夏玉米聊88-2综合优化栽培技术研究

STUDY FOR THE COMPREHENSlNVE PRACTICALTECHNIQUE ON SUMMER MAIZE HYBRID“LIAO 88-2”

根据二次回归正交旋转设计试验结果，建立了在聊城中肥土壤条件下密度、氮、磷、钾、锌肥和量五因子与紧凑型玉米聊８８－２产量关系的数学模型；筛选出了不同目标产量时各因子最佳水平范围；并各因顺子交应作了分析。

This paper dealt with the relation between grain yield of summer maize hybrid ' Liao 88 - 2” and its five relative factors including plant density , N , P2O5, k2O and zinc under the mid - fertility soil in Liaocheng Prefecture. A mathematical model had been es- tablished based on the experimental results of guadratic regression and orthogonal rota- tion design. The optimum rage for each factor had been estimated under the different target yield. The effect of every single factor had been analyzed as well.
