摘　　要：采用二次正交旋转组合设计,在N、P2O5、K2O施用量分别为102～276kg/hm2、13.8～138kg/hm2、8.6～138kg/hm2条件下,探讨N、P、K对高淀粉玉米华单208产量和营养品质的影响。结果表明,对玉米产量,N的影响为开口向下的二次曲线,K为正线性关系,K与N存在负向互作;对粗淀粉含量,N的影响为开口向上的二次曲线,存在最低含量的施N量,P、K则为负线性关系,P与K存在负向互作;对粗脂肪含量,N、K的影响均为开口向下的二次曲线,P则为负线性关系,P与K存在正向互作。Adopting the method of orthogonal rotatable central composite design, discussing the impact of N, P, K on the yield and quality of corn-Huadan208 in the application volume that N N 102 - 276 kg/ha, P2O5 13.8 - 138 kg/ha, K2O 8.6 - 138 kg/ha. The results showed that on the corn yield, under the influence of the N, that was a quadratic curve open downward, K was for positive linear correlation, between K and N, there was a negative interaction; on the starch content, the impact of N was a quadratic curve open upward, and existed the lowest volume of N, P and K was negative linear relationship, between P and K lies a negative interaction; on the fat content, both under the influence of the N and K were quadratic curves open downward, P is negative linear relationship, between P and K existed positive interaction.
