摘要
采用小区试验,研究了不同施氮水平对杂交中稻红莲优6号产量和品质的影响。结果表明,合适的施氮量(公顷施纯氮210 kg)可以增加群体叶面积指数、提高光合速率、改善群体光环境,最终达到增加产量和改善品质之目的。
The effeets of nitrogen fertilizer levels on yield and quality in middle-season hybrid rice Honglianyou No,6 were studied in plot experiments. The result showed that appropriate nitrogen fertilizer (N210kg·hm^-2) could raise yield and improve quality by increasing canopy leaf area index, raising net photosynthesis rate and improving the light environment.
