为给蔬菜节水灌溉技术大面积生产示范提供技术依据，研究了覆盖地膜、土壤保水剂、蒸腾抑制剂3种不同的减蒸技术组合对温室秋茬黄瓜品质、土壤贮水量变化及水分利用效率的影响。试验结果表明，覆盖地膜+土壤保水剂减蒸技术有利于提高黄瓜品质；覆盖地膜+蒸腾抑制剂、覆盖地膜+土壤保水剂+蒸腾抑制剂等综合减蒸技术能够增强土壤持续供水能力；在相同的灌溉制度下，采用减蒸技术有利于提高秋茬设施黄瓜土壤水分利用效率。

In order to provide technical base for extensive production and demonstration of water-saving vegetable irrigation technique, we studied effeccts of different combinations of reducing evaporation technique such as plastic film mulching, soil water-holding agent, transpiration retardant on the quality, soil water storage change and water use efficiency of autumn cucumbers in greenhouse. The results showed that, the combination of plastic film mulching and soil water-holding agent contributed to improve quality index of cucumber. Comprehensive reducing evaporation techniques, such as plastic film mulching+transpiration retardant, film mulching+soil water-holding agent+transpiration retardant were able to strengthen the soil's ability to constantly supply water. Under the same irrigation program, reducing evaporation technique helped to improve water use efficiency of the soil that cultivates autumn cucumbers.
