| 摘 要： | 试验研究重茬对大豆株型的影响。结果表明:重茬对大豆株高、分枝数和主茎节数的影响与正茬相比均不显著,重茬能显著增加大豆的结荚高度。重茬使大豆的叶面积指数降低,叶面积指数的减小幅度与结荚习性有关,亚有限性结荚习性大豆的减小幅度较大,有限结荚习性大豆则相对较小。重茬较正茬大豆的叶绿素含量降低,苗期和鼓粒期降低较明显,光合速率重茬较正茬也有降低的趋势。

| Abstract: | The purpose is to study the influence of successive cropping on plant-type of soybean varieties from Liaoning Province.The results show that successive cropping have a slight effect on plant height,branch number,and node number of soybean varieties.Successive cropping have a significant effect on height of podding of soybean varieties.The leaf area index of soybean of successive cropping decreased in comparison with that of normal rotation,the decrease is relative to bearing habit,semi-determinate soybean varieties have a bigger decrease,determinate growth habit soybean varieties have a relatively smaller decrease.Obviously lower chlorophyll content of soybean at seedling and filling,The rate of photosynthesis of soybean varieties decreased under successive cropping. |
