Phosphorus Acid Dihydrogen Potassium as Flower Fertilizer
An introduction to the common knowledge of flower cultivation - phosphorus acid dihydrogen potassium as a flower fertilizer. Next, the editor will introduce it to the netizens.
Phosphorus acid dihydrogen potassium is used as a high-efficiency phosphorus-potassium compound fertilizer, suitable for various soils and crops. It is also used as a bacterial culture medium, a synthetic seasoning agent for clear liquor, a raw material for the production of metaphosphorus potassium, a culture medium, enhancer,膨松剂 (loosening agent), and fermentation aid for brewing yeast. It is used in medicine to alkalinize uric acid and as a nutrient. Food-grade products are used in the food industry to make baked goods, monosodium glutamate, and fermentation powder. Feed-grade products are used as beverage nutrients.
Application on crops such as wheat:
1. Application timing: In sandy and loamy soils that are deficient in phosphorus and potassium, phosphorus acid dihydrogen potassium can be applied at the time of land preparation. Before sowing, the seeds can be soaked in a solution of phosphorus acid dihydrogen potassium. During the wheat's tillering peak, green return stage, jointing stage, booting stage, and filling stage, top-dress with phosphorus acid dihydrogen potassium, with the filling stage being a must. In medium-loamy and clayey soils with higher phosphorus and potassium content, seeds can be soaked in a solution of phosphorus acid dihydrogen potassium and top-dressed during the green return stage, jointing stage, booting stage, and filling stage.
2. Application concentration: (1) Basic application. As a base fertilizer, 8-10 kilograms per mu of phosphorus acid dihydrogen potassium is recommended, combined with 25 kilograms of urea, to achieve a balanced ratio of nitrogen, phosphorus, and potassium. (2) Seed soaking. 200 grams of phosphorus acid dihydrogen potassium per mu is sufficient. (3) Foliar spraying. 300-700 grams per mu each time, diluted in 40-60 kilograms of water, with a spray concentration of 0.8%-1%.
3. Application method: For base fertilizer, mix phosphorus acid dihydrogen potassium with fine soil and spread it evenly during plowing, or mix it with nitrogen fertilizer and spread it evenly after application. For seed soaking, dilute the required amount of phosphorus acid dihydrogen potassium with water, stir well, ensure the liquid level in the container is 5 cm higher than the seeds, soak for 10 hours, and then dry before sowing. For foliar spraying, apply the mixed solution of phosphorus acid dihydrogen potassium evenly on the leaves on a windless and sunny morning before 10 am or in the afternoon after 4 pm.
The above is a complete introduction to phosphorus acid dihydrogen potassium as a flower fertilizer for everyone to learn and understand!
