- Abstract:
- To investigate the temporal variations of soil moisture and provide scientific basis for the sustainable development of apple orchards in the gully area in Loess Plateau, we monitored the soil moisture at the depths of 50 cm, 100 cm, 150 cm, 200 cm, 250 cm, 300 cm by ECH2 O during the growing season in an apple orchard in Shanxi Province on the Loess Plateau. The results show that there are significant differences in soil moisture contents among the depths of 50 cm, 100 cm, 150 cm, 200 cm, 250 cm and 200 cm, with the average values of 22.27%, 21.38%, 18.92%, 17.94%, 10.60% and 9.5%, respectively; the precipitation can affect a maximum of soil water content at 100 cm depth; during the study period, the response of soil water content at 100 cm depth to precipitation far lagged behind that at 50 cm depth. In addition, the soil moisture at the depths of 150 cm, 200 cm, 250 cm and 300 cm had no significant responses to the precipitation; the soil moisture showed the decreasing trend with the increase of the soil depth. The precipitation could only affect soil moisture within 100 cm depth. At the 200 cm depth, the soil dessication had occurred in the apple orchard in the gully area in western Shanxi Province on the Loess Plateau.
