digestion d treat bio-waste was 0.957 g/d. The environmental, ecological and economical effects can be achieved through the bio-wastes treated the earthwoms.
