摘　　要：[目的]为筛选毕豆2号的最佳栽培密度。[方法]2006～2008年,在贵州毕节分别选择德沟、赫章双坪、何官屯作为3个试点,设置6组处理,测定各项指标。[结果]随着栽培密度的增加,株高、底荚高度和节间长度均随之增加,主茎节数、分枝数、茎杆重量均减小,叶面积指数呈上升趋势,单株荚数、粒数和粒重逐渐减少。[结论]处理④为最佳栽培密度,其产量最高,达2 982.5 kg/hm2。[ Objective ] The study aimed to choose the best planting density of Bidou No. 2. [ Method ] From 2006 to 2008, took Degou, Hezhangshuangping, Heguantun in Bijie of Guizhou as three test locations, set six treatment groups, and determined all the indexes. [ Result ] The plant height, height of the bottom pod and internode length increased as density increased, meanwhile, main stem nodes, branch number, stalk weight decreased, and the pods number per plant, grain number and grain weight gradually decreased. [ Conclusion ] Treatment ④ was the best planting density, and the highest yield reached 2 982.5 kg/hm^2.
