Potassium is one of the essential elements for plant growth and development. It is high in plant content and widely distributed. It is one of the most mobile elements. It is mainly in the form of ionic or soluble potassium. It is most active in life. In organs and tissues. Potassium can promote the utilization of light energy, enhance photosynthesis, and promote the operation of photosynthetic products. Potassium is an important quality element and has many effects on improving crop quality. For example, potassium can increase the length of cotton fiber. Potassium can also increase crop resistance, promote the development of crop epidermal tissue and vascular tissue, strengthen cell water holding capacity, reduce plant transpiration, thereby enhancing crop drought resistance; potassium can increase sugar reserves in crops, increase cell osmotic pressure, and enhance Cold resistance of crops.
