Strengthening soil and water conservation and soil fertility are important tasks of the current land improvement. Summing up theprevious soil conditioner polyacrylamide(PAM)research results,this paper summarized the regulation effect and that mechanism of soilconditioner PAM,the application prospect of PAM,in order to provide references for further research and extension the use of PAM. PAMcan cement soil particles,improve soil physical properties,prevent the losses of soil,water and fertilizer,increase crop yields,improve thesaline and prevent wind erosion without toxic effects on the environment. The regulation effect of PAM on soil depends on its molecularweight,hydrolysis the degree and the dose and so on,which hinders its promotion of use in the actual production. Application technicaltheoretical system of PAM should be established and the new PAM research should be accelerated to improve the regulation effect andeconomic benefits of PAM,and for PAM used to provide theoretical support in the actual production.
