摘要

引进的11-07、16-08、Y1和SCZ 4个紫色甘薯[Ipomoea batatas (L.)Lam]品种分别在玉溪市3个不同海拔和3种不同的经果林地进行种植试验,分析其丰产性、品质等.结果表明,无论是从海拔差异还是从果树差异来看,SCZ的产量和品质较高,可作为有价值的商品紫色甘薯品种引进到玉溪经果林地推广种植;11-07可作为紫色甘薯高产的补充品种引进到玉溪经果林地种植；另外,经果林地种植紫色甘薯,以小树型为好.玉溪市经果林地可有选择地种植优良紫色甘薯品种.%In order to explore actual value of the woodland in mountainous region and semi-mountainous region of Yuxi city,four purple sweet potato cultivars,11-07,16-08,Y1 and SCZ were introduced to interplant in woodlands with different altitudes in Yuxi city,and its trait,yields,and quality were evaluated.The cultivar,SCZ,had higher yield and better quality not only in different altitudes but also with different fruit trees,it was a valuable purple sweet potato cultivar and could be planted for commercial production.11-07 could be used as a supplementary cultivar to interplant in Yuxi city.Besides,small tree was appropriate in interplant of purple sweet in woodlands.These results showed that interplant of purple sweet potato in woodlands of Yuxi city was feasible.
