以大穗型（01-35、8355）、中间型[6200（8）、4133-2]和多穗型（988044、02-48）3种类型的超级小麦品种（系）为材料,研究不同播期与播量对不同类型品种（系）小麦穗数、穗粒数、千粒重和产量的变化。结果表明：大穗型品种最佳播期在10月15日,中间型、多穗型品种最佳播期在10月5日;播期对穗数的影响差别最高可达15%以上,对穗粒数、千粒重和产量的影响差别均在13%以下;播量对其各项指标的影响差别均在5%以下。3种类型品种小麦均以中、高密度播量较高,播期对超级小麦产量各构成因素的影响大于播量。
以大穗型（01-35、8355）、中間型[6200（8）、4133-2]和多穗型（988044、02-48）3種類型的超級小麥品種（繫）為材料,研究不同播期與播量對不同類型品種（繫）小麥穗數、穗粒數、韆粒重和產量的變化。結果錶明：大穗型品種最佳播期在10月15日,中間型、多穗型品種最佳播期在10月5日;播期對穗數的影響差彆最高可達15%以上,對穗粒數、韆粒重和產量的影響差彆均在13%以下;播量對其各項指標的影響差彆均在5%以下。3種類型品種小麥均以中、高密度播量較高,播期對超級小麥產量各構成因素的影響大于播量。

The experiment was conducted with three types super wheats,such as the large ear cultivars（01-35,8355）,the middle ear cultivars[6200（8）,4133-2] and the many ear cultivars（988044,02-48）.A study was made on the variation of ears,grains per ear,weight per thousand grains and grain yields.A conclution of the best seeding time and seeding quantity of different genotypes wheats was made.The results showed that the optimal seeding time of the large ear cultivars was on 15th October,the optimal seeding time of the middle ear cultivars and the many ears cultivars was on 5th October.The influence of seeding time on the ears was more than 15% at most,but the in fluence of that on the grains per ear,weight per thousand grains and output were under 13%.The influences of different seeding quantity on all kinds of indexs were under 5%.The output of three genotypes wheats was more through middle high density.Impact of the seeding time on the output facters of super wheat was greater than that of seeding quantity.
