摘要
多蜜源植物组合生草模式可形成较长花期,对果园天敌群落动态造成显著影响。为探讨不同生草方式对苹果园主要天敌的影响,本研究在自然生草基础上,适当种植紫花苜蓿、长柔毛野豌豆、孔雀草、万寿菊等显花植物。调查结果表明:苹果园主要天敌有龟纹瓢虫、异色瓢虫、中华通草蛉、食蚜蝇、小花蝽等,2018年组合生草区树冠上天敌总量较2017年增加43.96%,生草中天敌总量增加16.89%。说明增加蜜源植物的组合生草模式对繁育天敌、控制害虫具有重要作用。
The grassy pattern with muti-nectariferous plants could form a longer flowering period,which had significant impacts on dynamics of natural enemy community in orchards.In order to explore the effects of different grassy patterns on the main natural enemies in apple orchard,we planted some flowering plants such as Medicago sativa,Vicia villosa,Tagetes patula and Tagetes erectas on the basis of natural grassy pattern.The results showed that the main natural enemies in apple orchard were Propylaea japonica,Harmonia axyridis,Chrysoperla sinica,Syrphidae,Orius similis and so on.Compared to 2017,the total numbers of natural enemies on trees in combined grassy area increased by 43.96%in 2018,and those on grass increased by 16.89%.It indicated that adding nectariferous plants on the basis of natural grassy pattern played an important role in breeding natural enemies and controlling pests.
