Abstract: 【Objective】 In order to provide theoretical basis for making full use of crop stem (wheat stem and corn stem) and cow dung, a trail was conducted to estimate the Eisenia foetida growth and reproduction performance, physico-chemical index of the vermibed in the combinations of the residues .【Methods】 The crop stem and cow dung were combined by the C:N ratio of 20, 25, 30. Each pot include 100g air-dried residue and 8 ind worm, which were sampled at 15d, 30d, 45d, 60d. Growth, reproduction performance and physico-chemical index were determined. 【Result】 The results indicated that individual weight, growth rate, reproduction rate declined with the growth. Growth index had difference among period, C:N ratio and combination（P < 0.05）. Total number of worms increased at first, then declined. Reproduction rate had difference among different C:N ratio（P < 0.05）. TOC and C:N ratio declined with the growth, but TKN increased with the growth, all of them had difference between period, combines and C:N ratio（P < 0.05）.【Conclusion】 Growth and reproduction performance and physico-chemical index had difference between period, combinations and C:N ratio（P < 0.05）.
