- 摘要:
- 采用野外观察法和实验室培养法对小白菜地紫跳（Ceratophysella duplicispinosa）的空间分布及其与蔬菜菜叶的生物学关系进行了初步研究。结果表明：小白菜地、生菜地、菠菜地等环境中紫跳分布密度相对于其它土壤环境中较高；无论是在野外还是实验室条件下，所有紫跳都倾向分布于老菜叶或半腐败菜叶上或分布于环境土壤表面，而新鲜菜叶上几乎没有跳虫分布；紫跳在菜田丢弃菜叶快速分解中起重要作用。研究认为，小白菜地紫跳的存在不仅对小白菜无明显危害，而且能够加快老叶的分解，有利于土壤物质循环和能量流转。
- Abstract:
- Spatial distribution of springtail Ceratophysella duplicispinosa and their biological effects to the vegetable leaves in the Chinese cabbage plot were studied by using field and laboratory observation.The results showed that density of the springtail C.duplicispinosa in some vegetable plots including these of the cabbage (Brassica rapa),spinach (Spinacia oleracea) and lettuce (Lactuca sativa Linn.var.ramosa Hort.) was higher than other vegetable plot environments；the springtail tend to distributed on older or semi-corrupt leaves,or on the wet soil surface,and fresh leaves almost no distribution,both in the field and laboratory conditions; the springtail C.duplicispinosa played an important role in decomposing quickly discard older vegetable leaves.The existence of the C.duplicispinosa in cabbage plot was not only no harm,but also accelerate to the decomposition of old leaves and could promote soil material circulation and energy flow.
