Abstract: In this paper, the salt toterance of Kochia scoparia var. sieversiana is studied with field survey and laboratory tests. The results show: The salt solution concentration for the normal seed germination is below 8.1 atmosphere pressure ,Salinity for the normal emergence of seedlings is below 0.55% and for the normal growth and development is below 0.8% when the plant is cultivated in coastal salinized soil.The reason why this plant has stronger salt tolerance may be that it is able to absorb and accumulate a lot of mineral salts to regulate the cell osmotic potential, lowering water-potential of cells and avoiding dehydration them. Besides, this plant also has the characteristic of salt-dilution.
