Application amount of potassium dihydrogen phosphate

Potassium dihydrogen phosphate is a kind of phosphorus and potassium compound fertilizer, which is widely used in all kinds of cash crops, grain, melons and fruits, vegetables and so on. So how much is the application amount of potassium dihydrogen phosphate?

What is the use of potassium dihydrogen phosphate?

Potassium dihydrogen phosphate is a chemical, which is used as high efficiency phosphorus and potassium compound fertilizer in agriculture. Potassium dihydrogen phosphate has many excellent functions, such as significantly increasing yield and income, improving quantity and optimizing quality, resistance to lodging, resistance to diseases and insect pests, prevention and control of premature senility, and can overcome the nutritional deficiency caused by the decline of root aging and absorption capacity in the later stage of crop growth.

Potassium dihydrogen phosphate is a new type of high concentration phosphorus and potassium two-element compound fertilizer, which contains about 52% of phosphorus pentoxide and 34% of potassium oxide. Flue-cured tobacco needs a large amount of phosphorus and potassium, especially potassium. Potassium dihydrogen phosphate is an ideal new fertilizer for flue-cured tobacco.

II. Application amount of potassium dihydrogen phosphate

The concentration of potassium dihydrogen phosphate is 0.1%-0.3%, that is, 15%-45 g potassium dihydrogen phosphate mixed with water 15kg, the amount of solution sprayed each time is 30-50kg per mu, once every 10-15 days, and 2-3 times is appropriate.

III. Dosage of other uses of potassium dihydrogen phosphate

1. Foliar spraying

1g potassium dihydrogen phosphate mixed with water 300-400g, stir well, then spray to the leaves of the plant. Use once every 10 days.

When spraying, spray once, there is no need to spray back and forth, if the plant is in the flowering period, potassium dihydrogen phosphate can not be used.

2. Field crops

10g potassium dihydrogen phosphate mixed with water 7-9 jin, stir well and pour it on the crops, usually once every 20 days.

When using potassium dihydrogen phosphate, be sure to wait until potassium dihydrogen phosphate is fully melted before use.
