Cations of sodium, potassium, magnesium and calcium play important roles in adaptation of plant species to arid conditions. The research in 93 years to evaluate the uptake of cations of sodium, potassium, magnesium and calcium cations such Halocnemum Strobilaceum in Meyghan and compared to the depth ( 0 to 30 cm ) soil samples were analyzed and plant feet in three season ( winter, spring, summer ) was performed . For this purpose, 10 samples from the aboveground plant parts Ha. Strobilaceum and the soil under the plant in three seasons to just completely random sampling was conducted. By transferring the samples to the lab, cations of sodium, potassium, magnesium and calcium were measured. Finally, using one-way ANOVA was used to examine the significant difference values between samples. The results showed that the highest amount of 4 cations starting in the spring than in winter and summer growing season plants there and vice versa least the same amount of cations in the soil in the spring event, which shows high absorption and herbal Ha. Strobilaceum at the start of the growing season, as well as the cations accumulation of soil in direct connection with the distribution of the species Ha. Strobilaceum there.
