摘　　要：在洛川县和长武县的富士苹果园生草栽培试验结果表明,生草栽培明显改善富士苹果园生态环境,增加土壤有机质和N、P、K含量;改善果园小气候,显著降低果园气温和土壤温度的极端数值;有利于害虫天敌的生存与繁衍,降低虫害密度,早期落叶病发病轻;生草栽培对果园土壤水分有保水和争水双重影响,但在渭北正常年份保水作用是主要的,在多雨年份,会加重套袋果实黑点病和红点病的发生。Sod culture test made in the orchard of Luochuan and Changwu county showed, Sod culture could change the environment of orchard observably, such as increase the quantity of soil organism, increase the nutrition elements such as N, P, K. Sod culture could also lower the extreme tempera- ture of the air and soil, and benefit to the survival and propagate of vermin＇s natural enemies, thus decrease vermin′s density, the apple altermaria leaf spot disease decreased. But sod culture＇s influence in orchard water has two sides, it can saving water along with consuming it. Saving water is the main function in Weibei plateau in normal years. In too much rainfall years, sod culture will aggravate occurrence of black spot disease and red spot disease of bagged apples.
