Abstract: Hetao irrigation zone in Inner Mongolia possesses enormous potential for improving fast-growing and high-yield plantation,thereby introducing Salix (‘Zhuliu’) is a new trend for forestry industry development in Hetao irrigation zone.An experiment for investigating drought resistance,salt resistance,and alkali resistance of Salix (‘Zhuliu’) introduction was conducted in Hetao irrigation zone.The results suggested that 1) Salinity-alkalinity is primary factor limiting Salix (‘Zhuliu’) planting.Salt tolerance threshold for green Salix (‘Zhuliu’) and red Salix (‘Zhuliu’) is 1.92% and 0.53%,respectively.Alkali resistance threshold for red Salix (‘Zhuliu’) is pH 9.34.2) The drought resistance of green Salix is higher than that of red Salix.3) Green Salix (‘Zhuliu’) should be planted in heavy saline-alkali zone,and red Salix (‘Zhuliu’) planted in lighter saline-alkali zone.These results indicated that green Salix(‘Zhuliu’) is the first choice,when Salix (‘Zhuliu’) planted in Hetao irrigation zone.

Key words: Salix(‘Zhuliu’), drought resistance, salinity-alkalinity, Hetao irrigation zone
