In order to investigate the application effect of the halophyte on salty soil improvement,two kinds of halophyte,including Suaeda salsa and Salicornia,were selected and field experiments on the adaptability and salt absorption ability of them were carried out in both southern and northern of Xinjiang.The results showed that the survival rate of the two kinds of Halophytes in the southern Xinjiang was significantly higher than that in the northern Xinjiang,and the survival rate of Suaeda salsa was higher than Salicornia.The total salinity content of halophytes planted in the northern region was obviously higher than that of halophytes planted in the southern region,which was about 55% and 46% higher than for Suaeda salsa and Salicornia,respectively.It was concluded that Suaeda salsa and Salicornia were more suitable for growth in the southern region.Two types of halophytes salt absorption abilities in northern region were stronger than those of the southern region;the absorption ability of Salicornia was higher than Suaeda salsa.
