Abstract:: Soil algal crusts are mainly formed by the cementation of soil algae and soil particles, and have excellent ecological functions such as soil and water conservation, soil improvement, windbreak and sand fixation. In order to study the improvement effect of soil algal crusts on saline-alkali soil, the experiment was carried out in the saline-alkali land of Hetao Plain. We inoculated C. miniata HJ-01, C. miniata HJ-01 and S. javanicum, C. miniata HJ-01 and indigenous filamentous mixed algae in the field experimental area, and the soil algal crusts were artificially cultured. The results showed that after 45 days of artificial algal crusts development, within the depth of 0—10 cm, the water loss decreased slightly, soil pH value decreased slightly, soil electrical conductivity decreased 57%(p<0.05), and available N and available P increased(p<0.05); the activities of urease, sucrase, catalase and alkaline phosphatase in 0—5 cm soil layer increased by 52.1%, 20.7%, 16.7% and 41.7%, respectively(p<0.05). Therefore, the artificial soil algal crusts could improve the saline-alkali soil effectively.
