摘　　要：采用二次饱和－Ｄ最优设计的方法，研究Ｓｒ（ＮＯ３）２（ｘ１）、ＫＨ２ＰＯ４（ｘ２）和Ｎａ２Ｂ４Ｏ７·１０Ｈ２Ｏ（ｘ３）叶面喷施对秦油２号油菜的产量效应，获得回归方程：ｙ＝２４７．４８５＋７．００４８ｘ１＋２．２９２４４ｘ２—９．８２６４６ｘ３—０．２５３５ｘ１ｘ２—１３．８５２４ｘ１ｘ３：—３．３７４７５ｘ２ｘ３＋２７．０５７５Ｘ２１—１６．３０３６ｘ２２—８．７６７８ｘ２３结果表明Ｓｔ（ＮＯ３）２。有明显的增产作用．ｘ１ｘ３的交互作用（效应）最大．通过计算机模拟．其最佳因子组合为Ｓｒ（ＮＯ３），０．１％、ＫＨ２ＰＯ４０．３％和硼砂０．０１％，预计产量可达２９６．４６ｋｇ／６６７ｍ２．Leaf spraying Sr(NO3)2(x1)KH2PO4(x2)and Na2B4O7.10H2O(x3) were studied on yield effect in rape F1 hybrid cultivar Qinyou No.2'.with method of quadritic saturation Dbest design in this paper.Regress equation was obtained.i.e:y=247.485+7.0048x1+2.29244x2 9.82646x3 0.2535x1x2 13.8524x1x3 3.37475x2x3+27.0575x21 16.3036x22 8.7678x23The result indicated that there was an obvious increase of yield with leaf spraying x1 and that alternate effect of x1x3 was the largest.The optimum factor combination was Sr (NO3) 20. 1%.KH2PO4 0.3% and Na2B4O7.10H2O 0.01% by computer imitation.It's estimated yield is 296.46kg/667m2.
