水盐胁迫条件下作物根系吸水模型研究进展及展望

The Research Progress and Prospect of the Root Water Uptake Models under Water and Salt Stress

提高盐渍化土壤农业生产力已成为边际土壤地力提升的重要组成部分及途径,研究盐分胁迫对根系吸水的影响及其根系吸水模型的建立是该方面的重要研究内容之一。介绍了作物根系吸水模型的研究进展,在此基础上,对目前国内外常用的水盐胁迫条件下作物根系吸水模型及其相关研究作了综述指出由静态向动态方向发展、突出水分胁迫与盐分胁迫对根系吸水耦合、体现作物根系吸水特征空间差异是水盐胁迫条件下作物根系吸水模型研究的重点。

Improving the agricultural productivity of soil salinization has become an important part and a way to promote the marginal soil fertility, and studying the influence to root water uptake and the models about the root water uptake is important. This paper first introduces the research progress of the root water uptake models. Then based on this, the commonly used crop root water uptake model and its related research under the water salt stress conditions at home and abroad are reviewed, which points out the development from static to dynamic, outstand water stress and salt stress＇s impact on the root water uptake coupling and reflects crop root water uptake characters space difference is the key to crop root water uptake model under the salt water stress.
