摘　　要：为探讨国审小麦新品种郑麦9962配套栽培技术,利用"3414"试验设计研究了郑麦9962氮(N)、磷(P2O5)、钾(K2O)肥合理施用量。结果表明:在豫南麦区,施用氮肥和磷肥的增产效果较好,分别比缺氮区和缺磷区增产44.22%、11.56%,施用钾肥仅增产2.51%。根据一元二次方程模型,求得N、P2O5、K2O的最高产量施肥量分别为206.01、128.28、89.18kg/hm2,最佳经济施肥量分别为178.57、93.06、0.2kg/hm2。In order to explore the cultivation technology suitable for new w heat cultivar Zhengmai 9962 which was approved by national standards ,a“3414”experiment design was used to study the application amount of nitrogen ,phosphorus and potassium fertilizer recommended for Zhengmai 9962 .The results showed that the nitrogen and phosphorus fertilization increased the grain yield by 44 .22% and 11 .56% ,respectively ,compared to no nitrogen and phosphorus application ,w hile the potassium fertilization increased 2 .51% than no fertilizer .Based on one variable quadratic model regression analysis ,the highest application rate of N ,P2 O5 and K2 O was 206 .01 kg/ha , 128 .28 kg/ha and 89 .18 kg/ha respectively ,and the most economic application rate of them was 178 .57 kg/ha ,93 .06 kg/ha and 0 .2 kg/ha respectively .
