| 摘 要： | 综述了水分胁迫条件下,施用磷肥对小麦抗旱性影响的研究进展情况,并且分析了施用磷肥提高小麦水分利用效率的机理.在水分胁迫条件下,磷作为一种营养物质,能显著促进小麦的根系发育,改善植株的水分状况,增加束缚水的含量,提高膜的稳定性和耐脱水能力及渗透调节能力,维持小麦生长过程的正常进行,提高小麦的水分利用效率.从而增强了小麦对干旱缺水环境的适应能力,提高了小麦的抗旱性.

| Abstract: | Research progress in the effect of phosphorus nutrition on wheat drought resistance under water stress was reviewed.The mechanism of phosphorus fertilizer in increasing wheat water use efficiency was analyzed.Phosphorus as a kind of nutrition could stimulate root growth,improve water condition,increase bound water content,enhance membrane stability and desiccation tolerance as well as osmotic adjustment ability,maintain wheat growth,increase water use efficiency and enhance wheat drought resistance. |
