摘　　要：测量了咸阳庞西村附近苹果林地和玉米地地表以下0～6 m土层的土壤含水量。结果表明,苹果林地土壤含水量从表层向下呈现出高—低—高的变化趋势;10、15龄苹果林地和玉米地冬、春季2、4 m土层土壤含水量分别为14.9%和15.49%、9.96%和10.31%、22.47%和20.68%;15龄苹果林地发育了明显的土壤干层。Soil moisture in 0 - 6 m soil layer in apple and corn land near Pangxi village of Xianyang was determined. The results showed that the soil moisture in apple land from surface layer to low layer showed a change trend of high-low-high. The soil moisture in 2, 4 m soil layer in apple land with 10, 15 years old apple tree and corn land in winter and spring were 14.9% and 15.49% , 9.96% and 10.31% , 22.47% and 20.68% resp. The soil in apple land with 15 years old apple tree developed obvious soil dry layer.
