Key Features
Product Efficacy
⦁ Root Promotion & Nutrient Uptake
Polyglutamic acid stimulates the growth of fine roots and new roots, while forming a protective film on root hairs. This increases the contact area between roots, water, and nutrients, enhancing uptake efficiency and reducing fertilizer loss.
⦁ Stress Resistance & Plant Vitality
Increases proline accumulation and metabolic activity, leading to better photosynthesis and resilience against drought, salinity, and temperature fluctuations.
⦁ Fruit Surface Beautification & Quality Improvement
Promotes sugar and terpenoid synthesis, balances plant hormones, repairs fruit surface damage, and improves fruit sweetness, color, and marketability.
Applications
 | Fruit Trees ⦁ Suitable Crops: Apple, pear, citrus, mango, grape, banana, etc. ⦁ Function: Promotes strong roots, increases sugar accumulation, enhances fruit color and smoothness. ⦁ Best Timing: Root sprouting, fruit enlargement, and fruit coloring stages |
 | Vegetables ⦁ Suitable Crops: Tomato, pepper, cucumber, eggplant, leafy greens, etc. ⦁ Function: Strengthens roots, improves stress tolerance, and enhances uniform fruit quality. ⦁ Best Timing: Seedling establishment to fruit setting |
 | Berries ⦁ Suitable Crops: Strawberry, blueberry, raspberry, grape ⦁ Function: Increases sweetness, improves fruit firmness and color, prolongs shelf life. ⦁ Best Timing: Flowering to ripening stage |
 | Field Crops ⦁ Suitable Crops: Cotton, corn, soybean, rice, wheat ⦁ Function: Enhances root development, stress resistance, nutrient use efficiency, and yield stability. ⦁ Best Timing: Vegetative growth to reproductive stage |
Method Of Use
Method | Phenological Period | Dosage | Frequency |
| Drip irrigation | Whole growth period | 0.5-1 L/ha | Every 7-10 days |
| Fertigation | 1-2 L/ha | Every 10-15 days | |
| Foliar spray | Dilute 800-1000 times | Every 10-15 days |
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.
