摘　　要：通过不同施肥模式对比试验,研究玉米生长发育、需肥特性、土壤养分及产量的变化规律,构建吉林中部玉米高产施肥模式。研究结果表明,玉米高产施肥模式:底肥深施优质有机肥,无机肥N、P2O5、K2O施肥水平分别为350 kg/hm2、150 kg/hm2和190 kg/hm2,补充施中、微量元素Zn、S、Mg、B、Mn等,采用底肥、口肥和分次追肥的施肥方式,玉米生育中后期不但追施氮肥,还要追施磷、钾肥。Change rule of growth and development, fertilizer requirement characteristics, soil nutrition and yield of maize were studied through comparison of ditterent fertilization models.And me fertilization model of high yield in middle Jilin province was constructed, i.e., organic fertilizer needed to be buried deeply as base fertilizer; application standards of N, P2O5, K2O were 350 kg/hm^2, 150 kg/hm^2 and 190 kg/hm^2, respectively; trace elements Zn, S, Mg, B and Mn needed to be complementary. N, P and K need to be applied by the pattern of base, seed-fertilizer and dressing. In the middle and late period of maize growing, not only N should be applied, P and K are also needed.
