利用蚯蚓处理污泥、畜禽粪便、植物残体、工业废弃物等已经成为当前有机废弃物资源化利用的有效实例,而处理过程中蚯蚓的生长繁殖变化对有效利用蚯蚓具有重要意义.研究了污水厂活性污泥及污泥与牛粪不同比例条件对蚯蚓平均增重、生长率、日增重倍数、产茧量和蚓茧孵化率等生长繁殖指标的影响.污泥和牛粪分别以1：1、2：1、3：1、4：1、5：1和1：0的比例混合喂养赤子爱胜蚓（Eisenia foetida）,每个配比4个重复,共计24个样品（盆）.每盆基质干物质量为500 g.实验期为60 d.结果表明：在污泥所占比例较大的处理中蚯蚓生长较好,增重较多;污泥所占比例较小的处理则较利于蚯蚓繁殖;其中4：1配比条件下蚯蚓的体重[（17.55±0.30）g]是处理中的最大值,而且平均增重[（354.70±35.30）mg/条]最多,生长率也较高,因此最适合蚯蚓生长.Duncan多重比较结果表明1：1与其他配比条件下蚯蚓总产茧量之间存在显著差异,蚯蚓周产茧量、总产茧量[（538.5±28.3）个]最多,蚓茧孵化率（89.2%）较高,最适合蚯蚓繁殖.

英文摘要：

The technique of using earthworm to clean up sewage sludge, animal feces, plant residue and industrial wastes is an effective way to treat organic solid wastes for recycling. Furthermore, the growth and propagation of earthworm is the key factor for the treatment process. In this study, the variance of earthworms＇ average increased weight, rate of growth, multiple of average increased weight per day, cocoon production and hatchability of cocoon were collected in different proportions of sewage sludge to cattle. Samples of EiseniafiJetida were fed by sewage sludge and cattle dung with the proportions of 1：1, 2：1, 3：1, 4：1, 5：1 and 1：0 with 4 repeated tests, respectively. Totally 24 treatments lasting 60 days were checked in our experiment, and the dry weight of each treatment were 500 g. The results indicated that the growing environment with a higher proportion of sewage sludge to cattle dung was more beneficial to the growth of E../betida, but the rearing condition with a lower proportion of sewerage sludge to cattle dung was more beneficial to the propagation of E. Jbetida. The indices of the weight [（17.55~0.30） g], average increased weight [（354.70~35.30） mg], and rate of growth were all the largest when sewage sludge and cattle dung were mixed with a 4：1 proportion, and the fastest growth of E. foetida was also observed in 4：l. Additionally, the total cocoon production of 1：1 ratio of sewage sludge to cattle dung was significantly different to the vales of other groups （Duncan＇s multiple range test at 5% level）. The cocoon production each week, the number of total cocoon （538.5：k28.3） and hatchability of cocoon （89.2%） in 1：1 were larger than the others, which suggesting that the 1：1 ratio of sewage sludge to cattle dung was theoptimum condition to the propagation of earthworms.
