对同一区域内的茶树—板栗、茶树—日本甜柿、茶树—桃树及纯茶园4种类型茶园的蜘蛛种群与小绿叶蝉个体数开展了为期1年的调查,查得4类茶园蜘蛛种数、个体数依次为24种和2182头、24种和2013头、23种和1498头、21种和1250头,小绿叶蝉个体数依次为872头、1216头、690头和1466头。结果表明,间作茶园蜘蛛无论在种类上还是个体数均比纯茶园多,而小绿叶蝉个体数比纯茶园少,说明间作有助于改善茶园生态环境,增加茶园生态系统异质性,显著地提高了害虫天敌蜘蛛种群和个体数量,从而有效地控制了小绿叶蝉的发生与为害。
One-year surveys were conducted on the spider population and the individuals of green leafhoppers in four types of tea plantations - tea chestnut, tea tree - Japanese persimmon, tea tree - peach tree and pure tea garden in the same area. Four types of tea plantation spider species The number of individuals and the number of individuals were 24 species and 2182 species, 24 species and 2013 species, 23 species and 1498 species, 21 species and 1250 species, followed by 872, 1216, 690 and 1466 individuals respectively. The results showed that intercropping tea spiders in both species and individuals were more than pure tea gardens, while the number of individuals was less than that of pure tea gardens, which indicated that intercropping could improve the ecological environment of tea gardens and increase the heterogeneity of tea plantation ecosystems significantly Increased the population and number of spiders of natural enemies of pests, and thus effectively controlled the occurrence and damage of green leafhoppers.
