| 摘 要： | 为研究苏南沿江稻麦两熟地区不同水稻收获期对后茬小麦产量影响,进行了小麦不同播期播量试验.结果表明不同播期（10月25日-11月29日）处理产量差异极显著,随着播期推迟不同单产呈下降趋势.不同播量处理（150×104,225×104,300×104,375×104,450×104/hm2）间产量差异不显著,在相同播量水平下（300×104/hm 2）随着播期推迟产量不断下降.苏南沿江地区小麦最佳的播种时间为10月25日-11月15日,最佳基本苗为150×104～225×104/hm2.

| Abstract: | In order to study the difference of harvesting time of wheat and rice in southern bank of Yangtze River affects the yield of wheat stubble, sowing experiment were carried on repeatedly at different date. It was found out that harvest changed significantly with sowing time between October 25th and November 29th. The delay in sowing time resulted in decreasing yield per hectare. No significant difference was detected among differently treated sowing experiment （150 ×104, 225 ×104 , 300 ×104, 375×104 and 450 ×104/hm2 , respectively）. The best sowing period for wheat in southern bank of Yangtze River is from October 25th to November 15th, with the best basic seedlings were 1.5 million to 2. 25 million hills per hectare. |
