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 investigate the matching cultivation techniques of the national wheat trial Zhengmai 9962, the rational application rates of N, P2O5 and K2O in Zhengmai 9962 were studied using “3414” experimental design. The results showed that the application of nitrogen fertilizer and phosphate fertilizer had a good yield increasing effect in the south of Henan province. The yield was 44.22% and 11.56% more than the nitrogen deficiency and phosphorus deficiency areas, respectively, and only 2.51% increase with the application of potassium fertilizer. According to the quadratic equation model, the highest yield of N, P2O5 and K2O fertilizers were calculated as 206.01,128.28 and 89.18kg / hm2, respectively, and the best economic fertilizers were 178.57, 93.06 and 0.2 kg / hm2, respectively.
