Product description
Product overview
Trehalose-based calcium-magnesium special fertilizer for fruit enlargement is a high-efficiency seaweed-based fertilizer specially designed for the fruit development stage. The product contains high concentrations of calcium, magnesium, boron, nitrogen, potassium, and other elements, produced using sugar alcohol chelation technology that freely transports various elements in xylem and phloem, significantly improving element uptake. Application on crops rapidly enlarges fruits, effectively increasing yield and fruit quality.
Key Advantages
Rapid fruit filling
Rich in nitrate nitrogen and highly efficient chelated potassium, promotes rapid fruit enlargement, effectively increases yield and fruit quality.
Prevention of fruit cracking
Rich in calcium with sugar alcohol, it quickly eliminates calcium deficiency symptoms in plants, increases fruit firmness, prevents cracking, and extends storage or shelf life.
Growth regulator
Rich in chelated boron and chelated magnesium, it balances vegetative and generative growth, enhances plant photosynthesis, and improves fruit set.
Quality improvement
Promotes protein and carbohydrate synthesis, effectively enhancing fruit quality, taste, and appearance.
Key Advantages
- High calcium contentCa≥140 g/L, effectively prevents physiological disorders such as fruit cracking and softening.
- Chelation technology with sugar alcoholsElements such as calcium, magnesium, and boron are in a chelated form based on sugar alcohols, offering good mobility and high absorption rates.
- Two-way transportationSugar alcohols are freely transported in xylem and phloem, significantly improving nutrient utilization efficiency.
- Rapid fruit fillingRich in nitrate nitrogen and highly efficient chelated potassium, rapidly promotes fruit enlargement.
- Complete NutritionComprehensive supplementation of five elements: calcium, magnesium, boron, nitrogen, and potassium for balanced nutrition.
- Extended shelf lifeIncreases fruit firmness, extends storage and shelf life.
Area of application
Application recommendations
Foliar Feeding (Recommended)
Rapidly replenishes nutrients required for fruit development, promotes fruit enlargement, and increases sugar content.
- Dilution ratio: 400 – 1000 times
- Spraying time: morning or evening
- Application site: upper and lower leaf surfaces
- Note: can be applied multiple times throughout the growing season
Fertigation and drip irrigation
Suitable for large-area fertilization, provides continuous nutrition and promotes fruit development.
- Dilution ratio: 800 – 1500 times
- Application interval: 7–14 days
- Number of applications: recommended 2–3 times.
- Note: Combine with irrigation for best effect
Suitable crops and recommended dosage
| Crop Type | Typical crops | Application method | Recommended dosage | Application interval |
|---|---|---|---|---|
| Vegetable Crops | Tomatoes, cucumbers, peppers, eggplants, legumes | Fertigation and drip irrigation | 5 – 15 kg/mu/application | 7-10 days/time |
| Fruit Trees | Apples, pears, peaches, grapes, citrus | Fertigation and drip irrigation | 15 kg/mu/application | 7-14 days/time |
| Melon and Gourd Crops | Watermelon, melon, strawberry | Foliar application/fertigation | 400-1000 times / 7.5-15 kg | 7-10 days/time |
| Other crops | Flowers, medicinal herbs | Foliar Feeding | 1000 times | As Needed |
- This product can be applied multiple times throughout the crop's growing season.
- Recommended application rate for vegetable crops: 7.5–15 kg/mu per application, with a 7–10 day interval.
- Recommended application rate for fruit trees: 15 kg/mu/application, every 7-14 days, 2-3 applications recommended.
- For foliar application, dilute 400-1000 times and spray evenly on both sides of leaves.
- For drip irrigation and fertigation, dilute 800-1500 times.
- Store in a cool dry place, avoid direct sunlight.
- Shake before use; use the diluted solution immediately.
- Compatible with most fertilizers and pesticides, but a small-area trial application is recommended before use.
- For foliar application, it is recommended to first trial on a small area to confirm no phytotoxicity, then use on large areas.
- Before use in drip irrigation, it is recommended to filter the solution to prevent clogging of drippers.
Frequently asked questions
Calcium, magnesium, and boron interact closely during crop fruit development:
- CalciumIt is a key component of the cell wall, increases fruit firmness, prevents cracking, and extends shelf life.
- MagnesiumIt is the central atom of chlorophyll, promotes photosynthesis, providing energy for fruit development.
- BoronPromotes sugar transport and metabolism, enhances translocation of photosynthetic products.
- SynergismThree components synergistically improve fruit set, protein and sugar synthesis.
The effectiveness of simultaneous application of calcium, magnesium, and boron is significantly higher than separate applications.
Sugar alcohol chelation technology offers the following advantages over conventional:
- Two-way transportationSugar alcohol-chelated elements are freely transported in xylem and phloem, ensuring more complete nutrient utilization.
- High StabilitySugar alcohols form stable chelates with nutrients that are not fixed by the soil.
- High bioavailabilitySugar alcohols themselves are organic substances that plants can directly absorb and utilize.
- Fast ActingSugar alcohols quickly deliver nutrients to cells, promoting rapid fruit enlargement.
Select optimal timing based on application purpose:
- Young Fruit StageStimulates cell division and development in young ovaries, laying the foundation for fruit enlargement
- Fruit Filling PeriodPromotes rapid fruit enlargement and increases yield
- Fruit coloring stagePromotes sugar accumulation, improves fruit quality and taste.
- Entire growing seasonCan be applied multiple times for continuous feeding
It is recommended to apply in advance during key crop calcium and boron demand periods; prevention is better than cure.
