Correct use of potassium dihydrogen phosphate:
1. Applicable Crops of Potassium Dihydrogen Phosphate
Food crops: rice, wheat, maize, peanuts, beans, sorghum, rape, cotton, etc.
(2) Fruit trees: apples, pears, peaches, grapes, apricots, hawthorns, persimmons, citrus, jujubes, wolfberries and other northern and southern fruit trees.
Vegetable plants: tomatoes, cucumbers, peppers, beans, leek, eggplant, squash, garlic and other vegetables.
Economic plants: tea, sugar beet, sugarcane, hemp, watermelon, melon, Hami melon, strawberry, edible fungi, flowers, traditional Chinese medicines, etc.
Flowers and plants: peony, green radish, fortune tree, potted fleshy plants, tubular plants, herbaceous plants and so on.
2. Concentration and proportion of potassium dihydrogen phosphate
(1) Leaf spraying, 1000-1500 times water application, spraying 3-4 times in the middle and later stages of plant growth and development, 7-10 days spraying once.
(2) Root irrigation, tuber and tuber plant growth prophase, with 1500 times solution irrigation on the root of the plant.
(3) Soak seeds, mix 200 times water into a solution, soak seeds for 18-20 hours, remove them and dry them before sowing.
3. Application of potassium dihydrogen phosphate:
(1) Leaf spraying: spraying 2-3 times in the middle and late stages of crop growth and development, 7-10 days apart, the fertilizer dilution concentration was 2,000-6,000 times according to different crop species and growth period.
(2) Irrigation: 10,000 to 2,000 times dilution, uniform irrigation on the root of crops, can be used for irrigation, irrigation, dew irrigation, drip irrigation and so on.
Base application: mix 6-10 bags per mu with 10 kg fine soil or farm manure.
(4) Soaking and seed dressing: soaking seeds with dilution concentration of 2000 times for 18-20 hours and sowing seeds after shade drying. The solution used for seed soaking can still be used for foliar spraying or root irrigation. 0.5-1% water solution mixed seeds, 2-4 hours later can be sown.
