| 摘 要： | 试验通过对黑农38和东农42不同比例混种群体的田间通风透光状况及植株叶面积指数的测定发现,与单一品种清种相比,黑农38和东农42以2:1的比例混种可以通过改善群体的通风状况和不同冠层的光照分配,促进光合产物的合成,改善光合产物的分配,提高有效花荚数目,显著提高大豆的产量。但由于混种后,收获的籽粒存在一定的差异,因此可根据产品用途选择清种或混种。

| Abstract: | Compare to single planting,the mixed planting of Heinong 38 and Dongnong 42 in ratio of 2:1 can improve ventilation conditions and the light distribution in soybean canopy,accelerate the synthesis of photosynthate,increase effective flowers and pods,and get the high yield.The single planting or mixed planting is choosed according to the use of the product because mixed planting will induce the seed inconformity. |
