摘　　要：以不同用量梯度生物基磺酸盐喷施沙土表面,测定固结层厚度、硬度以及地表温度、表层土壤水分,研究其固沙性能及对植物种子发芽和出苗的影响。结果表明:固结层厚度和硬度均随生物基磺酸盐用量的增加而增加,生物基磺酸盐可显著提升沙土表层温度,沙土保水性能在用量50~100 g·m^(-2)时较好,在不同生物基磺酸盐用量情况下,固结层厚度为5.56~15.13 mm,硬度为0.24~1.69 kg·cm^(-2),存在极显著差异;生物基磺酸盐对种子发芽和出苗有抑制作用,当用量大于100 g·m^(-2)时出苗率显著下降,生物基磺酸盐在风沙土治理中的适宜用量为50~100 g·m^(-2),通过合适的稀释倍数可减轻其对种子萌发的抑制作用。By designing different dosage of bio based sulfonate, the consolidation layer, surface temperature and surface soil moisture after spraying were measured, and their effects on plant seed germination and emergence were observed. The thickness and hardness of the consolidation layer increased with the increasing of the amount of bio based sulfonate. The thickness of the consolidation layer was 5.56-15.13 mm, with an average thickness of 10.42 mm. The hardness of the consolidation layer was 0.24-1.69 kg·cm^(-2), with an average hardness of 0.79 kg·cm^(-2);The use of bio based sulfonate significantly increased the surface temperature of sandy soil;The soil water holding capacity was better when the dosage was 50-100 g·m^(-2). Sulfonate had a certain inhibitory effect on seed germination and emergence, and the emergence rate decreased significantly when the dosage was greater than 100 g·m^(-2).The suitable dosage of bio based sulfonate in aeolian sandy soil treatment should be 50-100 g·m^(-2), and its inhibition on seed germination can be reduced by increasing the dilution ratio.
