Ammonium dihydrogen phosphate is a kind of binary compound fertilizer, and it is also a high-concentration compound fertilizer. It is generally used as a top dressing. So what are the effects of ammonium dihydrogen phosphate on plants?
1. Basic introduction of diammonium phosphate
Diammonium phosphate refers to a chemical substance whose standard product contains N18%, P2O548%, crystalline shape is flat oblique prism, solubility in 25C water is 71%, and the pH of its saturated solution reaches 8.
Diammonium phosphate, also known as diammonium hydrogen phosphate (DAP), is a compound fertilizer containing nitrogen and phosphorus. Gray-white or dark gray particles, specific gravity 1.619, easily soluble in water, insoluble in ethanol. It has a certain hygroscopicity and is easily decomposed in humid air, and volatilizes ammonia into ammonium dihydrogen phosphate.
Diammonium phosphate is a high-concentration quick-acting fertilizer, suitable for various crops and soils, especially for crops that like nitrogen and phosphorus.
Second, the effect of ammonium dihydrogen phosphate on plants
Function 1. The total nutrient content is more than 73%, of which the phosphorus content is more than 61%, and it does not contain chlorine, sodium, calcium and heavy metals. The phosphorus element provided is more effective and safer.
Function 2. It contains a low nitrogen and phosphorus ratio, so it is suitable for all crops and their seedling growth stages to promote rooting and strong seedlings. It can also be mixed with various water-soluble fertilizers such as urea, potassium nitrate, potassium sulfate, etc., so as to meet the nutritional needs of more plants in each growth period.
Function 3. Ammonium dihydrogen phosphate solution is weakly acidic, which is convenient for flushing, spraying, drip irrigation and fertilization. Provide high-efficiency phosphorus source for seedlings, which is conducive to cultivating strong seedlings. Promote root growth, help slow seedlings and improve plant resistance.
Function 4. It can be mixed with various water-soluble fertilizers such as urea, potassium nitrate, potassium sulfate, etc., so as to meet the nutritional needs of more plants in each growth period.
