Soil total salt

salt ions composition and correlations of different salt ions in habitat of Halogeton glomeratus in Minqin Oasis were studied. Results showed that H. glomeratus can accumulate salts and formed a certain salt island around its habitat. In the horizontal direction 0-60 cm away from H. glomeratus

the soil salinization degree aggravated with soil depth increases in 0-60 cm on the soil profile

among which anions were mainly Cl-

and SO42- and cations were Na+ and Ca2+. The main soil salinity were sodium chloride

calcium chloride

sodium sulfate and calcium sulfate

followed by magnesium chloride and magnesium sulfate. In 0-40 cm distance away from plant

the total salinity contents of the 0-20 cm soil layer on the soil profile were 0.98~1.52 g/kg and belonged to non-salinization soil

while that of the 20-40 cm and 40-60 cm soil layers were 2.25~2.30 g/kg and 3.10~3.16 g/kg

which belonged to light salinization soil and medium salinization soil

respectively. Furthermore

in the horizontal direction 60 cm distance away from the H. glomeratus

the total salinity content of 0-40 cm and 40-60 cm soil layers on the soil profile were 0.83~1.86 g/kg and 2.43 g/kg

which belonged to non-salinization and light salinization. There were extremely significantly positive correlations between soil salt content and ions contents except the content of HCO3-.
