水分胁迫对大豆生长与产量的影响及应对措施

在大豆生长发育过程中,非生物胁迫严重影响理化进程并降低产量,其中水分胁迫是所有其他非生物胁迫（高温、低温、土地瘠薄、盐碱等）损失的总和。为了提高大豆在水分胁迫中的抗逆性,通过归纳水分胁迫对大豆生长发育及产量的研究现状,总结干旱和淹水胁迫对大豆形态结构、生理指标及产量指标的影响,分析抵御水分胁迫的应对措施和有效方法。指出目前抗旱防涝存在的问题,并提出解决方案,以期降低水分胁迫对大豆生产造成的损失。

Water Stress: Effects on Growth and Yield of Soybean and the Countermeasures

During the growth and development of soybean, abiotic stress seriously affects the physiological and biochemical process of soybean, and reduces the crop yield. Water stress equals to the total loss of all other abiotic stresses, such as high temperature, low temperature, barren land, saline-alkali, etc. In order to improve the soybean resistance to water stress, it is necessary to summarize the research progress on the water stress affecting soybean growth and yield, and the possible impacts on morphological structure, physiological parameters and yield components, and analyze the countermeasures and effective solutions. The paper points out crucial problems in drought and waterlogging disasters, and provides feasible suggestions for reducing the yield loss caused by water stress.
