摘　　要：[目的]研究不同垄距对广薯87藤叶和鲜薯产量的影响。[方法]以食用红心甘薯新品种广薯87为研究材料,在种植密度为6万株/hm^2的情况下,研究5个不同垄距(75、80、85、90、95 cm)处理对甘薯藤叶和鲜薯产量的影响。[结果]随着垄距的增大,藤叶产量也逐渐上升;在95 cm垄距处理时,藤叶产量达最大值,为12 656.3 kg/hm^2。因此,可通过适量加大垄距的宽度来提高藤叶产量。随着垄距的增大,鲜薯产量逐渐上升;当垄距为90 cm时,鲜薯产量达最大,为34 875.0 kg/hm^2。但垄距达95 cm时,产量反而开始降低。[结论]综合考虑,在西南丘陵地区甘薯机械化起垄时,垄距为90 cm时广薯87能获得较为理想的产量。[ Objective ] To research the effects of row spacing on the cane leaves yield and fresh tuberous roots yield of Guangshu 87. [ Method ] With Guangshu 87 as the raw materials, we researched the effects of five row spacing treatments （75,80,85,90,95 cm） on the cane leaves yield and fresh tuberous roots yield under the planting density of 60 000 plants per hectare. [ Result ] With the increase of row spacing, the yield of cane leaves enhanced gradually. And the yield reached the maximum value of 12 656.3 kg/hm2 at 95 cm row spacing. Therefore, the yield of cane leaves could be enhanced by increasing the row spacing. At the same time, with the increase of row spacing, the yield of fresh tuberous roots enhanced gradually. And the yield reached the maximum value of 34 875.0 kg/hm2 at 90 cm row spacing, but then decreased at 95 cm row spacing. [ Conclusion] In general,90 cm row spacing could obtain reltiavely ideal yield of Guangshu 87.
