Spraying: 400 grams per acre in the pre-greening period, pre-union stage, pre-pregnancy stage, pre-flowering stage, and pre-grouting stage, sprayed 75-150 times of water fully dissolved. Fill the 14 to 16 kg sprayer tank with water, add 100 g (150 times) or 200 g (75 times) of potassium dihydrogen phosphate, then shake for 5 to 10 minutes, so that it can be fully dissolved and sprayed. Do not leak, do not drop.
Washing: During a certain growth period, if it is applied during watering, the dosage can be increased to 3 kg, and the yield increase will increase, but attention should be paid to uniformity. Calculate the amount of each cockroach first, then dissolve it in 10 times of water. When watering, place half of the solution in the water inlet of the concrete. With the water, place the remaining half of the solution in the third place of the long-distance water inlet with water.
Note: Potassium dihydrogen phosphate can be mixed with acidic pesticides during the sowing period. The number of sprays can be increased depending on the situation at each application period. Do not spray on rainy days and in the sun.

Superconstant potassium application of potassium dihydrogen phosphate
The super-constant application of potassium dihydrogen phosphate can significantly increase the yield of wheat. The method is: seed dressing: 100-200 grams of potassium dihydrogen phosphate per acre. Each 5 kg of seeds is 500 to 600 g of water, and the water temperature is 20 ° C to 25 ° C. The weighed potassium dihydrogen phosphate was added to the vessel and stirred to sufficiently dissolve the potassium dihydrogen phosphate. Sprinkle the prepared solution in the weighed wheat seeds and mix well. Then pile them together, leave them for 5 hours, dry them (to stick to the hands) and sow them.
