摘 要: | 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135 kg/hm2的产量9 772.5 kg/hm2为最高,此后播期每推迟1 d,产量下降56.35 kg/hm2,但迟至12月7日(大雪)播种,仍可保持产量6 765.0 kg/hm2。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1 d,应相应增加播量5.8 kg/hm2,以密补晚,可挽回晚播而减产的损失9.05 kg/hm2。

Abstract: | 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/hm2 could get the highest production to 9 772.5 kg/hm2.After that,the yield would reduce 56.35 kg/hm2 delaying one day.Even late to December 7 th(great snow day),the yield could reach 6 765.0 kg/hm2.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/hm2,so as to recover yield by 9.05 kg/hm2 from the loss caused by late seeding. |
