三种管理模式仁用杏园主要害虫与天敌动态研究
Temporal dynamics of main pests and natural enemies in kernel-apricot orchards under three different management models
摘要
Abstract
In order to provide a novel management model to improve kernel-apricot orchards' biological stability and economic efficiency,temporal dynamics of species diversity index,species number and amount of pests and natural enemies were used to analyze the three different models,which were natural grass model,intercropping Scutellaria baicalensis Georsi model and clean tillage model held in Yanqing County,Beijing.The results showed that:The first two models had higher diversity indices;The kernel-apricot orchards under natural grass model showed the highest pest number,followed by the clean tillage model and the intercropping S.baicalensis Georsi model;The kernel-apricot orchards under intercropping S.baicalensis Georsi model had the highest proportion of natural enemies,followed by the clean tillage model and the natural grass model.Compared with other two kernel-apricot orchards management models,the intercropping S.baicalensis Georsi model attracted natural enemies and promoted biological stability in kernelapricot orchard.关键词
