摘　　要：以皖麦38为材料,研究了不同密度和氮肥基追比例互作对强筋小麦群体质量的影响。结果表明:密度相同时,适当增加拔节期追氮比例有利于群体质量的提高;氮肥基追比例相同时,密度减少,单株营养条件明显改善,分蘖成穗率显著增加,叶面积系数减小,株高降低,干物质积累减小。12个互作处理中,密度180万苗/hm2、基追比例5∶5处理的干物质积累量最高,产量达到7826.08kg/hm2。With wanmai38 as material. The paper studied the effects of different density and Nitrogen fertilizer applied ratio on the groups quality of high gluten wheat. The result showed with the same sowing quantity, appropriately increasing the pro-portion of nitrogen recovery in jointing stage was conducive to the improvement of population quality ; the same nitrogen fertilizer applied ratio, decreasing sowing quantity had markedly improved Nutrition condition of individual plant noticeably, let individual plant healthy and strong, increased tillering and spike rates significantly, reduced the leaf area index, plant height, reduced dry matter accumulation. Different seeding rate conditions, the recovery ratio based on Wanmai38 dry matter accumulation were inconsistencies, sowing quantity and nitrogen fertilizer applied ratio existed interaction effects, 12 interacted treatments, dry matter accumulation of 180kg/hm^2 broadcast, nitrogen fertilizer applied ratio of five ： five of was the highest, the maturation period does matter accumulation amounts reach 7826. 08kg/hm^2, was conducive to production.
