High-Potassium NPK Compound Fertilizers are designed to meet potassium demands during late growth stages of crops (fruit expansion/sugar accumulation/stress resistance enhancement).

Quality Enhancement: Activates starch/sugar transport enzymes, significantly increasing:
Fruit sugar content (e.g., grapes: +1.5–2°Brix), Vitamin C levels, Color development.

Stress Resistance Reinforcement: Maintains cellular osmotic pressure, enhancing resistance to: drought, cold stress, disease.

Fruit Enlargement & Senescence Delay: Promotes translocation of photosynthetic products to fruits, reducing late-stage fruit drop.

Restricted Scenarios:

Chloride-sensitive crops (e.g., tobacco, grapes): Avoid chloride-containing potassium fertilizers (e.g., KCl).

Saline-alkali soils: Avoid sulfate-based potassium fertilizers (aggravates salinization).

Prohibited Mixtures: Calcium magnesium phosphate, Ammonium bicarbonate (triggers ammonia release reaction).

Application Interval: Allow ≥3 days between calcium fertilizer applications (prevents CaSO₄ precipitation and drip emitter clogging).

Critical Warning:

Continuously applying high-potassium fertilizers requires monitoring soil EC (electrical conductivity) to prevent salinization: STOP USE if sandy soil EC >1.5 mS/cm
