摘　　要：以当地主要经济作物油料向日葵为研究对象,采用田间试验对北方盐渍化地区土壤-植物-大气连续体中不同界面的能态进行了研究。通过相关性分析得出土壤基质势,叶水势,大气水势三者在时间和空间上都有很大的差别。该研究为盐渍化地区农业生产和节水灌溉提供了理论基础。This research mainly deals with energy state of different interfaces of soil-plant-atmosphere continuum in saline soil of north china. The research object is the oil sunflower that is the main economic crop. Soil matric potential, leaf water potential and atmosphere water potential is diversity in temporal and spatial variation. It offers the croeoretical basis and technical support for agriculture productivity and water-saving irrigation, and enriches and consummates the theory of water-saving irrigation in saline soil.
