摘要: 为筛选适宜武陵山区种植的紫薯[Ipomoea batatas (L.) Lam)]品种,采用随机区组试验设计,以鄂紫薯1号为对照,对引进的省紫薯、南紫薯008、绵紫薯9号、南紫薯014、南紫薯015 5个品种,从农艺性状、鲜薯产量及硒含量等方面进行比较分析。结果表明,在武陵山区气候条件下,绵紫9号、省紫薯、南紫薯015 3个品种大中薯率为87.27%~96.15%,鲜薯产量为39 151.20~51 586.80 kg/hm2,与对照差异明显,且硒含量为0.29~0.54 mg/kg,均达富硒标准,初步认定其适宜引入本区域种植。

Abstract: In order to select the purple sweet potato[Ipomoea batatas (L.) Lam)] varieties suitable for planting in Wuling mountain area,a randomized block test design was adopted,and Ezishu No.1 was used as the control. Five introduced varieties,such as Shengzishu,Nanzishu 008, Mianzishu No.9,Nanzishu 014 and Nanzishu 015,were compared and analyzed in terms of agronomic characteristics, fresh potato yield and selenium content. The results showed that under the climate conditions of Wuling mountain area,the rate of large and medium-sized potatoes was 87.27%~96.15%,the yield of fresh potatoes was 39 151.20~51 586.80 kg/hm2,which was significantly different from the control,and the content of selenium was 0.29~0.54 mg/kg, all of which reached the standard of rich selenium. It was preliminarily determined that it was suitable for planting in this area.

Key words: purple sweet potato[Ipomoea batatas (L.) Lam)], introduction, suitability
