Usage of potassium dihydrogen phosphate

Usage of potassium dihydrogen phosphate.

1. Time of use

The safety cycle of potassium dihydrogen phosphate application is generally 7-15 days, soaking seed and base application need not be said, the time of flushing can be used every 7-10 days, while the time of spraying can be sprayed every 10-15 days, a crop should not be sprayed too many times a season, in the key fertility period can be sprayed about 3 times.

2. Seed dipping

The use of potassium dihydrogen phosphate for seed dipping, can make the crop seed germination rate, so that early germination, early seedling, seedling flush, seedling strong, green leaves, more tillers, root system developed, etc.. In terms of dosage, a solution of 2g of potassium phosphate is generally used for 1kg of seed, which is then sprayed on the seed and dried. Soaking seeds can generally be made according to 50 kg of water plus 100 g of potassium dihydrogen phosphate solution (or according to 1 kg of seed + 20 g of potassium dihydrogen phosphate use), soaked through the seeds 2-3 inches soaked 12-16 hours, and then dried out to use.

3. Root dipping

Potassium dihydrogen phosphate is used for dipping roots and is used more often on flowering seedlings. In use, when the planting area is large, you can follow the dosage of 0.5 kg of potassium dihydrogen phosphate per mu, add the right amount of water and dry fine soil modulation into a liquid slurry dipped into the roots; for home planting of more flowers and seedlings, you can follow the 0.1% concentration dipped into the roots.

4. Foliar spraying

Potassium dihydrogen phosphate is more commonly used as a foliar fertiliser, with good results, and is generally mixed with various pesticides and fertilisers. The use of potassium phosphate on crops not only strengthens seedlings, trees, roots, flowers and fruits, but also enhances the resistance of crops (e.g. to drought, cold, disease and hot and dry winds), as well as quickly replenishing phosphorus and potassium nutrients, enhancing photosynthesis and accelerating the production of nutrients, which has a significant effect on the differentiation of flowers and buds and fruit development.
