[目的]为甘薯立柱式无土育苗模式的推广提供科学依据。[方法]采用立柱式育苗和土床育苗方法,对比两种育苗方式下薯苗的相关生长性状。[结果]与土床育苗相比,金玉和苏薯8号两个品种在立柱式育苗下,其百苗重、同长度百苗重、叶片数、叶片横纵长度、苗长和茎粗方面均显著提高,特别是在前3次剪苗期,提高幅度更为显著。[结论]立柱式无土育苗在甘薯育苗中有较大的优势,值得推广应用。
[Objective] The research aimed to provide a scientific basis for the popularization of sweet potato column soilless seedling breeding model. [Method] The column growth and soil bed seedling raising methods were used to compare the growth characteristics of potato seedlings under two kinds of seedling raising methods. [Result] Compared with soil bed nursery, Jinyu and Shushu 8 under the columnar nursery, its seedling weight, the same length of 100 seedling weight, the number of leaves, vertical and horizontal length of leaves, seedling length and stem diameter Significantly increased, especially in the first three cutting seedlings, the increase is more significant. [Conclusion] The column-type soilless seedlings had greater advantages in sweet potato seedling breeding and should be popularized and applied.
