Abstract:: The purpose of this paper is to study the effect of seed-base afforestation in saline-alkali land. Preparation of platform field, water-salt dynamic, the survival rate of different seed-base and tree species were investigated in coastal argillaceous saline-alkali land of Tang Shan. Results showed that, there was a close relation between the water content and salt content, in soil surface layer, the trend of soil salt and water was similar while the trend was reverse in middle and deep layers. The average salt of soil decreased year by year by preparation of platform field. The afforestation of seed-base has achieved initial success in saline-alkali land which the three-year survival rate of seed-base reached 30% in Rhus typhina, Locust, Amorpha fruticosa L. The survival rate of seed-base which the volume ratio of new soil, peat, vermiculite and perlite was 50∶30∶10∶10 was better than other seed-base. This seed-base which could improve the properties of plant growth environment was more suitable for tree species.
