聚丙烯酰胺是一种线型的水溶性聚合物，因其具有很强的絮凝性，是较好的土壤结构改良剂之一，试验证明：以适当的浓度和剂型施入土壤，能大大地提高上壤的抗蚀力和抗冲力，防治田间水土流失的效果可达60％～70％。
Polyacrylamide is a linear water-soluble polymer, because of its strong flocculation, is one of the better soil structure improver, the test proved that: the appropriate concentration and dosage form applied to the soil, can greatly Improve soil erosion resistance and impact resistance, prevention and treatment of soil erosion effect of up to 60% to 70%.
