摘　　要：高油玉米生产上要考虑其经济产量和果穗商品质量,对高油115玉米进行不同施肥和栽培密度的试验,结果表明:密度为5 2 5 0 0株/ hm2、施肥量为N36 0 kg/ hm2、P2 O512 0 kg/ hm2、K2 O180 kg/ hm2时的玉米产量、含油率、蛋白质含量和氨基酸含量等综合性状最好,而淀粉含量较低,为当地条件下适宜的栽培密度和施肥水平。Considering of economical output and commodity in production of highoil maize, fertilization and planting density in different levels were tested in culture of the maize variety 115. The results showed that while the planting density was 52500/hm 2, and the fertilization was N 360kg/hm 2, P 2O 5120kg/hm 2 and K 2O 180 kg/hm 2, the comprehensive trait of the variety, including the grain yield, the percentage of oil content, the protein content and the aminoacid content was the highest; and the starch content was quite low, which is adapted to the planting density and fertilization level at the local condition.
