JINMAI-Damanguan® is a premium series of ultra-high potassium and phosphorus water-soluble fertilizers, designed for use during critical stages of crop development such as flower bud differentiation, fruit expansion, and ripening. Enriched with boron (B) and zinc (Zn), the formula ensures complete micronutrient support. It also contains natural cytokinins, ascophyllum nodosum extract, and gibberellins, which promote fruit cell elongation and division for improved size, color, and sweetness.
This product is available as white crystalline or powder, with low humidity (<0.5%) and high solubility (insoluble matter ≤0.2%). It is particularly suitable for improving acidic soils by adjusting pH through alkalinity.
Technical Indicators
Formula | Efficacy |
0-0-55-0.1B-0.1Zn | Promote the accumulation of dry matter in the fruit, optimize the color of the fruit, and promote the accumulation of sugar |
0-45-45-0.1B-0.1Zn | Promote flower bud differentiation,accelerate fruit dry matter accumulation, and promote fruit color change |
0-52-34 | Promote flower bud differentiation,regulate crop growth, and promote fruit expansion |
Key Features
Product Efficacy
⦁ Promotes Fruit Swelling and Color Change
High potassium levels improve fruit size, coloration, and sweetness.
⦁ Supports Flower Bud Differentiation
Phosphorus aids early reproductive development and bud formation.
⦁ Enhances Sugar & Dry Matter Accumulation
Optimizes fruit quality and increases yield during the expansion stage.
⦁ Improves Soil Conditions
Alkalinity helps neutralize acidic soils and improve root zone environment.
Applications
 | 0-0-55 + 0.1B + 0.1Zn ⦁ Suitable Crops: Grape, citrus, banana, apple, mango ⦁ Function: Promote dry matter and sugar accumulation, improve color ⦁ Best Timing: Mid to late fruit expansion stage |
 | 0-45-45 + 0.1B + 0.1Zn ⦁ Suitable Crops: Tomato, melon, peach, litchi ⦁ Function: Flower bud differentiation and early fruit growth ⦁ Best Timing: Pre-flowering to early fruit set |
 | 0-52-34 ⦁ Suitable Crops: Strawberry, cherry, mango, dragon fruit ⦁ Function: Regulate growth, promote fruit expansion ⦁ Best Timing: Early to mid fruit expansion stage |
Method Of Use
Method | Phenological Period | Dosage | Frequency |
Fertigation (drip/micro spray) | Fruiting period - Fruit expansion period | 5–15 kg/ha | Every 7–10 days |
Foliar Spray | 2–3 kg/ha (Dilute 500-800 times) | Every 10–15 days (Use 2-3 times continuously) |
Note: The specific usage and dosage can be adjusted according to the differences in regions, crop types, yields, etc, under the advice of technical personnel.
