Abstract: To explore the optimum feeding frequencies on vermicomposting, the effects of seven kinds of feeding frequencies on earthworm growth and substrate nutrient were studied by vermicomposting experiment. The results showed that: the maximum earthworm weight was obtained in the treatment group with feeding frequency of 7 d once, and the average weight  reaching 0.138 7 g per worm. At the same time, the content of total organic carbon was the lowest, and the content of total nitrogen, total phosphorus, available phosphorus and ammonium nitrogen was the highest. Therefore, feeding with the different frequencies could affect the growth rate of earthworms and the efficiency of vermicompost processing, and the optimal feeding frequency was 7 d once.

Key words: earthworm, feeding frequency, composting quality
