为了给大麦‘花22’茬口安排提供适宜的播期、播量组合，试验采用二因素随机区组设计，研究了6个播期水平和5个播量水平对崇明地区大麦主栽品种‘花22’产量和产量构成因素的影响。结果表明：播期、播量显著影响‘花22’产量及构成因素，播期11月4日、播量112.5~150 kg/hm2的产量相对较高，均在7500 kg/hm2以上。同时，相同播期的单位有效穗随播量增加而递增，相同播量则随播期推迟而递减，穗粒数随播期推迟和播量增加呈递减趋势，千粒重随着播期的推迟呈递增趋势，而随着播量的增加递减。因此，结合上海崇明地区实际种植情况，‘花22’播种时间以11月4日—14日之间为宜，随着播期的推迟，产量呈下降趋势，播量以150 kg/hm2左右最佳，随播期推迟适当提高播量可以达到增产目的。

In order to provide cropping arrangement with the suitable combinations of sowing date and rate, filed experiment with 2 factors randomized block design investigated the effects of sowing date and sowing rate on yield and yield components of barley‘Flower 22’. The results showed that the sowing date and rate affected the yield and yield components of barley‘Flower 22’significantly. Sowed on November 4 with 112.5-150 kg/hm2 could obtain relatively high yield which more than 7500 kg/hm2. Meanwhile, the panicle increased with the increasing of sowing rate on the same sowing date, and dropped with the delay of sowing date with the same sowing rate; grain number decreased with the delay of sowing date and the increasing of sowing rate; grain weight increased with the delay of sowing date, and dropped with the increasing of sowing rate. Therefore, combined with the practical cultivation of Chongming Shanghai, the better sowing date of‘Flower 22’between November 4 to 14, the better sowing rate was about 150 kg/hm2, and sowing rate raised appropriately could increase the yield.
