在美国,大多数商用甘薯是利用膨大了的贮藏根来繁殖秧苗。秧苗繁殖的特点随栽培品种而定。把生产有利用价值秧苗的数量提高到最大限度,同时把生产它们所需要的时间降到最低限度,可减轻育秧成本,便于提早移栽。尽管小贮藏根的产苗量常常少于大贮藏根的,然而通常却喜欢用小薯块排种,因后者比等量大薯块的产秧量多。催芽处理能增加早秧的产量。为了检查其薯块内部品质,可以把薯块切成薄片,而后将该薯块的近顶梢排种育苗。该方法可彻底评价其內部品质,但在很大程度上却削减了贮藏根的产苗潜力。在佐治亚州,很多栽
In the United States, most commercial sweet potatoes utilize expanded swamp roots to propagate seedlings. The characteristics of seedling propagation with cultivars and may be. Maximizing the number of productive seedlings while minimizing the time needed to produce them can reduce the cost of raising seedlings and facilitate early transplanting. Although small storage roots often produce fewer shoots than larger ones, they generally prefer to use smaller potato pieces because they yield more seedlings than larger pieces. Germination can increase the yield of early seedlings. In order to check the internal quality of the potato tuber, the potato tuber can be cut into thin slices, and then the top of the potato tuber can be planted for seedling. This method can thoroughly evaluate its internal quality, but to a large extent reduced the seedling potential of storage roots. In Georgia, many planted
