研究安徽紫色甘薯(Ipomoea batatas Poir)在黔中地区的引种适应性和丰产性，并筛选出适宜的栽插密度，为紫色甘薯在黔中及生态类似地区大面积生产种植提供科学依据。结果表明：紫色甘薯植株性状、结薯数变化趋势与产量呈一致性，产量随栽插密度增加呈现出先升后降的趋势，最佳栽插密度为4896株/667 m2获得最高产量(P＜0.01)。
研究安徽紫色甘藷(Ipomoea batatas Poir)在黔中地區的引種適應性和豐產性，併篩選齣適宜的栽插密度，為紫色甘藷在黔中及生態類似地區大麵積生產種植提供科學依據。結果錶明：紫色甘藷植株性狀、結藷數變化趨勢與產量呈一緻性，產量隨栽插密度增加呈現齣先升後降的趨勢，最佳栽插密度為4896株/667 m2穫得最高產量(P＜0.01)。

The adaptability, yield and appropriate density of Anhui purple sweet potato (Ipomoea batatas Poir) in central Guizhou were researched in order to provide scientific basis for the planting of purple sweet potato in Guizhou and similar ecological area. The results showed that plant traits, tuber number and yield of purple sweet potato had the similar changing trend. Yield presented the trend of first increasing and then decreasing. The best planting density was 4 896 plants/667 m2 and obtained the highest yield (P<0.01).
