摘　　要：介绍缺钾对作物光合作用影响的主要方面,分别为影响植株的光合面积、影响光合作用中CO2的同化作用,影响叶绿体的结构及叶绿素的荧光特性、影响光合酶的活性。通过探讨影响作用及相关机理,为作物缺钾防治提供理论参考。This paper introduced the principle aspects of the influence of potassium deficiency on photosynthetic, such as the influence on plant photosynthetic area, the influence on CO_2 assimilation in photosynthetic, the influence on the structure of chloroplast and fluorescence characteristic of chlorophyll, and the influence on the activity of photosynthetic enzyme. By discussing the influences and related mechanism, it provided reference for crop prevention and control of potassium deficiency.
