Product Features
1. Super strong chelating ability
- Chelated metal ions: Each 1g of product can chelate 15ml of 1% calcium nitrate solution (national standard value 13ml), effectively softening hard water and activating solidified trace elements (Fe/Zn/Mn) in soil;
- Corrosion protection: Form a passivation film on the metal surface to reduce equipment corrosion rate by more than 30% (applicable to industrial washing and irrigation systems).
2. Efficient dissolution and sustained release
- Dissolution rate: The solubility reaches 194g/100g water at 25 ℃ (three times that of potassium phosphate), and it is completely water-soluble with no residue;
- Long term fertilizer supply: gradually hydrolyzed into orthophosphate in the soil, with a release cycle of 20-30 days for phosphorus and potassium, and an increased utilization rate of 60%.
3. Dual application scenarios
area | Core values | Empirical effect |
---|---|---|
Agricultural fertilizers | Phosphorus potassium compound fertilizer+soil improvement | Salt alkali land production increased by 25%, and the sugar content of tuber crops increased by 2% |
food industry | Meat retains moisture and enhances tenderness, while dairy products resist clumping | Lunch meat production rate increased by 15%, resulting in improved taste |
Environmental protection field | Wastewater dephosphorization and denitrification, boiler descaling | Hard water softening efficiency>95% |
Usage and dosage
Agricultural applications
Application method | Dilution ratio/acre usage | critical period | effect |
---|---|---|---|
Drip irrigation | 800-1000 times | Flowering period → fruiting period | Prevent fruit drop and promote sugar accumulation |
Impulse | 5-8kg/acre | Tillering stage/tuber swelling stage | Root expansion ↑ 40% |
Jishi (fruit tree) | 0.3-0.5kg/plant | Deep application of autumn fertilizer 20cm | Enhance winter cold resistance |
Industrial applications
- Food processing: Add 3-5 ‰ (meat/dairy products);
- Water treatment: Add 0.1-0.5% according to the hardness of the water quality and recycle it.
Applicable crops and scenarios
category | Recommended crops | Pain point resolution |
---|---|---|
field crops | Rice, wheat, corn | Prevent premature aging during the grouting period, with a 1000 grain weight increase of 10% |
cash crop | Cotton, sugar beets, sunflowers | Salt alkali land volume recovery, fiber strength increased |
Fruits and vegetables | Grapes, citrus fruits, tomatoes, potatoes | Fruit cracking rate ↓ 50%, starch accumulation in tubers ↑ |
food processing | Luncheon meat, frozen fish and shrimp, condensed milk | Water retention ↑, loss of thawed juice ↓ 30% |
precautions
1. Safe operation
- Protection requirements: Wear goggles and dust masks during operation (contact with dust may irritate the respiratory tract);
- Prohibited substances: Strong acid (releasing highly toxic phosphine), copper agent (ineffective).
2. Storage specifications
- Environment: Humidity ≤ 80%, temperature < 30 ℃, cool warehouse, can continue to be used after clumping and crushing;
- Transportation: Moisture proof ton bag+lined with plastic film to avoid mixing with organic matter.
3. Agricultural application taboos
- Highly saline alkali soil: When the EC value is greater than 2.5mS/cm, the first dose is halved to prevent osmotic stress;
- Mixing restrictions: Avoid mixing with calcium fertilizers/strong alkaline pesticides (resulting in calcium phosphate precipitation)
Packing:Plastic woven bag. Net weight 25 Kg、 50Kg 、1000Kg , store at a cool, dry and well ventilated place.
