草粉与猪粪不同配比对蚯蚓生长的影响

Effects of the Ratio of Pig Manure to Grass Powder on Growth of Earthworms

摘要: 动物粪便养殖蚯蚓对开发生态循环养殖和海南国际旅游岛建设具有重要作用。海南地区蚯蚓养殖业正处于新兴发展时期，提高蚯蚓的成活率与整体增重成为蚯蚓生产的重要任务。本课题将动物粪便与土壤及草粉经过合适的配比发酵后培养蚯蚓，观察蚯蚓的成活率及增重情况，结果表明：猪粪便、土壤和草粉按45%:45%:10%的比例制成饲养蚯蚓的基料，蚯蚓的成活率最高达到81.7%，增重量也最大，在生产上可推广应用。

Abstract: Production of earthworms with animal manure provides a good alternative to benign agro-eco- logical circulation, which plays an important role in the construction of agro-ecological circulation and international tourism island of Hainan. Vermiculture in Hainan is a welcomed new industry. How to improve the survival rate and the overall weight of earthworms is an urgent problem demanded in earthworm production. Using the combination of animal manure, soil and grass powder with appropriate ratio for fermentation to feed earthworms was a good try in this article. The results showed that earthworms fed on mixtures of pig manure, soil and grass powder, had the highest survival rate (81.7%) and the highest weight of increment. And the survival rate and weight of earthworms were increased to the demand. The mixtures of pig manure, soil and grass powder were fermented together with the proportion of 45%:45%:10%. Taken together, this method will be applied in the production of earthworms.
