| 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。

| Abstract: | Change rule of growth and development,fertilizer requirement characteristics,soil nutri-tion and yield of maize were studied through comparison of different fertilization models.And the fertil-ization 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/hm2,150 kg/hm2 and 190 kg/hm2,respectively;trace elements Zn,S,Mg,B and Mn needed to be complementary.N,P and K need to be applied b... |
