Potassium dihydrogen phosphate is a high-efficiency phosphorus and potassium compound fertilizer in agriculture. The content of phosphorus and potassium is very high. It has a great effect on promoting flower bud differentiation of plants, prolonging the flowering period, and brightening the color. The potassium element can also make the stem and stalks thick and prevent lodging. Although it has many benefits for plants, we must use it strictly according to the packaging instructions, otherwise it will not only promote plant growth but also cause damage to plants.
Time : Potassium dihydrogen phosphate is mainly used to promote flowering, so it is generally used in the flowering period. It can promote early flowering and multi-pregnancy buds during pregnancy, and use it during flowering to make the flowers bloom more beautiful and lasting. Ye Hongshi microbial inoculant has better effect.
Use concentration and frequency
The concentration generally used is 0.2%. The concentration should not be too high or it will easily cause fertilizer damage. It is used every 7-10 days during flowering.
Potassium dihydrogen phosphate is dissolved in water and can be sprayed on the foliar surface or watered. The common method is to spray on the foliar surface. When spraying on the leaf surface, it is better to spray on the back of the leaf to absorb the effect, pay attention to avoid flowering buds and blooming flowers. Do not mix with urea when spraying, otherwise it will deteriorate the physical properties and cause a large loss of nutrients. Because potassium dihydrogen phosphate is acidic, and urea itself is neutral, but it is alkaline when dissolved in water. When mixed, if potassium dihydrogen phosphate solution and urea are mixed and used, the acid and alkali And, the fertilizer effect of both will be reduced.
