摘要:
为了指导小麦生产，加速小麦新品种的利用和推广，以长麦251为试材，研究了不同行距和播期对长麦251生长特性的影响。结果表明：不同行距对籽粒产量及其构成因素均有显著影响，16.5 cm窄行产量最高，19.8 cm行距次之，23.1 cm行距产量最低。随播种期的推迟全生育期天数呈减少趋势，籽粒重量呈降低趋势。晚播种小麦在一定范围内茎秆抗倒性能较高。9月25日播种的籽粒产量最高，较易发挥长麦251的产量潜力，过晚播种对籽粒产量不利。
Abstract:
In order to guide the production of wheat，speed up the use and promotion of new wheat varieties,taking Changmai 251 as experimental material,effect of row spacing and sowing time on the growth characteristics of wheat Changmai 251 were researched.The results showed that different row spacing had a significant influence on wheat yield and its components,suitable row spacing was 16.5 cm,its yield was the highest,19.8 cm was second,yield of 23.1 cm was minimum.With the seeding time delayed the whole growth period showed a trend of decrease;grain weight showed a trend of decrease.Lodging resistance of wheat stalks was the higher within a certain scope of late sowing.Grain yield of sowing on September 25 was the highest,easy to play yield potential of Changmai 251,late sowing was bad for going against the grain yield.
