摘　　要：以密度、氮素、磷素、钾素等为参试因子，采用四元二次回归正交旋转组合设计，对蓖麻杂交新品种通蓖6号高产优质栽培的综合农艺措施进行了研究．结果表明，主要农艺措施对蓖麻产量增减作用的大小依次为：密度〉钾索〉磷素〉氮索．在相同或相似条件下通蓖6号产量大于2052．86kg／hm^2的适宜农艺措施组合为：种植密度以23214-24786株／hm^2为适宜，氮肥（纯N）99．9～169．2kg／hm^2，磷肥（P205）131．63～168．37kg／hm^2，钾肥（K2O）136．27～163．72kg／11m^2为佳．The orthogonal gyration combination design was used in this experiment with plant density, and N, P and K rates as the influencing factors. Under the ecological conditions of the trial location, the following combination of the factors ensured a stable yield of 〉 2052.86 kg/hm^2 ： plant density 23214 - 24786 plants/hm^2, nitrogenous fertilizer at 99.9-169.2 kg N/hm^2, phosphate fertilizer at 131.63 - 168.37 kg P2O5/hm^2and potash fertilizer at 136.27 - 163.72 kg K20/hm^2. Plant density showed the greatest effect on castor yield, followed in order by potash, phosphate and nitrogen.
