摘要
通过对通蓖7号、通蓖9号两品种进行了5个种植密度的二因素随机区组试验设计,研究了种植密度对两品种667m2产量及全株籽粒含油量的影响.结果表明:两品种667m2产量随种植密度的加大先增加后减小,且呈抛物线变化;通过各自的回归方程得出通蓖7号、通蓖9号667m2最高产量时的密度分别为1594、1588株/667m2;在一定种植密度范围内,两品种籽粒含油量随种植密度的增加而升高.
According to the 5 levels planting density experiment of TongBi 7 and TongBi 9,studing the effect of planting density on yield per 667m2 and whole plant seeds oil content of the 2 varieties. The results show that： 2 varieties yield per 667m2 increas first and then decreases with the increases of planting density, as parabola; through the regression equation obtain that the maximum yield of TongBi 7 and TongBi 9 while the respective density is 1594, 1588 plants per 667m2; in a certain density range, seed oil content of the 2 varieties increase with increase of planting density.
