Research on Integrated Effect Deep Application of Fertilizer and Furrow-Sowing Winter Wheat on Weibei Rainfed Highland

In the paper, the technique of deep application of fertilizer or deep application of fertilizer in leisure stage and furrow sowing were adopted on dryland winter wheat.The effect on the development of winter wheat, yield increase and yield composition, etc. were studied.The ecological effect of deep application of fertilizer or deep application of fertilizer in leisure stage and furrow sowing can improve the development conditions for winter wheat, dryland winter wheat deep application of fertilizer and furrow sowing under arid condition or unsufficient moisture of surface soil layer. It may improve the utilization of soil moisture, while in saline alkali soil the technique was used. It could increase seedling emergence rate because of avoiding the effect of alkali, in areas where cold damages often occur, it could lower the position of tillering node in soil and decrease the percentage of deed seedling and tillers caused by cold attack. Therefore, it is an economical, effective and beneficial method for stable yield increase, lower consumption on arid, infertile land and saline alkali soil in Weibei rainfed highland.
