[Method] Under different seed treatment and seedling style, the seed germination rate and seedling emergence rate of A. nanchuanensis were investigated. [Result] tn both sand bed and direct sowing yellow soil, the seed germination rate, seedling survival rate and seedling emergence rate in the treatment II were all higher than those in the treatments I and III. The average seed germination rate, seedling survival rate and seedling emergence rate in sand beds were 1.5%, 16.27% and 13.95%, respectively higher than those in direct sowing yellow soil. The average seedling emergence rate in sand beds was 2.46% higher than that in containers. Among the 8 kinds of light matrix formulas, the growth of seedlings in the formula VIII was best. In the three treatment groups, the seedling emergence rates, seedling heights and ground diame- ters in the formula VIII were all significantly different from those in the other formu- las. The seedling growth in the formula I and III ranked second, while the seedling emergence rate, seedling height and ground diameter in the formula VII were the poorest. [Conclusion] If conditions allow, the formulas I （meadow soil：vermiculite：yel- low soi1=5：3：2）, III （meadow soil：perlite：yellow soi1=5：3：2） and VIII （peat：forest top soi1=6：4） should be promoted in seedling with light matrixes.展开更多
