The individuals of Glehnia littoralis Fr.Schmidt ex Miq .introduced from the sandy beach of
Liandao Island at Lianyungang in Jiangsu Province were planted in 6 kinds of soil medium at Nanjing , such as

(Ⅳ), humus (Ⅴ)and 1 3 sand + 1 3 humus + 1 3 yellow-brown earth (Ⅵ ). The survival rate , growth
situation , blooming and fruiting of G. littoralis planted in the above-mentioned 6 kinds of soil medium were
observed and compared . The results indicated that the survival rate of these individuals was the highest in Ⅵ ,
the nutrition growth in Ⅱ was the best , in Ⅲ the fruiting rate and the seed quantity were the highest , and the
growth and development in Ⅳ was the most unfavorable .According to 10 indexes of the growth and
development , the advantage of the above-mentioned different soil media were evaluated and ordered for planting
this species , and the order is Ⅲ >Ⅱ >Ⅰ >Ⅵ >Ⅴ >Ⅳ
