chinois. 以农大108、四单19、龙单26、丰禾10和东农250为材料，在施氮（N. _┖筒皇┑_N0）两种条件下对参试品种的干物质、产量和品质性状变化进行了分析。结果表明：与氮胁迫相比，施氮能明显提高玉米干物质生产量、子粒产量、子粒粗蛋白含量和淀粉含量，但品种间存在明显的差异。农大108和四单19干物质积累能力强，但农大108没有表现出产量优势。[著者文摘]
Afficher plus [+] Moins [-]anglais. Nitrogen is a large necessary element in maize development, and the nitrogen is an important factor in deciding the yield and quality of maize production. The purpose of this study was to analyze dry matter, yield and quality changes of character in five spring maize （Zea mays L.） cultivars, Nongdal08, Sidanl9, Longdan26, Fenghe10 and Dongnong250 under N input （N. __and N stress （NO） conditions. The results showed that with N0, N. _can significantly improved the dry matter production of maize, grain yield, grain and crude protein content of starch content, but significant differences existed between different varieties. Nongda108 and Sidan19 had a stronger ability to accumulate dry matter, but Nongda108 showed no yield advantage.
