Abstract

This study deal with investigation of the effect factors on dryness of planted Haloxylon considering the importance of its role in soil stabilization especially mobile sands and also enormous costs were done for biological developments. For this research one peer site from planted Haloxylon area, 5 vigor Haloxylon sets, 5 semi-vigor Haloxylon set and 5 wilted Haloxylon sets were chosen based on plants appearance in the study site. Haloxylon shrubs were cut from the ground and the leaves were separated, then ratio of leaf to stem, therefore this ratio become an indicator of given vegetation. From 15 total selected Haloxylon sets, 15 samples of shots and 15 samples of roots were taken for conducting chemical tests and value of sodium, calcium, magnesium, potassium, and phosphorus were determined in the laboratory based on the standard methods. The effects of measured factors on plant vitality index were evaluated by univariate analysis of variance. The results suggest that with regards to the important role of phosphorus, potassium, calcium and magnesium in plants, their shortage in shoots reduce vigor index.
