茶树害虫种群分布主要包括水平分布和垂直分布。水平分布一般是指一块茶园、一个地段、一个茶区甚至全国范围内(区域性)的分布,垂直分布是指海拔、地上地下、茶丛上下等不同高度内的空间分布。由于这些分布不同程度地随着茶树的生长期、各种各样的生态条件(时期、季节、温湿度、日照等)及害虫自身的生长发育而多变的,因此,要全面、正确地摸清某一种群的分布动态是比较困难的。1983～1985年,我们结合综防技术基点示范,仅对小绿叶蝉(卵)、茶跗线螨、茶橙瘿螨、茶细蛾、茶蚜五种害虫在茶丛中的垂直(纵向)分布进行了调查,方法是在三块生产茶园中,定期每次分别抽查20个茶枝,检查各序叶或节间上的虫口数,得出了这些害虫在各序叶(节)上的绝对分布量与相对分布率(成数),经过数理统计分析,找出其分布规律性,并试图在害虫综合治理中应用。现将我们的调查研究结果记述如下。
Tea tree pest population distribution mainly includes horizontal distribution and vertical distribution. Horizontal distribution generally refers to a piece of tea plantations, a lot, a tea district and even nationwide (regional) distribution, vertical distribution refers to the elevation, above and below the ground, tea clumps up and down within the spatial distribution of different heights. As these distributions vary to varying degrees with the growth period of tea trees, various ecological conditions (period, season, temperature and humidity, sunshine, etc.) and the pest’s own growth and development, therefore, to fully and accurately touch It is difficult to clarify the distribution of a certain species. From 1983 to 1985, we combined the demonstration base of comprehensive prevention technology with the vertical (vertical) distribution of five pests of the green leafhopper (Egg), Acanthopanax senticosus, Tenebrio molitor, Tenebrio molitor, Distribution of the survey, the method is in the three production of tea plantations, regular checks were 20 times each tea branch, check each leaf or internode on the number of insects, drawn these pests in each leaf (section) on the The absolute distribution and the relative distribution rate (in a few), through mathematical statistics analysis, to find out the distribution of regularity, and try to pest management. Now the results of our survey are described below.
