采用2因素裂区试验设计,进行了主区为小麦品种、副区为氮用量水平,设置不施肥对照、5个氮素用量水平的6处理田间试验.结果表明:在不同氮水平条件下,小麦籽粒的产量、蛋白质和淀粉含量以及加工品质指标均存在显著性差异.3个小麦品种的土壤基础肥力产量、最高产量及其施氮量的差异显著,但氮肥能提高的最高绝对产量都相当.同时,依据施氮水平与产量试验数据,用二次多项式模拟得到小麦氮肥产量效应方程和复相关系数.鄂麦18:y=-0.059x~2+30.209x+3165.7,R~2=0.965 8~(**);鄂麦23∶y=-0.069 x~2+32.856x+2 321.7,R~2=0.9963~(**)和郑麦9023∶y=-0.070x~2+31.912x+3 947.4,R~2=0.965 8~(**).

The field experiment with two factors of split area,six treatments using no fertilization as control,five levels of nitrogen and three varieties of wheat was designed and carried out.The results showed that there was significant difference among seed yields,contents of protein and starch,processing quality index of three varieties of wheat at different nitrogen levels.There was marked variation among yields of wheat in soil basic fertility and dose of nitrogen applied with the highest yields of three varieties of wheat,but the highest yields increase of nitrogen are nearly equal.Correlation between wheat yields and rates of nitrogen dosage was calculated.The double interrelated coeffidents of Emai 18,Emai 23 and Zhengmai 9023 ale y=-0.059x~2+30.209x+3 165.7,R2=0.965 8~(**);y=-0.069 x~2+32.856 x+2 321.7,R~2=0.996 3~(**);Y=-0.070 x~2+31.912x+3 947.4,R~2=0.965 8~(**),respectively.
