摘要：

为了探明小麦新品种‘云麦110’产量和品质相关性状对种植密度的响应,以该品种为试验材料,采用6个种植密度的单因素随机区组设计,考察该品种在不同密度下的产量与品质相关性状并进行方差分析。结果表明：种植密度对产量及产量三要素均影响显著;对第三、四、五、六、七叶期的茎蘖数均影响显著,但对八叶期的茎蘖数影响不显著;对籽粒周长影响显著,但对其余4个粒型性状影响不显著;对容重影响显著,但对其余8个品质性状影响不显著。当基本苗为270×104/hm2时产量最高(6435.00 kg/hm2),茎蘖消长最平缓,成穗率最高(25.39%),籽粒周长最大(18.07 mm),容重最高(798.00 g/L)。因此,小麦新品种‘云麦110’产量和品质相关性状对不同种植密度的响应较大,其中基本苗为270×104/hm2时该品种产量最高,产量三要素最协调,茎蘖消长最合理,株高适宜,且综合品质性状最好,适宜在该种植密度下推广种植。

Abstract:

This study aims to explore the response of yield and quality related traits of a new wheat variety ‘Yunmai 110’ to different planting densities. ‘Yunmai 110’ was used as the experimental material, and one factor randomized block design with 6 planting densities was adopted. The yield and quality related traits were investigated, and the variance analysis of different planting densities was conducted. The results showed that planting density had a significant effect on the yield and yield components. It also had a significant effect on the number of tillers at the third, fourth, fifth, sixth and seventh leaf stages, but it had no significant effect at the eighth leaf stage. Planting density had a significant effect on the grain perimeter of the variety, but it had no significant effect on the other four grain type traits. Planting density had a significant effect on the bulk density of the variety, but it had no significant effect on the other 8 quality traits. When the basic seedling density was 270×104/hm2, the yield was the highest (6435.00 kg/hm2), the growth and decline of stems and tillers of the variety was the most gentle, the highest spike rate was 25.39%, the largest grain perimeter was 18.07 mm and the highest bulk density was 798.00 g/L. Therefore, the yield and quality related traits of the new wheat variety ‘Yunmai 110’ have a great response to different planting densities. The variety can obtain the highest yield with the basic seedling density of 270×104/hm2, under which the three yield elements are the most coordinated, the growth and decline of stems and tillers are the most reasonable, the plant height is appropriate and the comprehensive quality traits are the best. ‘Yunmai 110’ is suitable to be popularized under this planting density.

Key words: ‘Yunmai 110’, yield traits, quality traits, planting density, growth and decline of stems and tillers
