摘　　要：选取12月基本停止生长的蘖芽为研究对象,采用粗沙、珍珠岩、腐殖土、椰糠4种基质,研究了不同基质条件下苏铁蘖芽的生根情况。研究表明,4种基质生根率均超过了80%,其中尤以粗沙和珍珠岩最好,达到了90%;在生根质量上,珍珠岩、腐殖土作为生根基质有利于须根的生长,腐殖土和粗沙则对根长和根粗生长较为有利;腐殖土和珍珠岩是苏铁冬季分蘖繁殖较为合适的生根基质。In this experiment,the author selects non-growing tiller buds as the target of the experiment and uses coarse silt,perlite, humus soil and coir four as the substrates to find out the difference of the rooting inducation in these four substrateconditions.The result showed that the rooting rate in these four types of substrate was above 80%,and the rooting rate in coarse silt and perlite was better than others（90%）. So perlite and humus soil are the proper substrates for rooting.
