| 摘 要： | 本试验对金沙江流域现有的5个甘薯地方良种种薯的萌芽习性进行了比较研究,结果表明,这些品种种薯萌芽能力均低于对照品种徐薯18,从播种到出苗的平均气温变动在17.6～18.6℃之间,有效积温变化在137.0～291.5度·日范围.因而,在推广这些甘薯地方良种时,应适当提早育苗播种时间,以保证大田甘薯的适时早插,夺取甘薯高产与稳产.

| Abstract: | The sprout habits of seed tuber of five local sweet potato varieties in Jinsa River zone were studied. Rseults showed the ability of seed tuber sprout of these local sweet potato varieties were marked lower than Xushu 18. The average temperatures from sowing to seedling in these local varieties were 17.6-18.6C. The available temperature summation of seedling in these local varieties were 137-291.5c d. It suggests that these local varieties above would shift to an earlier sowing date, so as to cultivate health seedling. |
