摘　　要：探讨种植密度对向日葵产量性状指标的影响,可以为向日葵生产上的合理密植提供依据。选用经葵809B作试验材料,采用随机区组设计法,进行了不同种植密度对向日葵农艺性状及产量的影响研究。结果表明,随着种植密度增加,盘径逐渐减小,产量有所增加,株高和百粒重先增加后减少,在密度37 500株/hm^2时商品性最好。因此,选择适宜品种并结合品种自身特性,合理增加种植密度才能提高向日葵产量。In order to provide the basis for sunflower production,taking Jingkui 809B as test material,using randomized block design method,theeffects of planting density on yield and agronomic characteristics of sunflower were studied.The results indicated that disc diameter reduced gradually;yield increased,plant height and 100-kernel weight increased first and then decreased with planting density increased.The commodity was the best inthe density of 37 500 plant/hm^2.It could draw the conclusion that a reasonable increase in planting density could promote the yield of sunflowerproduction with choosing suitable varieties.
