为了研究PAM和SAP对土壤水分及小麦生长的影响，在河套灌区以不施用PAM 和SAP为对照，研究PAM-1处理、PAM-2处理、SAP-1处理和SAP-2处理对土壤水分及小麦生长的影响。结果表明：①PAM 和SAP均能提高0～80 cm土层的土壤含水率，其中PAM-1处理的保水效果最显著；②PAM和SAP对不同土层土壤含水率的影响存在一定差异，其中在0～40 cm土层的影响最为显著，较对照土壤含水率平均提高21．41％，在40 cm土层以下土壤的含水率影响较小；③施用 PAM 能促进春小麦分蘖和根系的生长，进而可提高春小麦千粒质量及产量，其中PAM －1处理的效果最显著，增产达29．18％。

In order to study the effects of PAM and SAP on soil water and spring wheat growth ,taking the treatments without PAM and SAP as contrast ,four kinds of application methods ,namely PAM-1 ,PAM-2 ,SAP-1 and SAP-2 ,are tested in the Hetao Irrigation Dis‐trict .The results showed that :① PAM and SAP can both enhance the soil moisture of the 0~80 cm soil layer ,and the effect of PAM-1 treatment is the most obvious;② there is difference among the effects of PAM and SAP on soil moisture of different soil layers ,and the effect on 0~40 cm soil layer is the most significantly ,which is increased by 21 .41% than contrast treatment ,while the layer under 40 cm is less affected;③ the application of PAM can promote the growth of wheat tillering and root growth ,and then improve the spring wheat thou‐sand seed weight and yield ,and the effect of PAM-1 is the most significant ,the yield is enhanced by 29 .18% .
