苹果园植被多样性在果树害虫持续治理中的作用

Study on the Plant Diversity in Apple Orchards Toward Sustainable Pest Management

在苹果园实施有益植物的人工种植或保留有益杂草,进行有益的地面植被栽培,研究其改善果园生态环境,提高果园昆虫多样性的作用。结果表明:在苹果园行间间作苜蓿、三叶草、白花草木犀、百脉根等可增加果园的植物多样性,为天敌益虫提供栖息和繁衍场所,进而提高有益昆虫多样性,为害虫的自然生态调控提供了保证,对苹果园害虫的持续治理具有重要作用。

The useful plants planted or beneficial weeds retained in the apple orchard was implemented, to study useful planting cover, and to study the improvement of ecological environment, orchards and enhance the role of insect diversity in the orchard. The results showed that between the lines in the apple orchard intercropping alfalfa, clover, white clover plants, Lotus japonicus and other plant orchards could increase the diversity of beneficial insects to natural enemies in place to provide habitat and reproduction, and thus improve the diversity of beneficial insects for pest natural control and provided assurance on the continued management of apple pests.
