摘　　要：对厚荚相思组培苗和实生苗两种繁殖育苗方式造林林分的生长状况以及经济效益进行了对比试验,结果表明:组培苗造林的平均通直率比实生苗造林高31.4%;实生苗造林早期分枝较多的问题,在经过选优培育的基础上,利用组培苗造林,分枝较多问题得到了改善;从树高年生长量、材积的年平均生长量和经济效益来看,组培苗造林明显优于实生苗。A comparative study was corried out on the growth status and economic benefits between tissue cultured and seed seedlings. The results were as follows： the unbent rate of tissue cultured seedling was higher than seed seedlings. The problem of branching in early stage of ground of seed seedling was solved by planting tissue cultured seedlings through optimal selection. From the tree height growth, average growth of volume and economic benefits, forestation effect of tissue cultured seedlings was obvious super than seed growth of tissue cultured seedlings was not so obvious as tree height growth.
