摘要
[目的]为科杂2号在安徽沿江棉区大面积示范推广寻找高产高效栽培模式。[方法]采用4元2次回归正交旋转组合设计对科杂2号进行高产栽培试验,建立科杂2号皮棉产量与栽培密度、氮肥、磷肥和钾肥的函数模型,并对上述模型进行显著性测验。[结果]最优农艺措施组合：密度为21 606~22 394株/hm2,氮肥（N）为234.3~266.1 kg/hm2,磷肥（P2O5）为85.2~114.8 kg/hm2,钾肥（K2O）为186.0~214.80 kg/hm2。[结论]该研究建立的数学模型具有实际意义,可作为科杂2号高产栽培技术模式应用于生产。
[Objective] The aim was to study high-yielding cultural techniques of keza 2 cotton for large area demonstration and popularization in changjiang river cotton areas.[ Method]Using the four elements quadratic regression orthogonal rotational combination design in this experiment,high-yielding cultural techniques of keza 2 was studied.The mathematical model was set up,and its significance test was conducted.[Result]The study showed that the optimal agronomic measure was density of 21 606-22 394株/hm2,N of 234.3-266.1 kg/hm2,P2O5 of 85.2-114.8 kg/hm2,K2O of 186.0-214.8 kg/hm2.[Conclusion] The mathematical mode was used in production as high-yielding cultural techniques of keza 2.
