摘  要:
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0~80cm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0~40cm土层的影响最为显著,较对照土壤含水率平均提高21.41%,在40cm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%。

摘  要:
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-1and SAP-2,are tested in the Hetao Irrigation District.The results showed that:1 PAM and SAP can both enhance the soil moisture of the 0~80cm soil layer,and the effect of PAM-1treatment is the most obvious;2there is difference among the effects of PAM and SAP on soil moisture of different soil layers,and the effect on 0~40cm soil layer is the most significantly,which is increased by 21.41%than contrast treatment,while the layer under 40 cm is less affected;3the application of PAM can promote the growth of wheat tillering and root growth,and then improve the spring wheat thousand seed weight and yield,and the effect of PAM-1is the most significant,the yield is enhanced by 29.18%.
