| 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 l
ayer 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. |
