【 摘 要 】

In order to clarify the changes in the soil moisture content in different soil layers under different planting patterns, by using the field experiment, the change characteristics of soil moisture content under the treatment of 3 kinds of planting patterns of winter wheat-summer maize (T0), season spring maize (T1) and herbage- spring maize (T2) are analyzed from 2010 to 2011. The results show that the change range of the soil moisture content varies in different soil layers under different planting patterns and the moisture contents of T0, T1 and T2 treatment are the highest in 90-105cm, which are 0.28 m3•m-3, 0.44 m3•m-3 and 0.44 m3•m-3 respectively. Before sowing the spring maize for different planting patterns, T0 and T2 planting patterns decreased with the increase of time and the T1 planting pattern changed little with the increase of time. However, while in the growing season of maize, the soil moisture content of T0, T1 and T2 planting patterns has the consistent trend with the change of time.
