草类在生态果园建设中的作用

从生态学角度综述了草类在生态果园建设中的作用，并总结其在果园土壤、果园微域环境、果树生长的影响等方面国内外近年来研究的新进展。结果表明：果园生草可有效改善果树生态环境，调节地温，提高土壤肥力和蓄水保墒能力；同时有利于增加害虫天敌数量，减轻病虫害和生理病害的发生，减少果园农药的使用量。

The Role of Grass in Ecological Orchards

The role of grass in ecological orchards is briefly reviewed. And the research of growing grass on orchard soil, microenvironment and fruit crops growth were reviewed in recent years.
