摘要
综述了干旱逆境和覆盖地膜、施用植物生长调节剂、高剪苗等农艺措施对甘薯苗期根系形态生长和块根形成影响的相关研究。干旱抑制了苗期根系形态建成和块根形成,覆盖地膜、施用植物生长调节剂等农艺措施是提高苗期根系活力、促进块根形成、增加单株结薯数的有效措施;对甘薯苗期根系生长发育研究进行了展望。
The studies about effects of drought stress and agronomic measures such as mulching plastic film,applying plant growth regulator,and mowing at higher height on root growth and tuber formation were summarized. It showed that drought stress could suppress root morphogenesis and tuber formation at seedling stage. Mulching plastic film,applying plant growth regulator and so on were effective measures to enhance root vigor,promote tuber formation and increase tuber number per plant. And the researches on root growth and development of sweet potato at seedling stage were prospected.
