The role of potash fertilizer

1. Promoting enzyme activation is very important for plants. Potassium can ensure the normal growth and development of crops, increase the content of protein, promote the formation of sugar and starch, promote the synthesis of protein and cellulose.

2. Potassium can promote the transportation of photosynthesis, and the dry matter potassium produced by leaves can promote his transportation and increase the yield. Another kind of potassium fertilizer can regulate stomatal movement, that is, when the economic water of crops is dry, it is beneficial to increase the application amount of potassium fertilizer, which can be said to improve the drought resistance of crops. Another plant needs the activation of more than 60 enzymes.

3. Potassium fertilizer can be combined with iron fertilizer, that is, when plants have iron deficiency symptoms, increasing the amount of potassium fertilizer can promote the absorption of potassium fertilizer.

4. Potassium can adjust the concentration of cell fluid and the permeability of cell wall, and improve the ability of crops to resist diseases and insect pests, drought and cold. Promoting early nodulation of leguminous crops can improve nitrogen fixation ability, and potassium can enhance the disease resistance, cold resistance, drought resistance, lodging resistance and salt resistance of crops, improve the quality of crop products and increase the protein content of grain crops.

5. Potassium fertilizer can make the stems of trees stout, improve the ability of resisting diseases and insect pests, cold, drought and lodging, promote root development, expand bulbs, promote fruit expansion and have good color.
