What are the common kinds of compound fertilizers? What are the functions?
Compound fertilizer is often used in the process of agricultural production, and it has always been the key to the high yield of crops. to a certain extent, it can promote the growth of vegetables or fruits and achieve high yield, and the nature of compound fertilizer is relatively stable. so what are the common types of compound fertilizer? What's the use? Let's get to know it next.
1. Ammonium phosphate
The property of ammonium phosphate is relatively stable and is suitable for all kinds of soil and crops. when it is used as base fertilizer, it should be combined with nitrogen fertilizer, and it should not be too close to the root, and special attention should be paid to avoid mixing with alkaline fertilizer, because they will undergo chemical reactions and lose their fertilizer effect.
2. Phosphorus nitrate
Phosphorus nitrate has strong hygroscopicity and is easy to decompose in the presence of alkali, and its components are ammonium nitrate, calcium nitrate, ammonium phosphate and dicalcium phosphate. It is not recommended to be used in paddy fields and legume crops. It is generally used as base fertilizer and topdressing, and the fertilizer effect of ammonium phosphate fertilizer is better than that of nitrophosphate fertilizer. Ammonium phosphate fertilizer can be used when growing crops such as rice.
3. Potassium nitrate
Potassium nitrate is soluble in water, flammable and explosive. It is mainly used for seed soaking or foliar spraying. It is very suitable for potassium-loving crops, such as tobacco and grapes.
4. Potassium dihydrogen phosphate
Potassium dihydrogen phosphate is soluble in water and is often used for foliar fertilizer spraying and seed soaking. it has a wide adaptability, plays a key role in improving fruit yield and strong seedlings, and can improve crop resistance, and can also be used alone in crop flowering and fruit forming stages. If it is used for drip irrigation, sprinkler irrigation or irrigation, just pay attention to the concentration, but should not be mixed with alkaline pesticides.
To sum up, this is the end of the introduction of common types of compound fertilizer. If you want to use compound fertilizer to increase crop yield, you should do a good job of scientific fertilization. Avoid all kinds of fat damage.
