摘　　要：分析了温室黄瓜的茎流与温室内各环境因子之间的关系,研究了不同供水情况下黄瓜的茎流变化规律。试验表明,实施滴灌时,黄瓜的茎流变化与作物的蒸腾速率表现出一定的相关性,结合茎流与蒸腾速度2方面的指标,将更有利于指导温室作物的节水灌溉。Relations between stem sap flow of cucumber and environmental factors were analyzed in greenhouse; simultaneously varieties of sap flow under different water supply condition was researched. It is proved that the certain correlation lies in sap flow and transpiration rate of cucumber under drip irrigation according to results of experiments. Effectively combined sap flow and transpiration rate is help the guide for water-saving irrigation in greenhouse.
