为制定创新合理的害虫管理方案提高杏园生态稳定性及经济效益,以北京延庆仁用杏主产区的杏园为例,研究了仁用杏园在3种管理模式(自然生草、间作黄芩、清耕)生态条件下的物种多样性指数、害虫亚群落物种数和个体数量和天敌亚群落物种数和个体数量的全年发生动态和特征。结果表明:自然生草园和间作黄芩园物种多样性指数较高;自然生草园害虫数量最高,其次为清耕园,间作黄芩园最低;间作黄芩杏园的天敌比例最高,其次为清耕园和自然生草园。杏园间作黄芩管理模式可以吸引天敌,控制害虫数量,维护杏园生态稳定。
In order to develop innovative and reasonable pest management programs to improve the ecological stability and economic benefits of apricot orchards, taking apricot orchards in the main producing areas of Yanqing, Beijing as an example, the effects of three apricot orchard management practices Scutellaria baicalensis and Tillage cultivation) under the ecological conditions, the annual dynamics and characteristics of species and individual number of pest sub-community and the number of species and individuals of the natural enemy sub-community. The results showed that the species diversity index was higher in natural pasture and Scutellaria baicalensis, the highest in natural pasture, followed by clear garden and intercropped with Scutellaria baicalensis and the highest proportion of natural enemies, followed by clear tillage Park and natural grass garden. Apricot garden between the management of baicalin can attract natural enemies, control the number of pests, maintain the ecological stability of apricot.
