Effect of Potassium Dihydrogen Phosphate
In order to improve crop resistance, low temperature resistance and lodging resistance, experiments were carried out on Brazilian banana seedlings, which showed that appropriate concentration of potassium dihydrogen phosphate could improve the low temperature resistance of banana seedlings.
Enhance the ability of anti-collision and natural decay of crops and prolong the storage and transportation period.
Because potassium dihydrogen phosphate is a compound fertilizer of phosphorus and potassium, spraying in the period of fruit enlargement can protect and strengthen fruit, promote fruit enlargement, improve fruit quality, increase coloring, improve taste and so on.
Spraying before and after flowering can promote flower bud differentiation, increase flowering number, strong bud, strengthen flower and fruit, improve fruit setting, and effectively promote root growth and development, and promote early ripening of crops.
At the same time, high-purity potassium dihydrogen phosphate is used in a variety of ways, such as spraying, irrigating, transplanting with dipping roots, soaking seeds, mixing seeds and basal application.
Finally, whether potassium dihydrogen phosphate contains chlorine depends on whether the source of potassium dihydrogen phosphate is potassium chloride or potassium hydroxide or other potassium sources. Generally, the content of chloride ion in industrial first-class products is limited, but the agricultural standards are not stipulated.
Application range of potassium dihydrogen phosphate:
Citrus, watermelon, apple, pear, grape, hawthorn, banana, mango, litchi, longan, date, kiwifruit, strawberry, rice, wheat, corn, cotton, soybean, peanut, luffa, tomato, bean, eggplant, pepper, spinach, leek, potatoes, edible fungi, medicinal materials, flowers, lawn, tea, tobacco, etc.
Matters needing attention:
When using phosphorus dioxide in high concentration, we must avoid high temperature time. In general, high concentration is not recommended in high temperature season. (Special attention)
It is advisable to spray it before 10 a.m. and after 4 p.m.
Phosphorus dioxide can be mixed with acidic and neutral pesticides to increase its efficacy, but not with alkaline substances.
Phosphorus 2 is a water-soluble fertilizer. It dissolves in water. Please store it in a cool and dry place. Please seal the bags when they are not used.
