Application of Potassium Dihydrogen Phosphate in Agricultural Crops

1, wheat application method

In the early stage of returning green, early jointing stage, early stage of booting, early stage of flowering, and early stage of filling, 400 grams per acre is applied, and sprayed with 75-150 times of water is fully dissolved.

2. Rape application method

In the pre-emergence and post-emergence stage, potassium dihydrogen phosphate (ammonium dihydrogen phosphate monobasic) is sprayed twice, and 200 g of potassium dihydrogen phosphate (including potassium dihydrogen phosphate) is mixed with 30 kg of water per acre. Potassium dihydrogen phosphate (ammonium dihydrogen phosphate) Second time 400g water per acre 30kg, flowering to maturity stage, once every 10 days spraying potassium dihydrogen phosphate (ammonium dihydrogen phosphate), each 800 grams of water per acre 50 kg. The performance is seedlings full, less disease, and a large increase.

3, tea application method

Spray once every 7-10 days in the growth period of tea, with a concentration of 0.3%, about 50-100 grams per acre of potassium dihydrogen phosphate (ammonium dihydrogen phosphate) (potassium dihydrogen phosphate (ammonium dihydrogen phosphate) Ammonium) can effectively resist drought, cold, yellow leaves and other diseases, and can greatly increase the yield and quality of tea.

4. Method of supernormal application of vegetables such as cucumbers, tomatoes, beans, and eggplants

The seedling stage was sprayed twice with 1% potassium dihydrogen phosphate (ammonium dihydrogen phosphate). When transplanting, dilute potassium dihydrogen phosphate (ammonium dihydrogen phosphate) containing 1% of the liquid can be used to immerse the roots or irrigate the roots, and the seedlings can be sprayed twice at the pre-flowering stage, and potassium dihydrogen phosphate (including dihydrogen phosphate) is used for each acre. Potassium ammonium) 200 g water 30 kg, spraying every 7 days after fruit set, each with 400 grams of water per acre 50 kg.
