以全年仅用1次农药的北京延庆仁用杏主产区杏园为例,研究了仁用杏园在间作黄芩的生态条件下害虫种类及主要害虫发生动态和特征。结果表明:间作黄芩和清耕仁用杏园的害虫种类略有不同,但主要害虫(螨)的种类相同、年发生动态相近。与清耕相比,间作黄芩的杏园害虫发生数量少,山楂叶螨、小绿叶蝉、桃蚜、桃粉蚜的发生量分别是清耕杏园的0.83、0.73、0.21、0.55倍,而绿鳞象甲的发生量是清耕杏园的7.40倍。杏园间作黄芩,改变了主要害虫的组成和数量,有利于杏园生态环境和杏仁生产。
Taking the apricot orchard in Beijing Yanqing main apricot producing area as an example, the pest species and main pest occurrence dynamics and characteristics under the ecological conditions of Scutellaria baicalensis Georgi were studied. The results showed that the species of pests of Scutellaria baicalensis and Qing apricot were slightly different, but the main pests (mites) were the same in type and their annual dynamics were similar. Compared with the tillage, the occurrence of apricot garden pests of Scutellaria baicalensis was less, and the occurrence of hawthorn spider mites, small green leafhoppers, peach aphids and peach aphids were 0.83, 0.73, 0.21 and 0.55 times of that of Qing apricot The occurrence of green scales like A is 7.40 times clear apricot cultivation. Asparagus garden between the apricot, changed the composition and quantity of the main pests, is conducive to apricot ecological environment and almond production.
