Abstract

Abstract: Due to its ability to improve sand stability and water retention, composite superabsorbent sand-fixation material was used in desertification control and restoration. The state of growth and physiological characteristics of cyanobacterial soil crusts, which were mixed with a sand-fixation material based on 4 mol·L^-1H₂SO₄ modified attapulgite with different mass ratio, were investigated. The results showed that the optimal ratio of cyanobacterial soil crusts to the sand-fixation material was 1∶3. The content of chlorophyll(a), soluble protein and soluble sugar were higher when the concentration of the mixed material was 500 g·m^-2 in comparison to 400 g·m^-2.

Key words: cyanobacterial soil crusts, attapulgite, sand-fixation material, physiological characteristics
