Six major partners of potassium dihydrogen phosphate 1. Potassium dihydrogen phosphate+urea, quickly replenishes nutrients, enhances photosynthesis, promotes growth, and increases yield.The ability of urea to penetrate the cell membrane of leaves is very strong, and its permeability coefficient is close to that of water. As a top dressing fertilizer, urea should be the fastest absorbing fertilizer, and its fertilizer efficiency is also particularly fast. 0.3% urea and 0.3% potassium dihydrogen phosphate combined with foliar spraying can promote faster and better absorption of potassium dihydrogen phosphate by crop leaves, and the utilization rate of potassium dihydrogen phosphate is also greatly improved.2. Potassium dihydrogen phosphate+paclobutrazol, promoting flower bud differentiationApplying flower promoting agents during the flower bud differentiation period of fruit trees such as citrus (usually from November to Januar...
