中文摘要	陇东旱塬为半干旱区,年降雨量偏小且分布不均,果园生草是否会存在与果树争水的问题尚不清楚。为了探讨陇东旱塬果园生草是否存在与果树争水的问题,2014-2015年本试验以果园清耕和果园覆草为对照,探讨果园种植白三叶(Trifolium repens)和鸭茅(Dactylis glomerata)对果园土壤水分及苹果树(Malus domestica)生长的影响。结果表明:果园种植白三叶和鸭茅降低了0~120cm土层土壤水分,土壤水分蒸散量较果园清耕分别提高30.20mm和48.65mm,较果园覆草分别提高29.54mm和47.99mm;果园覆草与果园清耕则基本一致。果园种植白三叶和鸭茅的苹果单果重较果园清耕分别降低7.17%和13.69%,较果园覆草分别降低12.05%和18.22%;苹果产量较果园清耕分别降低14.33%和20.18%,较果园覆草分别降低21.84%和27.17%。果园覆草的苹果单果重较果园清耕提高5.53%,产量提高9.60%。果园种植白三叶和鸭茅的土壤水分利用效率较果园清耕分别降低20.56%和28.99%,较果园覆草分别降低27.39%和35.10%;果园覆草较果园清耕提高9.42%。陇东旱塬苹果园不宜生草,而应覆草。
英文摘要	Dry plateau of eastern Ganshu is semi-arid areas,while annual precipitation is small and has a large inter-annual variety and uneven distribution cross year.The problem of whether interplant herbage compete soil moisture with fruit tree has not a clear conclusion.In order to explore the problem,the experiment was conducted to study the influences of interplant herbage on soil moisture and apple tree(Malus domestica)growth from 2014to 2015.White clover(Trifolium repens)and orchardgrass(Dactylis glomerata)were selected as test herbages and interplanted in apple orchard,and clean tillage and straw mulching were taken as control.The results showed that the soil moisture in 0~120cm soil layer decreased in interplanting white clover and orchardgrass orchard,and evapotranspiration increased by 30.20 mm and 48.65mm,respectively,compared with clean tillage orchard,and increased 29.54mm and 47.99 mm,respectively,compared with straw mulching orchard,but evapotranspiration of clean tillage and straw mulching had no difference.Single fruit weight of interplanting white clover orchard and interplanting orchardgrass orchard decreased by 7.17%and 13.69%compared to clean tillage orchard,respectively, and decreased by 12.05%and 18.22%compared to straw mulching orchard,respectively.Apple yield of interplanting white clover orchard and interplanting orchardgrass orchard decreased by 14.33% and 20.18%compared to clean tillage orchard,respectively;and decreased by 20.56%and 28.99%compared to straw mulching orchard,respectively.Compared to clean tillage orchard,single fruit weight of straw mulching orchard increased by 5.53% ,and apple yield increased by 9.60%.Soil water use efficiency of interplanting white clover orchard and interplanting orchardgrass orchard decreased by 20.56% and 28.99%compared with clean tillage orchard,respectively;and decreased by 27.39%and 35.10%compared with straw mulching orchard,respectively.Soil water use efficiency of straw mulching orchard increased by 9.42%compared with clean tillage orchard.Interplanting herbage in apple orchard as soil management practices should not be used,and straw mulching in apple orchard should be the preference of soil management practices in dry plateau of eastern Gansu.
