摘要
以西部沙区平茬柠条沙柳粉和水泥为原料合成了营养成分全面、生产成本低廉的水溶性生物基磺酸钙盐,探究了保水固沙和土壤改良的效果.以柠条磺酸钙盐、沙柳磺酸钙盐和聚丙烯酰胺为材料,评价了抗风蚀性能,并在恒温培养箱、盆栽和户外3种典型环境中,评价其保水固沙性能,研究了对土壤理化性质的影响.结果表明:该生物基磺酸钙盐具有昼夜交替蒸发吸水的水平衡功能,较对照组具有良好的土壤和沙子保水能力,能显著提高土壤有机质含量,并能使微生物菌群数量增加1~20倍,在生态绿色、保水供肥、固沙结皮和提供全元营养等生态调理功能方面比聚丙烯酰胺等更具优势.施用生物基磺酸钙盐可以防沙固沙和恢复土壤生态,具有巨大的经济、社会和生态效益.
The effects of water-soluble bio-based sulfonates with comprehensive nutrients and low production cost were synthesized from Salix and Caragana powder and cement as raw materials in the western sandy area for water retention,sand fixation and soil improvement.Using calcium salt of Caragana sulfonate,calcium salt of Salix sulfonate and polyacrylamide as materials to evaluate its wind erosion resistance,its water retention and absorption performance and its effect on soil physicochemical properties were also evaluated under the three systems of constant temperature incubator,potted plant and outdoors.The results showed that the bio-based sulfonate presented the water balance function of alternating day and night evaporation and water absorption,and had better soil and sand water retention capacity than the control group,which can significantly improve soil organic matter and increase the number of microbial flora by 1 to 20 times;it had more advantages than polyacrylamide in terms of ecological conditioning functions such as greenness,water retention and fertilizer supply,sand fixation and crusting,and comprehensive nutrition.The application of bio-based sulfonates for sand control,sand fixation and soil ecological restoration had huge economic,social and ecological benefits.
