Abstract

The purpose of this research is to investigate and compare the carbon sequestration capacity of aerial and underground organs of four species of salt marsh (Halocnemum strobilaceum), Ashnan (Seidlitzia rosmarinus), salt spike (Halostachys caspica) and Tamarix ramosissima and the plains herbaceous species (Artemisia sieberi). ) and comparing the amount of stored carbon It was done in saline and non-saline vegetation soil in Hoz Sultan pastures. Ten samples were taken from the aerial, underground and soil under the bushes and the amount of organic carbon in the samples as well as different soil characteristics were determined. The results of trait variance analysis showed that aerial organs of four resistant species and one control species are able to sequester carbon. The amount of carbon in the aerial parts of five species had a significant difference at the level of 5%. Gaz species had the highest amount of carbon in aerial organs. The amount of carbon sequestered in the soil under the gas bush was the highest with 52.5 tons per hectare, and the salt spike was the lowest with 29.9 tons per hectare. It seems that one of the reasons for this difference is the higher amount of wood textures and leaves produced by Goose compared to other species. Due to the high volume of aerial biomass and fodder production, as well as the shrub growth form, this species can be considered as a suitable species for pasture improvement projects and carbon storage in saline lands.
