摘    要:为研究不同茎蔓节段的栽培效果,以4个甘薯品种1 m长的茎蔓为材料,按30 cm平均分为一(尖)、二(中)、三(近基部)3个苗段,分别测定其种植效果。结果表明,一段苗、二段苗的分枝数高于三段苗,产量也显著高于三段苗。所以,在甘薯生产上应尽量选用近顶端的一段苗、二段苗来进行栽培;提倡分段栽插,第三段苗不宜与第一、二段苗混合栽插,以便采用不同的栽培措施,提高甘薯的产量。通过试验为南方地区采用老茎或宿根育苗的甘薯生产提供科学依据。

The Growth and Yield of Different Sections of Vines Cuttings of Sweet Potato
Institution:Li Mingfu, Xu Ningsheng, Xu Jianhui, Li Yuping, Lu Xingxing, Dong Shaohui (1.Yuxi Agricultural Vocation-technical College, Yuxi Yunnan 653100; 2.Industrial Crop Research Institute, Yunnan Academy of Agricultural Sciences, Kunming 650200; 3Yunnan Potato Engineering and Technology Research Center, Kunming 650200)
Abstract:To decide the effect of different vines cuttings, the growth and yield of the different vine cuttings with30 cm long of sweet potato were evaluated. The result showed that both the number of branches and the yield offirst section(top section) and the second section(middle section) were significantly higher than the thirdsection(base section). So, the first and second sections should be chosen for sweet potato cuttage rather thanthe base sections. It was recommended that the first section(top section) and the second section(middlesection) should not be mixed with the third section(base section) when planting sweet potato vine cuttings. Thisresult could provide useful information for sweet potato production.
