Through analysis of water-soluble salt contents in 13 dominant plant species in the area of Hutubi Cattle Farm, Xinjiang, the characteristics of their distributions and accumulations are expounded:1) on the level of water-soluble salt contents in most plant species, Na+>K>Mg2+>Ca2+, Cl-, Na+ was more than 20, 000 μg· g-1, Ca2+was less than 800 μg· g-1, Cl- reached 4. 16%, was only 0. 11 %, the range of total salt contents was 7. 19 % ￣45. 1 % 1 2) In different plant species, the coefficient of variations of...
