| 摘 要： | 为探讨蚯蚓堆肥时适宜的添料频率，通过饲养试验研究了7种添料频率对蚯蚓生长及基质养分的影响。结果表明：添料频率为7 d一次的处理组中能获得最高的蚯蚓体重，蚯蚓平均体重达到0.138 7 g·条-1。同时，该处理中基质总有机碳含量最低，总氮、总磷、速效磷和铵态氮含量最高。添料频率会影响蚯蚓生长和堆肥效果，最佳的添料频率为7 d一次。

| 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. |
