摘要
以密度、氮素、磷素、钾素为参试因子,采用二次回归正交旋转组合设计,对蓖麻杂交新品种含油率综合农艺措施进行研究.结果表明，主要农艺措施对蓖麻含油率增减作用的大小依次为：氮素>钾素>磷素>密度.在相同或相似条件下蓖麻含油率大于50.63%的最佳实施方案为：种植密度以22302～24498株/hm2为适宜，氮素（纯N）122.76～147.96kg/hm2，磷素（P2O5）171.97～196.42kg/hm2,钾素（K2O）158.62～182.77kg/hm2为佳.
With the participant factors of density, nitrogen, phosphorus, potassium, the combination design of orthogo-nal gyration was used in this experiment. And discussion the comprehensive agronomic measures with new hybrid vari-eties. The results showed that the major agronomic measures on the rate of increase the oil of castor:nitrogen>potassi-um>phosphorus>density. Under the same or similar conditions, the best implementation of the program to achieve the oil is over 50.63%:it is best to plant with the density of 22302~24498/hm2, nitrogenous fertilizer(pure N)at 122.76~147.96 kg/hm2, phosphate fertilizer(P2O5)at 171.97~196.42 kg/hm2and potash fertilizer(K2O)at 158.62~182.77 kg/hm2.
