| 摘 要： | 以不同剂型、不同浓度对土壤施入聚丙烯酸胺，探讨其对土壤物理性质的影响，试验结果表明:土壤经聚丙烯酸胺处理后一般沉降系数增大9%，分散系数减少7%～及9%，结构系数增大3%～8%，水稳性团粒含量增加30%～50%，结构性能增强3%～8%，土壤渗透性能增大32%。这些指标证明该材料是较好的土壤结构改良剂之一，对防治土壤侵蚀起重要作用。

| Abstract: | The effect on soil physical nature was probed by application of different dose and various polyacrylamide consistencies. The results should that the general sediment coefficient is increased more 9%, the structure coefficient more 3%~8%, the content of hydric stable dumpling more 30%~50%, the structure function more 3%~8%, the soil permeability more 32% and the disperse coefficient is less 7%~19% after by polyacrylamide treatments. These index have proved that polyacrylamide material be good improvemental matter to soil erosion control. |
