Abstract
采用五元二次正交旋转组合设计方法,研究不同播种期、种植密度、氮素水平、磷素水平、钾素水平对玉米新品种喜相伴99产量的影响,以找出不同栽培产量水平的优化栽培措施方案.结果表明,播种期、种植密度、施N量、施P2O5量、施K2O量等与玉米产量回归相关显著,喜相伴99高产(7500~9750 kg/hm2)栽培方案为:3月4~11日播种,种植密度5.18万~5.79万株/hm2,按N、P2O5、K2O比例约1:0.5:0.8施肥,施肥量为纯N 128.25~207.75 kg/hm2、P2O567.05~108.15 kg/hm2、K2O 101.55~171.00 kg/hm2.
