‌ Root Growth‌

Enhances root development, improving ‌water and nutrient absorption efficiency‌.

‌Growth Regulation‌

Effectively controls ‌apical dominance‌, preventing excessive vegetative growth.

In citrus and cherry trees: ‌Thickens leaves‌, accelerates spring shoot maturation, suppresses summer shoot growth, and ‌ensures flower/fruit retention‌.

‌ Flower Quality Enhancement‌

Promotes ‌flower bud differentiation‌, yielding fuller, healthier blooms and ‌higher fruit set and quality‌.

‌Accelerated Shoot Maturation & Fruit Greening‌

Speeds up new shoot maturation and enhances greening of young fruits.

‌Rapid Nutrient Supplement‌

 Contains ‌high-concentration phosphorus and potassium (675 g/L)‌, quickly replenishing essential nutrients and trace elements.




‌Key Features (Potassium Phosphite Advantages)‌

‌1. Rapid Absorption & Translocation‌
► Absorbed via ‌
leaves, roots, xylem,and phloem‌ at ‌5× the speed of phosphate-based phosphorus‌.
►
Ensures timely nutrient supply during peak flowering/fruiting, outperforming monopotassium phosphate ‌by 3×‌.

‌2. Dual Action: Disease Prevention & Nutrition‌
► ‌
+3 Phosphorus‌ acts as both fertilizer and ‌systemic fungicide‌:

· Activates plant immune responses, inhibits fungal spore formation, and disrupts pathogen cell walls.

‌3. Bidirectional Translocation & Stress Resistance‌
►
Bidirectional transport triggers ‌polyphenol synthesis‌ and ‌reactive oxygen production‌, boosting defense enzyme activity.
►
Prevents internal infections and enhances ‌disease/drought/salinity resistance‌.

‌4. Soil Improvement & Nutrient Release‌
►
Releases fixed ‌calcium, zinc, and iron‌ in soil, improving rhizosphere conditions and soil structure.
► Minimizes soil fixation, maximizing micronutrient availability.

‌5. High Safety & Compatibility‌
►
Compatible with ‌copper-based formulations‌, most pesticides, and fertilizers (excluding strong alkaline products).
►
Safe for use during ‌spring shoots and young fruit stages‌ with ‌zero phytotoxicity risk‌.

 

Application Guidelines‌

‌1. Foliar Spray (Recommended)‌
► ‌
Dilution Ratio‌: 1:1000 (e.g., 1 mL per 1 L water).
►
‌Best Practices‌:

· Apply at windless dusk, ensuring full leaf coverage (both surfaces).

· Use ‌2-3 times per growth cycle‌.

‌2. Drip Irrigation/Root Drenching‌
► ‌
Dosage‌: 300-500 mL/acre per application, combined with other fertilizers.
► ‌
Frequency‌: ‌2-3 times per growth cycle‌.
