Taking oil sunflower, which is local main economic crop, as research object, energy state of different interfaces of Soil-Plant-Atmosphere Continuum in saline soil of north china was researched through field experiment. 以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。
The results indicated that root shrinkage has apparent difference for different four kind plants in experiment, i. e., maize> sunflower> acacia confusa> leucaena glauca, the root shrinkage state under water stress reflect the drought resistance of plant. 结果表明:植物根系收缩程度银合欢<台湾相思<向日葵<玉米,植物在水分胁迫下的根系收缩能反映植物的抗旱性;
