摘　　要：利用3种不同的混合基质,对银柴Aporusa dioica、吊瓜木Kigelia africana、石笔木Tutcheria championi、红花油茶Camellia chekiangoleosa、大叶桂樱Laurocerasus zippeliana、铁冬青Ilex rotunda大容器苗抽梢和生长的影响进行了试验,结果表明:S2栽培基质(50%塘泥+30%煤灰+20%泥炭)有利于银柴、吊瓜木、铁冬青大容器苗的生长和抽梢,生产上可选用S2栽培基质;S3栽培基质(30%塘泥+40%椰康+30%蘑菇渣)的理化性质比较稳定,其有机质以及氮、磷和钾的含量也都较高,能更好地促进大叶桂樱的抽梢和生长,是较为理想的大容器栽培基质;石笔木、红花油茶这2个山茶科树种因其大容器苗不易成活,其最佳栽培基质还需进一步深入研究。By using 3 different cultivation medium,the container-seedlings of Aporusa dioica,Kigelia africana,Tutcheria championi,Camellia chekiangoleosa,Laurocerasus zippeliana,Ilex rotunda were carried out in order to research on the seedling’s sprout and growth.The results show that the substrate S2(50% pond mud +30% coir dust +20% sedge peat) was be propitious to the sprout and growth of A.dioica,K.africana and I.rotunda,can be used in the production of container matrix seedling;the substrate S3(30% pond mud +40% coir dust +30% spent mushroom compost) had steady physical and chemical characteristics and had higher organic matter contents of N,P and K,So it was an ideal substrate for the sprout and growth of L.zippeliana.With the substrate S2and S3,the containerseedlings of T.championi and C.chekiangoleosa were not easy to survive,so the ideal substrate requires to be study further.
