调亏灌溉试验中土壤水分胁迫水平设置研究
Study on the Soil Moisture Stress Level in Regulated Deficit Irrigation Experiment
【摘要】 在讨论植物水分胁迫发展对植物生理过程的影响模式和土壤水分有效性范围划分的基础上,给出区分土壤水分胁迫水平的土壤水吸力值,然后结合试验测定的土壤水分特征曲线,换算出相应的土壤水分胁迫下的土壤含水量水平值。
【Abstract】 On the basis of discussing the influencing mode of plant moisture stress on plant physiological process and the division of soil moisture availability range,the water suction values partitioning soil moisture were put forward,and then the corresponding water moistures under water stress were obtained by conversing together with characteristic curve of water moisture.
