- 摘要:
- 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。
- Abstract:
- Species and dynamics of the major pests were investigated in kernel apricot orchards using chemical pesticide annually for one time intercropping with Scutellaria baicalensis in Beijing.This would be the scientific base for pest management and economic benefits improvement of apricot.The results showed that the species of pests were slightly different between clean tillage and intercrop,while the species and dynamics of main pests were similar.Comparing with clean culture,the number of pests was reduced in kernel apricot orchards intercropped with S.baicalensis.The amount of Tetranychus viennensis (Zacher),Empoasca flavescens (Fab.),Myzu spersicae (Sulzer),Hyalopterus arundimis (Fabricius) was 0.83,0.73,0.21 and 0.55 times than clean tillage orchard,respectively,while the amount of Hypomeces squamosus (Herbst) was 7.40 times than the clean tillage.The composition and quantity of pests were effected in kernel apricot orchard intercropping with S.baicalensis,beneficial for the ecological environment and the production of apricot kernel.
