---

Phosphate fertilizers can mainly include three major types. One is water-soluble phosphate fertilizer, which is ordinary superphosphate and calcium phosphate. The characteristic is that it is easier to dissolve in water and has a faster fertilizer effect. The second is citrus-soluble phosphate fertilizer. The fertilizer effect is slower than the first type, and the soil environment used is different, so it is more suitable for acidic soil. The third is insoluble phosphate fertilizer, common bone meal, phosphate rock powder, suitable for strongly acidic soil, insoluble in water, fertilizer effect is slow, but the aftereffect is relatively long.

1. Types of phosphate fertilizers

1. Water-soluble phosphate fertilizers: Water-soluble phosphate fertilizers refer to ordinary superphosphate, calcium phosphate, such as monoammonium phosphate, diamine phosphate, etc. The main ingredient contained in it is monocalcium phosphate, which is more easily soluble in water and has a faster fertilizer effect. Usually used in various soils and crops. But it is more recommended to be used in calcareous soil and neutral soil.

2. Citrus soluble phosphate fertilizer: It refers to calcium magnesium phosphate fertilizer , precipitated phosphate fertilizer, calcium hydrogen sulfate, etc., the main component of which is dicalcium phosphate. Its fertilizer effect is slower than the first one, and the soil environment used is different, so it is more suitable for acidic soil.

3. Insoluble phosphate fertilizer: The most common ones are bone meal and phosphate rock powder, whose main component is tricalcium phosphate. Suitable for strongly acidic soil and insoluble in water. After application, it can only be dissolved by the acidity in the soil and turned into a form that can be used by crops and plants. Its fertilizer effect is slow, but the aftereffect is long, and it is suitable as a base fertilizer in acidic soil.

2. The role of phosphate fertilizer

The role of phosphate fertilizer is mainly reflected in four aspects. First, it can promote the respiration of crops and the absorption of nutrients and water, thereby improving water use efficiency and short-term drought resistance. Second, it can promote crop protein, carbohydrate and fat metabolism, thereby promoting earlier crop maturity. Third, it can promote cell division, thereby accelerating root growth. Fourth, it can enhance the stress resistance of crops, especially drought resistance, cold resistance, and disease resistance.
