| Abstract: |
| n order to make clear the possibility to extend conservation tillage in the south mountainous area of Ningxia, a field experiment including three tillage treatments, namely bed planting, control and planting beside the film, was conducted in Wangwa Village, Pengyang County in 2005～2006.This paper analyzed the relationship between wheat yield, yield components and soil water content under different tillage practices.The results showed that planting beside the film could improve soil water retention, and increase water use efficiency and yield to 33% and 46% than control respectively.Because the bed planting have poor ability of heat preservation, winter wheat are winterkilled, so we discard this mode in that area. |
