| 摘 要： | 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。

| Abstract: | The experiment was conducted with three types super wheats,such as the large ear cultivars(01-35,8355),the middle ear cultivars6200(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 ... |
