How to judge whether vegetables are deficient in potassium? What about potassium deficiency in vegetables? How to supplement potassium? Wait, these are the knowledge points that growers need to know when planting vegetables. Next, Xiaobian will explain these questions one by one, and I hope that it will help everyone. First, the symptoms of potassium deficiency in vegetables 1. The edges of the leaves of the vegetables will turn yellow, and then there will be burning. 2. The middle leaves, veins and near veins of the vegetables are green. 3, vegetable roots are small but short, easy to fall. 4, vegetable fruit growth and development is poor, the fruit will also appear uneven coloration. Second, the role of potassium in crops? 1. Promote photosynthesis and increase the absorption and transformation of carbon dioxide by crops. 2. Promote the metabolism of sugar, which is beneficial to the growth and development of various tissues and improve the quality of crop products. 3. Participate in the regulation of cell fluid concentration and cell wall permeability, and improve the ability of crops to resist pests and diseases and drought environment. 4. Promote the absorption and utilization of water by roots. 5. Enhance the ability of crops to resist drought, high temperature, cold, disease, salt and lodging. Third, the reasons for the lack of potassium in vegetables 1. Failure to timely add potassium, resulting in low potassium content in the soil. 2. The demand for potassium fertilizer is relatively high during the fruit-bearing period of the crop. If the potassium fertilizer is not supplemented in time, the supply of potassium will be insufficient. 3. Lime fertilizer is used too much, affecting the absorption of potassium by crops. 4, the temperature is low, the sunshine is not charged in real time, it will affect the absorption of potassium by crops. Fourth, the method of potassium supplementation of vegetables 1. Apply more organic fertilizer and mix it with inorganic potassium fertilizer. 2. In special cases, potash should be applied in depth or layered. 3. Increase the application of potassium fertilizer during the period. 4, in the fruit or the ball period, with the application of foliar fertilizer.
