中文摘要:
      为在浙江省更好地种植和应用甘薯品种浙紫薯3号,对其早收栽培的物候期、形态特征、生长动态,以及主要经济性状进行了观察试验。结果表明:浙紫薯3号于5月底扦插,其还苗期、分枝期和封垄期与其他类似品种没有明显差异;浙紫薯3号薯蔓较长且较细,一般基部分枝7~8个;单株结薯数较多,结薯较早,前期薯块膨大较快,薯皮、薯肉均紫色,小薯的粗纤维也较少,口感较软,食味较好,比较适宜于作为迷你甘薯种植。
英文摘要:
      Abstract: In order to better cultivate and apply sweet potato 'Zhezishu No.3', the phonological period, morphological characteristics, growth dynamics and main economic characters of early-harvesting cultivation were observed. The results showed that there was no significant difference between 'Zhezishu No.3' and other similar cultivars in seedling-returning, branching and ridge-closing stages when the cutting time was at the end of May. The vines of 'Zhezishu No.3' were longer and thinner, and 'Zhezishu No.3' had 7~8 branches at the base of the plant. The number of tubers per plant was higher. It formed the tubers earlier and the tubers swelled faster in early stage. The skin and flesh of tubers were purple, and the crude fibers of small tubers were purple. It had less coarse fibre, soft and good taste and was suitable for mini sweet potato cultivation.
