| Efficient Potassium Source | K₂O≥170g/L, high-concentration potassium promotes sugar accumulation | Fruit expansion to maturity stage |
| Phenylalanine | Phenylalanine≥120g/L, precursor of anthocyanin synthesis | Fruit Coloring Stage |
| Fully Water-Soluble | Transparent liquid, dissolves quickly, no sediment | Foliar spray, drip irrigation |
Applicable Scenarios
Application Reference
Drip irrigation application (recommended)
Fully water-soluble alkaline liquid formula, especially suitable for facility agriculture and precision fertilization, promoting fruit sugar accumulation and coloring.
- Concentration: 0.5 – 1 L/acre of irrigation water
- Application rate: 5 — 10 L/acre/application
- Frequency: every 7 – 10 days
- Note: Can be used with water-soluble fertilizer containing macroelements
Foliar Spray
Rapidly supplies potassium and phenylalanine, promoting fruit coloring and sweetness, ideal for use during the fruit coloring stage.
- Dilution Ratio: 1:500 — 1:1000
- Application rate: 30 — 60 L/acre
- Time: morning or evening, avoid high temperatures
- Note: 2-3 consecutive sprays during the coloring period for best results
Fertigation
Apply via fertigation with watering to supplement potassium nutrition in fruit trees, vegetables, and other cash crops.
- Dosage: 10 — 15 L/acre/application
- Dilution Ratio: 1:100 — 1:200
- Timing: critical fruit coloring stage
- Note: Smaller, more frequent applications yield better results
Water-Soluble Fertilizer Blending
Use as a potassium source in combination with water-soluble macroelement fertilizers for balanced nutrition.
- Use with water-soluble macro-element fertilizer
- Addition ratio: 5 – 10%
- Suitable for melons, vegetables, and fruit trees
- Can be used alone or in combination with other amino acid products
Suitable crops and recommended dosage
| Crop Type | Representative Crops | Drip irrigation dosage | Foliar Spray Dosage | Application Period |
|---|---|---|---|---|
| Fruit Trees | Apples, pears, peaches, grapes, citrus | 3 — 5 kg/mu | 1000 – 2000 times dilution | Young fruit stage, expansion stage, post-harvest |
| Vegetables | Tomato, cucumber, pepper, eggplant | 2 — 4 kg/mu | 1000 – 1500 times dilution | Seedling, flowering, and fruiting stages |
| Melons and Fruits | Watermelon, melon, strawberry | 2 — 4 kg/mu | 1000 – 1500 times dilution | Vine extension stage, flowering stage, expansion stage |
| Oil Crops | Rapeseed, Peanut, Soybean | 2 — 3 kg/mu | 1000 – 1500 times dilution | Flowering and Podding Stages |
| Root & Tuber Crops | Potato, carrot, beet | 2 — 3 kg/mu | 1000 – 1500 times dilution | Tuber formation and expansion stage |
- Store in a cool, dry place away from direct sunlight. Use promptly after opening.
- This product is an alkaline liquid. Avoid direct mixing with strong acidic substances.
- Can be mixed with most fertilizers and pesticides, but small-scale testing is recommended before use.
- For foliar application, it is recommended to conduct a small-scale test first to confirm no phytotoxicity before large-scale use.
- It is recommended to filter the solution before drip irrigation to prevent nozzle clogging.
Frequently Asked Questions
The coloring period is critical for fruit quality formation, where potassium and phenylalanine function as follows:
- PotassiumPromotes sugar accumulation and transport, provides raw materials for anthocyanin synthesis, and supports fruit enlargement.
- PhenylalanineDirect precursor for anthocyanin synthesis, providing material basis for fruit red pigment formation
- Synergistic effectPotassium promotes sugar accumulation, and phenylalanine provides pigment precursors, together enhancing fruit color and sweetness.
Adequate supply of potassium and phenylalanine during the coloring period can significantly enhance fruit sweetness and color.
The main difference lies in nutrient form and additional effects:
- Common Potassium FertilizerExists in inorganic salt form (e.g., potassium chloride, potassium sulfate), providing only potassium nutrition
- Potassium Amino Acid Color Change LiquidUses amino acids as carriers for potassium ions, while containing phenylalanine, offering dual effects of potassium supplementation and coloring promotion
At the same time, amino acids themselves can improve crop stress resistance and fruit quality. This product is in liquid form for easier use.
Best results when used during fruit coloring period:
- Expansion PeriodUse from the young fruit expansion stage to promote sugar accumulation
- Early Coloring StageApply when color begins to change to promote pigment accumulation
- Full Coloration PeriodUse during rapid fruit coloring stage to improve uniformity and speed
- 15-30 days before maturityApply at the final stage to improve fruit sweetness and color
Recommended to use 2-3 times consecutively, with 7-10 day intervals.
