钾可促进光合作用,有利于蛋白质合成,促进植物经济用水,加速同化物向贮藏器官流动,增强抗逆性和抗病力。提高产量。近年来的研究结果表明,钾在植物生理中有多方面的作用。一、钾是多种酶的活化剂钾和氮磷元素相比较,钾在细胞及整个植物中是十分活跃的,很容易用水从植物组织中提取出来。由于钾与有机分子结合松散,且有较高的活动性,所以钾可以参与许多代谢反应。由钾活化的酶有三类:合成酶、氧化还原酶、转移酶。钾在合成过程中及各种能量代谢反应中是不可缺少的。这些酶反应特别需要钾, Potassium can promote photosynthesis, is conducive to protein synthesis, promote plant water use, accelerate the flow of assimilates to storage organs, enhance resistance and disease resistance. Increase production. In recent years, the results show that potassium in plant physiology has many roles. First, potassium is a variety of enzyme activator potassium and nitrogen and phosphorus compared to potassium in the cells and the entire plant is very active, it is easy to use water extracted from plant tissues. Potassium is involved in many metabolic reactions due to its loose association with organic molecules and high activity. There are three types of enzymes that are activated by potassium: synthase, oxidoreductase, and transferase. Potassium is indispensable in the synthesis process and in various energy metabolism reactions. These enzyme reactions are particularly demanding for potassium,
