Potassium dihydrogen phosphate, used at these 3 time points, missed the result with half the effort!
Potassium dihydrogen phosphate is a widely used fertilizer with outstanding use effect. Knowing and mastering its efficacy characteristics and using it skillfully and correctly can achieve twice the result with half the effort. Let me share with you the use of dihydrogen phosphate that most people ignore.
The nutritional content of high-purity potassium dihydrogen phosphate is 52 phosphorus and 34 potassium. Phosphorus has a significant effect on the growth of roots, stems and peels of crops, and also has obvious effects in enhancing crop disease resistance, cold resistance and waterlogging resistance. Potassium has significant effects in increasing crop yield, increasing fruit quality and increasing sugar content.
Potassium dihydrogen phosphate must be grasped in several key periods when using it
The first is the flower bud differentiation stage
The demand for phosphorus is relatively large during the flower bud differentiation period, and phosphorus elements also have a very good effect on improving the flowering and fruit setting rate of crops and reducing flower and fruit drop. Therefore, spraying 500 times of potassium dihydrogen phosphate solution on the leaves during the flower bud differentiation period will have a multiplier effect.
The second is the fruit expansion period
Everyone knows that the fruit expansion period is when the demand for potassium is high. Potassium is irreplaceable for seed formation and fruit expansion, and crops are also sensitive to potassium at this time. The effect of root application or foliar application is obvious during this period. When spraying 500 times of potassium dihydrogen phosphate on the foliage, it can be mixed with 200 times of glucose and 1000 times of urea, which can achieve twice the result with half the effort.
The third is the coloring period
Fruit coloring is the process of anthocyanin formation, and the formation of anthocyanin has a direct relationship with sugar content and sunlight, and the formation of sugar substances is greatly affected by potassium. Therefore, the role of potassium plays a key role in the coloration of fruits. Therefore, the effect of spraying 300-500 times of potassium dihydrogen phosphate on the leaves in the early stage of fruit coloring is twice the result with half the effort.
But then again, with so many potassium dihydrogen phosphates on the market, which one is more cost-effective to buy?
Rizheng Agriculture's main content of potassium dihydrogen phosphate ≥99, water-soluble phosphorus pentoxide ≥52, potassium oxide content ≥34, the content conforms to various indicators, fully soluble in water, free of chlorine and hormones and other ingredients.
