摘要
钾是作物生长必需元素,在维持细胞内物质正常代谢、酶活性增加,促进光合作用及其产物的运输和蛋白质合成等生理生化功能方面发挥着重要作用。综述了钾对马铃薯生长发育进程及产量、品质形成的影响,总结了不同钾源对马铃薯的影响,并进行了展望。
Potassium is an essential element for crop growth, which plays an important role in maintaining normal material metabolism, increasing enzyme activity, promoting photosynthesis and transportation of photosynthate, promoting protein synthesis. In this article, effects of potassium on growth and development, yield and quality of potato were summarized, and the research directions were prospected.
