摘要/Abstract

摘要： 由于具有提高沙土的稳定性和保水性等特征，复合高吸水性固沙材料在荒漠化土地治理方面具有一定的潜力和应用前景。研究了蓝藻结皮在不同比例凹凸棒基高分子固沙材料中的生长状态和生理特性。结果表明:蓝藻结皮与经4 mol·L^-1硫酸改性后的凹凸棒基高分子固沙材料以1∶3质量比配比生长情况最佳；比较了复配材料喷洒量为400、500g·m^-2处理下蓝藻叶绿素a、丙二醛、可溶性蛋白及可溶性糖含量等生理指标，喷洒量为500 g·5m^-2的蓝藻结皮与经4 mol·L^-1硫酸改性后的凹凸棒基高分子固沙材料生理特性较好。

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
