摘　　要：以玉米为材料,研究氮磷钾不同运筹模式对其生理特性、品质及产量性状的影响。结果表明,氮磷钾不同运筹方式对玉米穗位叶叶绿素含量、硝酸还原酶活性、穗长、穗粗、品质以及产量都有影响,且在不同施肥水平下,不同氮钾基追肥比例对性状的影响不同。在施肥水平高的条件下,氮钾基追肥比例以7/3产量最高;在施肥水平中等的条件下,氮钾基追肥比例以6/4玉米产量最高;在施肥水平低的条件下,氮钾基追肥比例以5/5玉米产量最高。With corn as material,the influence of the physiological characteristics,quality and yield by the NPK different management mode were studied. The results show that the NPK different management mode had effect on the ear leaf chlorophyll content,nitrate reductase activity,ear length,ear coarse,yield and quality,and on traits in different base fertilizer proportion under different fertilizer levels. Under the condition of high,middle and low fertilizer levels,the maize yield was the highest on base fertilizer N K proportion 7 /3,6 /4 and 5 /5 respectively.
