摘　　要：以粮饲兼用型玉米主栽品种龙单26为试验材料,研究了不同氮、磷施用量对玉米产量和品质的影响。结果表明:不同氮、磷水平对玉米籽粒产量和品质影响较大,在施肥量为N160 kg.hm-2、P2O575 kg.hm-2、K2O50 kg.hm-2时,籽粒产量、淀粉含量和赖氨酸含量最高,在施肥量为N160 kg.hm-2、P2O5100 kg.hm-2、K2O50 kg.hm-2时,蛋白质和脂肪含量最高。The effects of different nitrogen and phosphorus application on grain yield and quality of compact corn Longdan 26 were studied. The results showed that a significant difference between grain yield and quality of corn at different levels of ni trogen and phosphorus application. Under this experiment condition,the suitable application amount of N.P2O3 and K2O was respectively 160 kg·hm^-2 . 75kg·hm^-2 and 50 kg·hm^-2, the most amount of grain yield,starch and lysine was observed. The suitable application amount of N.P2O3 and K2O was 160kg·hm^-2, 100 kg·hm^-2 and 50 kg·hm^-2. respectively, the most amount of grain protein content,corn gain oil content was observed.
