摘　　要：采用室内模拟培养的方法,利用蚯蚓处理热带农业固体废弃物木薯渣,研究处理过程中蚯蚓生长繁殖状况及处理前后混合废弃物的理化性质,探讨蚯蚓处理热带农业废弃物的适宜条件。结果表明,热带农业废弃物木薯渣和砖红壤的不同配比基质中赤子爱胜蚓的生长繁殖良好,各试验组蚯蚓的生长繁殖与基质性质及环境条件之间存在明显关系,其在30%砖红壤+70%木薯渣的处理中繁殖情况最好,产茧数量最多。蚯蚓在温度25℃、含水率70%、pH 7.9、接种密度10条/60g干重基质时具有最好的生长繁殖效率,同时赤子爱胜蚓对此类热带农业废弃物也具有较好的处理效果,不同配比基质经蚯蚓处理后速效氮和速效磷含量明显增加。In a laboratory incubation experiment, Eiseniafoetida was used to treat cassava dregs, a kind of tropical agricultural solid waste, and the growth and reproduction of earthworms, the physicochemical properties of mixed waste before and after treatment were studied, to find the best ecological conditions of E. foetida in vermicomposting system. The results showed that the combination of laterite and cassava dregs was conducive for growth and reproduction of E. foetida, especially when the ratio of laterite and cassava dregs was 3：7, E. foetida had the best growth and reproduction performance. In addition, the growth and reproduction of E. foetida in all treatments had a clear relationship with environmental conditions. Under the conditions of 25℃, moisture content of 70%, pH values of 7.9 and density of inoculation of 10 ind/ 60g （dry weight）, E. foetida had the best growth and reproductive rate. E. foetida had good effect on this kind of tropical agricultural waste, the contents of available nitrogen and available phosphorus significantly increased after treatment by E. foetida.
