摘　　要：为合理使用肥料,提高玉米品质,以极早熟玉米新品种边单3号为试验材料,在6个氮素用量和6个磷素用量条件下,研究氮磷肥用量对边单3号品质的影响。结果表明:玉米籽粒的蛋白质、脂肪、淀粉和赖氨酸等含量的变化均受氮素和磷素用量的影响,蛋白质、淀粉及赖氨酸的含量受氮素的影响较大,而籽粒脂肪的含量受磷素的影响较大。To reasonably use fertilizers, improve maize quality, extremely early maturing maize varieties Biandan No. 3 was taken as material, the amount of nitrogen and phosphorus fertilizer Biandan No. 3 quality was studied under six nitrogen application and six phosphorus dosage conditions. The results showed that the protein, fat, starch, lysine content of maize grain were affected by application of nitrogen and phosphorus. Nitrogen had larger effect on grain protein, starch and lysine content,phosphorus had larger effect on grain fat content.
