摘　　要：研究了4种不同的保水剂施用方法对马铃薯"合作88"生理指标及农艺性状的影响。结果表明:保水剂的效果具有时效性,不同的施用方式发挥作用的时间不同;保水剂蘸种处理有利于提高出苗率,保证出齐苗;所有保水剂施用方式均能提高土壤含水量,其中穴施保水剂效果最好;保水剂沟施以及保水剂苗期穴施在抗旱性生理指标上表现较好;利用模糊隶属函数来综合评定不同保水剂施用的效果,得出除保水剂蘸种处理与自然对照无差异外,其余所有保水剂施用方式的抗旱效果均优于自然对照,其中保水剂苗期穴施的抗旱保水效果最好,评价指数比自然对照高出71.43%;苗期穴施保水剂对提高马铃薯的单产有很好的效果,尤其是提高了大薯的产量和品质。The effect of different application methods of super absorbent polymer （3At＇） on potato varieties of ＂cooperation 88＂ was studied. Several agronomic characters and physiological indicators were used in this field experiment. The results show that the effect of SAP had time bound, different SAP application methods acted in different periods. Seed dressing with SAP was helpful to improve the e- mergence rate. All SAP application methods improved soil moisture content, and hole-used method with SAP at seeding stage had highest soil moisture content. Furrow application with SAP at seeding stage and hole-used method with SAP at seedling stage had better effects on physiological indicators. As a comprehensive assessment, ＂fuzzy subordination method＂ results showed that all SAP application methods were better than natural control except seed dressing with SAP method, and hole-used method with SAP at seedling stage was the best SAP application method in this experiment, the assessment index was 71.43% higher than natural control. Hole-used method with SAP at seedling stage improved potato yield, especially improved the yield and quality of large tubers.
