【Abstract】 The effects of different sowing rates on growth and development, yield and quality of winter wheat variety Xiaoyan 503 for noodles were studied. The results showed that different sowing rates significantly influenced the growth and death of tillers, the amount of secondary root, the number of spikes, and therefore it could remarkably affected the yield. Each variety and ecological zone had its most suitable density level. In this experiment with Xiaoyan 503 in Guanzhong plain, under the sowing rate of 105 kg/hm 2, the colony and individual effect and better quality properties were best, hence it was the most suitable sowing rate.更多还原
