摘　　要：2004-2006年进行了鲜食大豆种植密度及其对相关农艺性状的影响研究,结果表明,早、中、晚熟品种适宜种植密度分别是24.0万株·hm^-2左右、21.0万株·hm^-2左右、19.0万株·hm^-2-21.0万株·hm^-2。种植密度对其相关农艺性状（分枝数、结荚数、百粒重）的影响是：结荚数〉分枝数〉百粒重,但密度对百粒重的影响不显著。Plant densities of fresh edible soybean and its effects on agronomic traits were studied from 2004 to 2006. The results indicated that different maturation period of fresh edible soybean enjoyed special plant densities. Plant densities of 24 0000 plant · hm^-2 , 21 0000 plant · hm^-2 and 19 0000- 21 000 plant· hm^-2 were suitable for early, middle and late cultivars, respectively. The effects of plant densities to pods were stronger than that of branches quantity, while effect of plant densities on 100-seed weight was not significant.
