| Abstract: | 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. |
