以半冬性小麦新品种百农160为研究材料,分两个年度采用播期、播量单因素及两因素互作裂区试验设计,分析不同播期和不同播量对百农160产量及产量三要素的影响。结果表明：百农160的千粒重不受播期、播量影响,但群体、穗粒数、产量受播期、播量的影响均达显著或极显著水平。百农160适宜早播,最佳播期在10月10日前后；适宜播量为270~360万/hm2基本苗。在播期播量互作条件下,百农160适宜播期仍为10月10日前后,适宜播量控制在315万/hm2基本苗左右,产量最高；若因播期推迟,应适当增加播种量保障群体、提高产量,10月20日前后播种,播量增加至360万/hm2基本苗为宜。

Semi winter new wheat variety Bainong160 was selected as experimental material,two years of single factor and two factors interaction split-plot experiment design were carried out to study the effects of sowing date and seeding rate on yield and its three factors of Bainong160.The study on the two years ’ sowing date and seeding rate single factor and two factors interaction of Bainong160 indicated that the 1000-grain weight of Bainong160 was not affected by the sowing date and seeding rate,while the population,grain number per spike and yield were highly affected by the sowing date and seeding rate.Bainong160 was suitable for earlier sowing,the best sowing date should be around October 10th;the highest yield was obtained when the seeding rate was increased to (270~360)×104 basic seedling per hectare.Under the control condition of sowing date and seeding rate,Bainong160’s suitable sowing date was around October 10th,the suitable seeding rate was around 315×104 basic seedling per hectare;if the sowing date was delayed to the middle and last ten-day periods of October,the seeding rate should be increased appropriately to increase the population and the seeding rate should be increased to 360×104 basic seedling per hectare.
