渭北旱塬不同种植年限苹果园土壤水分的变化特征
Characteristics of soil moisture change of apple orchards of different plangting years in Weibei dryland
摘要
Abstract
Study was conducted on water content of different soil depth in apple orchards of different cultivation years and different yields in the Loess Plateau which belongs to arid and semiarid areas in China. The results showed that, in apple orchards of different cultivation years, the water content in 0 ～ 1 m soil layer changed significantly, and it decreased rapidly with the increase of soil depth; the water content in 1 ～ 2 m soil layer decreased with the increase of soil depth and cultivation years; the water content in 2 ～ 8 m soil layer changed little in different soil depth, but decreased significantly with the increase of cultivation years; and the water content in 10 ～ 15 m soil layer decreased gradually with the increase of cultivation years. In the orchards of different yields, the water content in 0 ～ 2 m soil layer dreased with the increase of yields, and it increased first and decreased then with the increase of soil depth; the water content in 2 ～ 8 m depth stabilized without violent fluctuation, and it was an aquifer in 8 ～ 10 m depth, while the water content in 10 ～ 15 m depth was 15％ without much fluctuation.关键词
