The role of potassium dihydrogen phosphate
One
Promote nitrogen and phosphorus absorption. Potassium dihydrogen phosphate can promote the absorption of nitrogen and phosphorus by crops, quickly supplement phosphorus, increase crop yield and thousand grain weight, and play a special role in special physiological periods of crops.
Two
Promote photosynthesis. Potassium element enhances crop photosynthesis and accelerates nutrient production and transformation during crop growth.
Three
Improve crop stress resistance. Potassium dihydrogen phosphate can enhance the stress resistance of crops, such as drought resistance, resistance to hot and dry winds, resistance to floods, resistance to freezing, resistance to damage and promoting healing, and resistance to bacterial infections.
Four
Improve fruit quality. Spraying during the fruit enlargement period can protect and strengthen the fruit, promote fruit enlargement, improve fruit quality, increase coloring, and improve taste.
Five
Regulate crop growth. Potassium dihydrogen phosphate has the function of a regulator, which can promote the differentiation of crop flower buds, increase the number of flowers, have strong flower buds, strengthen flowers and preserve fruits, improve fruit setting, and effectively promote the growth and development of root systems.
Usage of potassium dihydrogen phosphate
One
Potassium dihydrogen phosphate is suitable for many types of soil and various food and economic crops, such as wheat, soybeans, corn, rice, vegetables, fruit trees, flowers, etc. It can also be used as a base material for other fertilizers.
Two
Potassium dihydrogen phosphate can be used for seed soaking, seed mixing, root soaking, root irrigation, foliar spraying, and root application, which has a significant increase in crop yield. Generally used as root dressing on field crops, wheat, soybeans, corn, rice, and other crops require a dosage of 1.5-2 kilograms per hectare; Generally, soaking seeds, dipping roots, root flushing, and leaf spraying are the main methods for economic crops such as vegetables, melons, and fruits.
Three
Soaking: 200 times the liquid, soaking for 18-20 hours; Dipping roots: 7.5 kilograms of potassium dihydrogen phosphate per hectare, mixed with an appropriate amount of water and dry soil to make a liquid slurry for dipping roots; Root irrigation: 1500 times solution irrigation for roots; Foliar spraying: 1000-1500 times spraying.
