英文摘要	通过连续测定灌溉淹水和落干过程中的稻田土壤 Eh,研究黄河上游宁夏引黄灌区水稻生育期内表层土壤的变化规律,结果表明,表层土壤与农田灌水与落干过程紧密相关,灌水后淹水过程中,表层土壤Eh下降;淹水后落干过程中表层土壤上升。灌溉淹水和落干过程中,土壤电导率与土壤极显著负相关(p<0. 05),而灌溉水量、施肥量及地表温度对表层土壤Eh的影响均不显著(p<0. 05)。; Soil Eh in the paddy field was continuously measured to study the response of Eh in the soil surface layer in paddy rice to frequent flooding and drying cycles in Yellow River irrigation area of Ningxia Autonomous Region. The results showed that soil Eh in the surface layer was closely related to the process of drying and rewetting. Soil Eh in the surface layer decreased during the flooding process,while soil Eh increased during the drying stage. There was a significant negative correlation between soil Eh and soil pH (p<0. 05) while there were no significant relationships among the irrigation amount, fertilization application rate,temperature of the surface soil and soil Eh (p<0. 05).
