摘　　要：作物缺水量是作物生长需求的重要指标之一,依据作物生理需水量建立作物缺水模型是作物缺水量研究的新方法。作物叶面积和茎秆直径是作物生长生理指标的重要因子之一。本研究通过试验建立作物不同缺水量对作物叶面积和茎秆直径变化的影响,并依此为依据建立作物缺水生理指标变化模型,经过检验可以得出模型效果较好。作物缺水模型可以根据不同生理指标变化模型判断出不同作物缺水量时作物所表现出来的生理指标变化,为进一步研究依据不同生理指标变化指导作物定量补水研究奠定基础。Crop water shortage are one of the important indicators of demand for crop growth,established crop physiological model according to the crop water requirement is a new method of crop water shortage.Leaf area and stem diameter are one important factor in crop physiological indices.This study was to establish the impact of different crop water shortage on leaf area and stem diameter changes by testing,and according to this,the model of crop water shortage physiological index was established,the test showed that the model is better.Crop water shortage model can be based on different physiological indicators to determine the changes in crop water shortage in different crops showed the changes in physiological indicators.In order to lay the foundation for further study of quantitative crop water based on different physiological indicators.
