【摘要】 简易风洞试验和自然风蚀试验表明,施用聚丙烯酰胺可以改善土壤抗风蚀能力,减少土壤风蚀量。聚丙烯酰胺用量增加,土壤风蚀量减少。施用聚丙烯酰胺1～10g/m2,土壤风蚀量仅为对照的1%～47%。更多还原

【Abstract】 Simple wind tunnel test and natural wind erosion experiment indicate that polyacrylamide can improve the ability of soil against wind erosion and reduce its volume. The volume of soil wind erosion diminishes with the raising of volume of polyacrylamide. In general, the soil wind erosion volume is only 1%～47% of the normal if using polyacrylamide 1～10g per square meter.更多还原
