摘　　要：研究了在高产条件下,不同行距配置、密度对奶花芸豆群体田间小气候变化、冠层结构、光能分布与利用特性及产量构成的影响.结果表明在适宜的群体密度下,通过扩大行距,减小株距,有利于优化群体结构,显著影响小气候因子在群体中的分布,改善个体生育状况和群体通风透光条件,使产量构成因素实现最佳配置,充分利用地力和空间,从而获得最佳产量.在实验条件下,密度15000株/hm2,行距60cm或采用80+40cm宽窄行、株距10～15cm是奶花芸豆理论上的田间最佳分布的配置.Effects of different spacing form,density on structure of population,light distribution and yield of Phaseolus vulgaris were studied under the high yielding condition. The results indicated that there are beneficial to achieve appropriate population structure and thereby adjusting micro-climate by to enlarge space in row and reduce plant space in suitable planting density. Will improve the yield components, enhance the sand pace and land, and give high yield, in the experiment the most suitable density was 150000plants/ha, the best space in row was 60cm and 80＋40cm, the best plant space was 10-15cm.
