摘要
试验以杂交玉米黔单24为试材,采用四因素五水平二次回归正交旋转组合设计,研究种植密度及氮磷钾肥施用量对玉米产量的影响.研究结果表明,在黔西南地区杂交玉米黔单24单产达到730.27kg/667m2以上的最佳高产栽培措施为：种植密度4170～4294株/667m2,氮肥22.78～25.7kg/667m2,磷肥13.75～16.25kg/667m2,钾肥9.335～11.005kg/667m2.
Quadratic regression orthogonal rotational and sing＇e--factor randomized biock design were adopted, and effects of planting density, fertilization and seed coating on main agronomic traits and yied were researched in order to support techniques for high--yield cultivation o{ hybrid maize cultivar, ,Qiandan24. The results showed that the optimized cultivation techniques of Qiandan 4 for high--yield were that the planting density, N fertilizer, P fertilizer and K fertilizer were 4t70--4294 plants/667 ms ,22. 78--25.7 kg/667 ms ,13. 75--16.25 kg/667 ms and 9. 335--11. 005 kg/667 m2 , respectively.
