High concentration of liquid fertilizer

    Excessive concentration of liquid fertilizer often leads to the yellowing of flowers and leaves, and even the entire plant. What is the reason for this? Because under normal circumstances, the concentration of the plant root hair cells was greater than the concentration of the soil solution, thus the two different osmotic pressure, then the soil solution to the root hair cells can be continuously permeated, from the root hairs absorb water and nutrients in the soil, Supply flowers for growth and development. If the concentration of the liquid fertilizer is too high (the concentration is greater than the concentration of the cell liquid), the opposite phenomenon occurs, that is, the cell liquid penetrates into the soil solution, causing the root cells to lose water, causing the separation of the walls, and causing the plants to wither and die in severe cases. The reason is similar to that of pickled vegetables in the family. Put the salt and vegetables into the water tank. It doesn't take long for the salt water to fade and the vegetables become wilted. This phenomenon often occurs when there is too much fertilizer, and a similar phenomenon occurs if the liquid fertilizer is too thick. Therefore, the concentration of potted fertilizer solution should not be too high, generally about 0.1% . Also required is diluted 5 to 10 times when properly administered fertilizer retting.
