摘　　要：[目的]解决北方地区蚯蚓的安全越冬问题。[方法]对蚯蚓进行不同越冬模式的对比试验,探讨北方地区蚯蚓安全越冬的最佳模式。[结果]北方地区蚯蚓安全越冬的最低温度应保持在5℃以上。蚯蚓越冬模式的效果依次为地坑基料加草帘再扣塑料拱棚模式>地坑基料上加草帘模式>地表堆肥加盖草帘再扣小拱棚模式>地表堆肥加盖草帘模式。[结论]地坑基料加草帘再扣塑料拱棚模式为蚯蚓安全越冬的最佳模式。[Objective] The research aimed to solve the safe overwintering problem of earthworm in northern cold regions. [Method]The contrast test was made on different overwintering models of earthworm. And the best safe overwintering model of earthworm in northern cold regions was discussed. [Result] The lowest temperature of safe overwintering for earthworm should be remained above 5 ℃ in northern cold regions. The effects of different overwintering models were as follows： using hollow as the basis,with straw curtain,covered with plastic arched shed 〉using hollow as the basis with straw curtain〉 surface composting,with straw curtain,covered with plastic arched shed〉 surface composting,with straw curtain. [Conclusion]The best model for safe overwintering of earthworm was using hollow as the basis,with straw curtain,covered with plastic arched shed.
