摘　　要：研究为四因素三水平试验,以鲁单50为供试品种,比较在氮磷钾比例相等条件下,控释肥料(CRF)用量比例从全量减少到2/3或1/2时对玉米生产效应的影响。结果表明,施肥处理产量比CK0增幅15.04%～37.67%,各CRF用量与对照相比产量增幅为1.98%～19.02%,且3类CRF均在2/3用量时产量最高;B(2/3)、A(2/3)、C(1/2)这3个处理的粗脂肪、游离氨基酸及蛋白质总量均明显高于对照,其余与对照含量接近或稍低。This experimental design at 4 factors and 3 levels. The variety of maize was LD 50.The intention of this research was that when the proportion of N, P2O5, K2O were equal, compared different dosages（including as much as CK, 2/3CK, 1/2CK） of controlled-release fertilizers（CRF） in influencing the yield and efficiency of maize. The results showed that the maize yield of fertilization treats increased by 15.04% - 37.67% than CK0, and increased by 1.98% - 19.02% than CK. Above of all, the yield of 2/3 dosages of CRF was highest. The results indicated that B（2/3）, A（2/3） and C（1/2） were obviously better than CK in the content of EE, dissociated AA and Pr, other treatments were near or a bit lower than CK.
