摘　　要：为筛选山豆根组培苗适宜的移栽基质,研究了疏松黄土、腐殖土、珍珠岩、蛭石和松树皮5种基质对山豆根组培苗的成活率及幼苗素质(苗高、地径、叶片数)的影响。结果表明:移栽于腐殖土基质的山豆根组培苗成活率和幼苗素质显著优于其他基质,具体表现为山豆根组培苗成活率为100%,移栽3个月后腐殖土基质的山豆根组培苗平均苗高5.8cm,基部茎粗1.43mm,叶数5.53片。结论:腐殖土基质是山豆根组培苗的适宜移栽基质。To screen the appropriate transplant matrix for the tissue culture seedling of S.tonkinensis,the influence of loosen loess,humus soil,perlite,vermiculite and pine bark on the survival rate and quality（seedling height,ground diameter and leaf number）was studied.Results：The survival rate and quality on the matrix of humus soil were superior to other matrix,the seedling survival rate reached 100%.Three months after transplanting,the mean seedling height,ground stem diameter and leaf number were respectively 5.8cm,1.43 cm and 5.53.Conclusion：It＇s an appropriate transplant matrix for the tissue culture seedling of S.tonkinensis.
