【摘要】：【目的】油茶新造林特别是纯林不断骤增导致油茶林害虫发生日趋严重,食用茶油安全倍受威胁。为探索有效控制油茶林害虫发生的途径,保护分解者跳虫等土壤节肢动物多样性。【方法】基于Tullgren干漏斗法和巴氏罐法,对半垦复油茶幼林、全垦复油茶幼林、全垦复油茶成林和未垦复油茶成林4种不同油茶林的20个土样和15个凋落物样中的土壤跳虫和土壤其他节肢动物多样性特征进行了研究。【结果】共分离出跳虫315头,隶属6科8属;其他土壤节肢动物11科17种295头。多样性分析结果表明,油茶成林地比幼林地土壤动物的多样性指数高,多样化的地被物有利于提高土壤动物的多样性,垦复和施肥等人为干扰显著地降低土壤跳虫的多样性,却有利于增加罐诱土壤动物的多样性,水源是土壤动物生存的关键因子,对林地跳虫和罐诱动物的多样性提高有显著促进作用。【结论】探明了不同垦复类型油茶林土壤跳虫和土壤其他罐诱节肢动物多样性特征,对合理开展油茶林垦复,发挥油茶林土壤跳虫和土壤节肢动物分解功能提供了科学依据。
[Abstract]:[objective] the new afforestation of Camellia oleifera, especially pure forest, caused the serious occurrence of insect pests and the safety of edible tea oil was threatened. In order to effectively control the occurrence of insect pests in oil tea forest and to protect the diversity of soil arthropods such as decomposers and jumper, [methods] based on Tullgren dry funnel method and Babbitt pot method, the young Camellia oleifera forest was reclaimed by half reclamation, and the young Camellia oleifera forest was completely reclaimed. The diversity characteristics of soil jumper and other arthropods in 20 soil samples and 15 litter samples of 4 different oil tea forests were studied. [results] 315 jumpers were isolated from the whole and unreclaimed Camellia oleifera forests. They belong to 6 families, 8 genera, and 295 heads of other soil arthropods belonging to 17 species and 11 families. The results of diversity analysis showed that the diversity index of soil animals in Camellia oleifera plantation was higher than that in young forest land. But it is beneficial to increase the diversity of soil animals. Water source is the key factor for the survival of soil animals. [conclusion] the diversity characteristics of soil jumper and other pot trap arthropods in different reclamation types of oil tea forest were proved, and the reasonable cultivation of oil tea plantation was carried out. It provides scientific basis for exerting the function of soil jumping insect and soil arthropod decomposition in oil tea forest.
