种植密度对不同玉米品种产量及籽粒灌浆的影响
Effects of Plant Density on Yield and Kernel Filling of Different Maize Varieties
摘要
Abstract
In order to explore the effects of plant density on the yield and yield components of maize, three high -yielding maize cultivars Zhengdan 958, Denghai 3719 and Jinhai 5 were used for this study in field with three plant density treatments, low density (52 500 plants per hectare), medium density (97 500 plants per hectare) and high density (97 500 plants per hectare). The results showed that plant density obviously affected the filling of kernels at different ear positions for all tested cultivars, and the kernels at top ear position were affected the greatest However, the kernel filling of Jinhai 5 was affected the least by plant density. The yield was affected significantly by the plant density for all tested cultivars. For Jinhai 5, the yield increased with the increase of density, but the other two cultivars Zhengdan 958 and Denghai 3719 reached the highest yield at the medial plant density. The yield of Jinhai 5 was the highest under all plant density conditions compared to the other two cultivars.关键词
