北方寒冷地区蚯蚓安全越冬模式研究
|
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.
