| 中文摘要: |
| 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
（7 500～9 750 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、P2O5 67.05～108.15 kg/hm2、K2O
101.55～171.00 kg/hm2。 |
| 英文摘要: |
| In this experiment，quadratic orthogonal regressive rotation design of five factors were used to study
the effects of planting factors such as sowing date，density，nitrogen，phosphorus and potassium on the yield stability
of maize variety Xixiangban 99. The results showed that sowing time，planting density ，N application amount，P2O5
amount and K2O amount were significantly correlated with yield of maize. If Xixiangban99 reaches the stable yield
range of 7 500-9 750 kg/hm2，it needs to be sowed in March 4-11，and planting density is 51.8～57.9 thousand
plants per hectare，and N is 128.25～207.75 kg/hm2，P2O5 is 67.05～108.15 kg/hm2 and K2O is 101.55～171.00
kg/hm2. The ratio of N∶P2O5∶K2O is 1∶0.5∶0.8. This study provided a theoretical basis for large area production
of maize hybrids Xixiangban 99. |
