| 摘 要： | 通过田间试验研究了种植密度对冬小麦籽粒灌浆特性、粒重和产量的影响。结果表明:种植密度对灌浆持续期没有明显影响,但对粒重和灌浆速率影响较大,低密度处理粒重最大,最大灌浆速率也最高。茎秆、叶片对籽粒的贡献率不同处理不同品种均为茎秆大于叶片;随种植密度的增加,穗粒数和千粒重减小,而中密度处理产量最高。

| Abstract: | The effects of different planting densities on the grain-filling characteristics,grain weight and yield of winter wheat were studied through field experiments.The results showed that planting density had not significant effect on grain-filling duration,while it had great impact on grain weight and grain-filling rate,winter wheat planted at low-density had the highest grain weight and maximum grain-filling rate.For different varieties in different treatments,the contribution rate of the stem to the grain was... |
