水溶性固沙剂对沙地土壤蒸发的影响
Effects of Water-soluble Sand Fixing Agent on Soil Evaporation in Sandy Land
摘要
Abstract
In order to explore the effect of different water-soluble sand fixing agents on soil water evaporation,4 water-soluble sand fixing agents including artemisinin gum,flaxseed gum,locust bean gum and bio-based sulfonate were selected,and 5 dosages of 10,20,30,40,50 g·m-2 were designed for each agent,with no sand fixing agent added as control(CK).Through the indoor simulation evaporation test,the evaporation intensities of different types and different additions of sand fixing agents were measured,and the differences between them were analyzed.The results showed that the water retention effects of 4 sand fixing agents were locust bean gum,flaxseed gum,artemisia glue,bio-based sulfonate,and locust bean gum were significantly better than bio-based sulfonate.The water retention performance of 4 sand fixing agents at 40 and 50 g·m-2 were significantly higher than that of CK(P<0.05).4 sand fixing agents had strong water retention effects on the deep soil of 5-10 cm.In summary,water-soluble sand fixing agents had a good water retention effect,and locust bean gum had the best performance.Above results could provide a theoretical basis for the application of water-soluble sand fixing agents.关键词
