摘　　要：试验以本育9、平安18、丰禾10、四单19为试验材料,研究了不同氮素用量对春玉米淀粉积累的影响。结果表明,春玉米总淀粉含量、支链淀粉含量、直链淀粉含量在籽粒灌浆过程中均呈"S"形曲线变化趋势;对于春玉米淀粉积累而言,N200处理是最佳处理。This experiment utilized Benyu 9, Ping＇an 18, of nitrogen application on the accumulation of starch in spring Fenghe 10, Sidan 19 as material, studied the effect maize. The results showed that total starch content, amylopectin content and amylase content in spring maize changed as “S” curve. N200 was the best treatment to accumulation of starch in spring maize.
