Potassium dihydrogen phosphate is also a high-concentration, high-quality chlorine-free potassium fertilizer with extremely low salt value and high nutrient content. It is suitable for use on a variety of crops. It not only promotes fruit expansion, color change, and crop metabolism, but also improves crop rooting, frost resistance, and stress resistance.
The specific functions of potassium dihydrogen phosphate
1.Promote nitrogen and phosphorus absorption
Potassium dihydrogen phosphate can promote the absorption of nitrogen and phosphorus by crops, quickly replenish phosphorus, increase crop yield and thousand-grain weight, and can play a special role in the special physiological period of crops.
2.Promote photosynthesis
Potassium plays a role in enhancing crop photosynthesis during crop growth and accelerating the production and transformation of nutrients.
3.Improve crop stress resistance
Potassium dihydrogen phosphate can improve the stress resistance of crops, such as drought resistance, dry and hot wind resistance, waterlogging resistance, frost resistance, damage resistance and healing, and resistance to pathogenic infection, etc.
4.Improve fruit quality
Spraying during the fruit expansion period can protect and strengthen the fruit, promote fruit expansion, improve fruit quality, increase coloring, and improve taste.
5.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, make the flower buds strong, strengthen the flowers and preserve the fruits, improve the fruit setting, and can also effectively promote the growth and development of the root system.
The useage of potassium dihydrogen phosphate
Potassium dihydrogen phosphate is also very convenient to use. It can be used as a base fertilizer, top dressing and foliar spray. Among them, base fertilizer is a fertilizer applied before crop sowing, which can provide long-lasting nutritional support for crops; top dressing is fertilizer applied during crop growth, which can provide timely nutrient supplement to crops; foliar spraying is to combine dihydrogen phosphate with Potassium is dissolved in water at a certain concentration and then sprayed on the leaves of crops. It can directly act on the leaves and branches of crops to promote photosynthesis and nutrient absorption.
1. Flush application: The dosage per mu is generally 1-3 kg.
2. Seed soaking: The concentration is generally 0.2%, that is, 100g of potassium dihydrogen phosphate mixed with 50kg of water. After soaking the seeds for 10-18 hours, take them out and dry them before sowing.
3. Seed dressing: The concentration is generally 1%, that is, 100g of potassium dihydrogen phosphate mixed with 10kg of water, sprinkle it on the seeds and mix well, dry it before use.
4. Foliage spray: During the crop growth period and early flowering period, use 50g of potassium dihydrogen phosphate mixed with 15 kilograms of water for foliar spraying on one acre of land. During the fruit setting, fruit expansion, and coloring stages, use 100g-200g of potassium dihydrogen phosphate mixed with water. 30 kg of foliar spray is applied to one acre of land.
Potassium dihydrogen phosphate usage range
Rice, wheat, corn, cotton, soybeans, peanuts, citrus, watermelon, apple, grape, hawthorn, banana, mango, lychee, longan, kiwi, jujube, pear, strawberry, loofah, tomato, beans, eggplant, pepper, spinach, Leeks, potatoes, edible fungi, medicinal materials, flowers, lawns, tea, tobacco, etc.
Precautions when using potassium dihydrogen phosphate
1.When using potassium dihydrogen phosphate at high concentrations, be sure to avoid high-temperature times. Generally, high-concentration use is not recommended in high-temperature seasons.
2.Potassium dihydrogen phosphate should be sprayed before 10 a.m. and after 4 p.m.
3.Potassium dihydrogen phosphate can be mixed with acidic and neutral pesticides to increase the efficacy, but cannot be mixed with alkaline substances.
4.Potassium dihydrogen phosphate is a fully water-soluble fertilizer and dissolves when exposed to water. Please store it in a cool and dry place. Please seal the opened bag before use.
5.Purchase from regular manufacturers, such as high-purity food-grade potassium dihydrogen phosphate produced by Huaken, Hunan. High-purity potassium dihydrogen phosphate has a high absorption and utilization rate when sprayed on foliage, and is absorbed quickly; inferior products with low purity or even fake products not only have no effect on increasing production, but also cause serious losses.
