不同群体密度对绿豆农艺性状和产量的影响

本文探讨了不同密度处理绿豆的形态特征、产量的形成,以及这些指标与密度的相关性。结果表明：随着种植密度的增加,绿豆植株形态特征有较大的变化。具体表现在：随密度增加,绿豆株高逐渐增加,基部节间茎粗逐渐下降,且这两个性状对密度的反应敏感,与密度相关差异显著。密度对绿豆有效分枝数、底部有效分枝高度的影响均达到显著水平。产量构成因素中,密度对单株荚数、单株粒重、百粒重的影响均达到显著水平。

Effects of Different Population Densities on Yield and Agronomic Characteristics of Mung Bean

With the methods of crop population physiology,the effects of different population densities on growth,development and yield of mung bean as well as the relationship between these indexes and density were studied.The results showed that the morphology indexes of mung bean plant changed significantly with planting density increasing：the plant height showed increasing trend,while the stem diameter of the basal intemode were gradually decreased.And these two indexes were sensitive to the density.The effects of planting densities on valid branch number and the height of the first branch had reached significant level.In the yield components,the effects of planting densities on the pod number per plant,the grain weight per plant and the hundred grain weight had achieved significant level.
