Abstract:

In order to improve water use efficiency of winter wheat in dryland, Field test was conducted to study the effect of different ploughing in leisure period on soil water content, yield and water use efficiency (WUE) of winter wheat in dryland. The results showed that, soil water content was significantly increased at depth of 0-100 cm, 100-200cm especially at winter stage and before sowing according different ploughing in leisure period, obviously it was benefit for germination and winter-overing for winter wheat in dryland. Meanwhile, different ploughing in leisure period could improve soil water content, ear number, increase ear number and grain number per ear, significant increased yield and WUE in following growth stage, and the results showed that, the effect of increase was much better under deep plowing than deep tillage and notillage (CK). In a word, different ploughing in leisure period could improve soil water content, increase yield, and improve WUE, it was a better effected way to achieve yield increase of winter wheat in dryland.
