The main function of phosphorus is the main nutrient for the enlargement of roots, stems, leaves and fruits, and it is the energy for cell division. Phosphorus fertilizer can be divided into chemical phosphate fertilizer and natural phosphate fertilizer. The main inorganic fertilizers synthesized by chemical or synthetic methods are calcium superphosphate and TSP. Phosphates are the main inorganic fertilizers that occur naturally.
Processing Technology of Phosphate Fertilizer
Phosphate fertilizer is made from fish bones, bones, eggshells, freshwater fish scales, cut hair, nails and so on. Phosphate fertilizer can be divided into water-soluble phosphate fertilizer, citric acid-soluble phosphate fertilizer and insoluble phosphate fertilizer according to its solubility. Phosphate fertilizers are classified into wet and hot methods according to production methods.
Granulation Machine of Phosphate Fertilizer
Rotary drum granulator
: It is suitable for granulation of organic and inorganic substances and is widely used in production line.
Drum screener Machine
: Drum screener machines are commonly used equipment in the production of fertilizers to separate materials and finished products. The sifter features an integrated screen for easy repair and replacement.
Other supporting facilities: We have mixing machines of different specifications and functions. Vertical mixers
are commonly used in the production line of inorganic materials.
Problems in Phosphate Fertilizer
1．The most direct symptoms of phosphorus deficiency are crop vary in size in the field, especially in orchards. Most fields will also behave like this now. Leaf surface at the top of a plant is small and purple.
2．Zinc fertilizer and phosphorus fertilizer can not be mixed. If zinc fertilizer and phosphorus fertilizer are mixed together, zinc phosphate, which is not easy to dissolve in water, will be formed. Zinc phosphate crop is very difficult to absorb and can not achieve the desired effect.
3．Excessive nutrients such as iron, zinc and nitrogen in soil can inhibit the absorption of phosphorus fertilizer.
4．When the PH value is 5.5, the absorptivity is only about 15% of PH value 6.5.
5．The absorptivity at 13 degrees is only 31% at 21 degrees.
Solutions to Phosphate Fertilizer Problems
1．Improve the soil, apply more organic fertilizer (supplement microorganism), and regulate the PH value of soil.
2．Spraying phosphorus fertilizer on the leaf surface is not restricted by the above conditions, and the absorption is more direct.
3．Pay attention to balanced nutrition and fertilization.
