Root Growth & Fruit EnlargementXuelong XUELONG
Root Growth · Sweeter Fruit · Faster Enlargement
所属分类：Humic/Fulvic Acid & Seaweed
规格：2 kg × 10 bags
适用作物：Fruit trees, vegetables
技术指标：Humic acid water-soluble fertilizer, humic acid ≥3.0%, N+P₂O₅+K₂O ≥20%, seaweed extract ≥40 ppm
作用原理
Humic acid chelates high-potassium to form sustained-release chelates, reducing salt damage risk and promoting potassium transport toward fruit through phloem loading. Adequate potassium supply activates sucrose synthase activity, accelerating translocation of photosynthates to fruit (sink organs), increasing soluble solids content (Brix) by 1–3°. Humic acid simultaneously stimulates root vitality and increases fibrous root density, enhancing water and nutrient absorption efficiency.
产品特点
- ✓Synergistic action of humic acid and high potassium: promotes rapid fruit enlargement, significantly improves colouring and sugar accumulation — brings fruit to market 7–10 days earlier
- ✓Humic acid stimulates extensive fibrous root generation, expanding root absorption area; plants receive more complete nutrition for a dual effect of stronger seedlings and better root development
- ✓Balances vegetative and reproductive growth: precise potassium supply after flower bud differentiation improves fruit set rate and reduces fruit cracking, hard fruit, and deformity
- ✓100% water-soluble for drip irrigation or fertigation — small dosage, fast results; best used intensively from fruit enlargement through to harvest
使用方法
- •Drip irrigation: dilute 600–800× and drip with irrigation water, 2–4 kg/mu per application
- •Fertigation: dilute 500–600× and apply with irrigation water
- •Key application window: fruit enlargement and colour-break stages; apply every 7–10 days for 2–3 consecutive applications for best results
