摘要: 采用二次回归正交旋转设计试验方法,对不同生态区紧凑玉米新杂交种成单11号高产栽培综合农艺措施进行了研究。结果表明,(1)玉米产量与密度、氮肥、磷三因素存在真实的二次回归关系,回归方程的F1为0.89-5.08,F2为3.10-14.26;(2)三因素及其相互作用对产量均有一定影响,但不同地点其作用顺序不一致,边际效益不相同;(3)本文得出的成单11号高产栽培最优组合措施为:亩植3500-4000株,亩施有效氮10.0公斤左右,有效磷5.0公斤左右。

Abstract: The comprehensive agronomic practices for high yield of the new erect leaf type hybrid CHENGDAN 11 of maize were studied by using the orthogonal rotationd desing of quadratic regression in the different ecological regions. The results showed as follows:(1). thequadratic regression on yield with density, nitrogen and phosphorus was significant in maize, F1 of the regression equation was 0.89 to 5.08, F2 was 3.10 to 14.26;(2). each factor and its interaction affected yield to a certain extent, but the sequence of effects and marginal effect was not the same in different districts;(3) the optimum comprehensive practices for high yield of the hybrid were density of 3500-4000 plants, about 10.0 KG N available and about 5.0 KG P2O5 available per mu.
