Abstract The effects of addition on hydrologic characteristics of Seed-base materials and the effects of afforestation technique of Seed-base on growth of plant are studied. The results showed that with the active conditioner dosage of soil increasing, the water permeability and hygroscopicity rate of Seed-base are increased, the surface evaporation of which is reduced, and the growth of ground upside of plant is accelerated. The addition of dosage of preventing soil from erosion has no apparent effects on water permeability of Seed-base materials and the growth of plant, however, it is helpful to maintain the form of Seed-base, and improve the effect of construction. With direct seeding by Seed-base, the thick of roots can be increased, the root of plant can be accelerated growing down into deeper soil, and the ability of resisting drought of seedling can be enhanced.
