近年来,为了探索甘薯块根以外部分的留种繁殖,我們同时进行了甘薯藤蔓留种繁殖和柴根(又名牛蒡权)留种繁殖的試验。試驗結果,藤蔓留种,貯藏困难,因为藤蔓稍干,容易失去生活能力,湿了又易腐烂;同时藤蔓养分少,直接扦插,成活率低,即使成活,生长也很緩慢。此外,藤蔓留种, In recent years, in order to explore part of the sweet potato tuberous part of the remaining breeding, we also conducted sweet potato vines breeding and Chai Gen (aka burdock right) to stay breeding. As a result, the vines remained inoculated and stored for a long time. Because the vines were a little dry, they easily lost their ability to survive and become wet and perishable. At the same time, the vines had fewer nutrients and cuttings directly. Their survival rate was low and they grew very slowly. In addition, the vine to stay seed,
