摘　　要：采用"3414"完全方案试验,对河套灌区玉米一穴双株高密度栽培氮、磷、钾肥最佳施用量进行研究。通过试验证明,氮、磷、钾肥的足量配合施用对一穴双株高密度栽培玉米的产量影响较大。氮、磷、钾肥的综合效应为78.7%,说明足量氮、磷、钾肥配合施用,才能发挥肥料的最大效应。氮、磷、钾三种肥料以氮肥效应最大,为52.4%,其次是磷肥,为36.4%。初步确定河套灌区玉米一穴双株高密度栽培经济最佳施肥量N为393.75 kg/hm^2,P_2O_5为291.90 kg/hm^2,K_2O为93.15 kg/hm^2。In this study, the optimal nitrogen （N）,phosphate （P） and potassium （K） fertilizers dosage of corn planting under high-density planting condition （double plants in one point） was studied in Hetao irrigation district by using ＂3414＂ fertilizer experiment method. The results showed that the combination of N ,P, K fertilizers obviously influence the yields of corn under high-density maize planting condition （double plants in one point）. The comprehensive effect of N,P and K fertilizers was 78.7% ,which indicated the effects of fertilizers can be exerted mostly under coordination condition of enough N,P,K fertilizers. The N fertilizer was the highest effect （52.4%） and P fertilizer was higher （36.4%） among the three fertilizers of N,P,K. Based on the preliminary result, the optimum economy fertilizers dosage of corn planting under high- density planting condition （double plants in one point） in Hetao irrigation district was：N was 393.75 kg/hm2, P205 was 291.9 kg/hm2,K20 was 93.15 kg/hm2.
