Yield and WUE of Winter Wheat in Bed-planting

Abstract：To study water saving techniques in winter wheat production, the comparison of irrigation and planting patterns on the water consumption of winter wheat, dry matter accumulation, grain yield and WUE were investigated under three irrigation treatments. The results showed that under the different irrigation conditions, with the increase in the number of irrigation, the water consumption of winter wheat was gradually increased, so did the dry matter accumulation of winter wheat, and the yield and water use efficiency first increased and then decreased. In the same number of irrigations, the water consumption of winter wheat in bed-planting is lower than that of flat planting, and dry matter accumulation is higher than that of flat planting. Compared with the flat planting, the water quantity of bed-planting were saved 40%, the production increased from 5.5% to 1 1.3 %, and water use efficiency increased from 0. 17 to 0. 40 kg/m^3. On the basis of the experimental results, it is suggested that the bed-planting pattern in combination with consid- erably deficit irrigation at winter, reviving and booting stages could be worth extending the application in winter wheat production.
