摘　　要：适量增施氮肥能促进淮稻9号分蘖和个体发育,有利于高产群体的形成,增加抽穗期至成熟期的干物质积累量,穗多穗大产量高。增加前期施氮比例可有效增加淮稻9号单位面积有效穗数。Appreciate application of nitrogen fertilizer could accelerate tillering and individual development of Huaidao 9, and was beneficial to form high-yielding population, increase dry matter accumulation between heading and maturity, and realize high yield with more and bigger panicles. Increase of nitrogen application ratio at early stage was able to promote effective panicles per unit area of Huaidao 9.
