为了解浙江省不同种植模式茶园节肢动物的群落组成,于2013—2014年对松阳县4种茶园的节肢动物群落数量、时空格局和茶丛上层益害生物比及其动态进行了调查。结果表明:林间茶园害虫、天敌物种数和总物种数显著大于其它3种茶园;林间茶园天敌个体数最多,丰产茶园害虫个体数和总个体数最多。在垂直分布上,天敌个体数在母穗园、林间茶园中以上层最多,在丰产茶园和两行密植茶园中以中层最多;害虫个体数在丰产茶园、母穗园和林间茶园以中层最多,在两行密植茶园以下层最多,分别占其全株的60%、56%、42%和51%;4种茶园益害个体数比皆以上层最多。在水平分布上,害虫个体数在丰产茶园、两行密植茶园、林间茶园皆以朝北方向最多,分别占其全株的35.0%、26.0%和26.3%;害虫个体数以茶丛内层较多,天敌个体数以外层较多;地上部分林间茶园益害个体数比约是丰产茶园的2倍。表明种植模式可改变群落空间格局和益害比。
In order to understand the community composition of arthropods in tea plantations with different planting patterns in Zhejiang Province, the number, temporal and spatial pattern of arthropod communities and the ratio of pests and their biomasses in four tea gardens in Songyang County from 2013 to 2014 were investigated. The results showed that the number of species of pests, natural enemies and total species in tea plantation were significantly higher than those in the other three kinds of tea plantations. The individuals with the highest number of natural enemies in tea plantations in the forest and the individuals with the highest number of individuals in the high yield tea plantations were the most. In the vertical distribution, the number of natural enemies in the mother-ear garden, forest tea garden in the upper most, in the high yield tea garden and two rows of dense planting tea in the middle of the middle; pest number in the abundance of tea, mother spruce and tea plantations in the middle Mostly, the following layers of dense tea plantations were the most in the two rows, accounting for 60%, 56%, 42% and 51% of the whole plant respectively; In the horizontal distribution, the number of individual pests was in the high yielding tea plantations, the two rows of densely planting tea plantations and the forest tea plantations in the northward direction, accounting for 35.0%, 26.0% and 26.3% of the total plantation respectively. The number of individuals with more natural enemies is more on the outer layer. It shows that the planting pattern can change the spatial pattern and benefit ratio of the community.
