摘　　要：在苹果园进行的覆草对土壤肥力和苹果产量与品质的影响试验表明:覆草能有效地稳定土壤温度,保持和提高土壤水分;降低土壤容重,协调土壤大小孔隙比例;增加土壤有机质和养分含量,改善果树营养;提高苹果产量和品质。The experiment was carried out to evaluate the effects of grass covering on soil fertility in orchard and output and quality of apple. The results show that grass covering can effectively stabilize soil temperature, and conserve and improve soil moisture; lower soil bulk weight and improve soil physical characters; improve soil fortility and nutrient condition of fruit trees; and enhance the yield and quality of apple.
