| 摘 要： | 以矮秆蓖麻CSR268为材料研究不同群体密度对蓖麻各性状指标的影响，结果表明群体密度对CSR268株高、株穗数、穗粒树等产量性状及叶面积系数、净同化率等均有不同程度的影响。在29083株/hm^2-47451株/hm^2群体密度条件下，以38267株/hm^2产量最高（2208.8kg/hm^2），（2108.8kg/hm^2），其次为42859株/hm^2，且显著高于其它群体密度。

| Abstract: | Take he dwarfed castor CSR268 as materials to study the effect of different population density to the every characters of castor.The result indicated that the population density has many effects in varying degrees on the high of CSR268,the number of the plant,the plant yield characters,the coefficient of the leaf square and the net assimilation ratio,and so on.Under the population density of 29,083 /hm2-47,451/hm2 condition,processes 3(38267/hm2) the yield to be the highest,next is 42859/hm2,the yield respectively is 2208.8 kg/hm2,2108.8 kg/hm2,and the density is significantly higher than other groups. |
