不同播期与播量对怀川916小麦产量的影响研究结果表明，怀川916小麦以10月8日（寒露）播种、播量135kg／hm^2的产量9772．5kg／hm^2为最高，此后播期每推迟1d，产量下降56．35kg／hm^2,但迟至12月7日（大雪）播种，仍可保持产量6765．0kg／hm^2。实践证明，该品种不仅是早、中茬种植的高产、稳产、早熟优质的小麦品种，也是适合晚茬种植的稳产保收的良种，随着播期每推迟1d，应相应增加播量5．8kg／hm^2，以密补晚，可挽回晚播而减产的损失9．05kg／hm^2。

Effects of different sowing time and seeding quantity on yield of Huaichuan 916 wheat were studied. Results showed that Huaichuan 916 wheat should be seeded on October 8 th (cold dew), seeding 135 kg/hm^2 could get the highest production to 9 772.5 kg/hm^2. After that, the yield would reduce 56.35 kg/hm^2 delaying one day. Even late to December 7 th (great snow day),the yield could reach 6 765.0 kg/hm^2. It's proved by practices that this variety is not only high yield,stable yield and early-ripe kind of wheat to early and middle time wheat, but also suit to late wheat variety to get stable yield. With each day delay, seeding quantity should increase 5.8 kg/hm^2,so as to recover yield by 9.05 kg/hm^2 from the loss caused by late seeding.
