Calcium-Magnesium-Boron Plus (CaMgB)
Top Calcium ChoiceThe Ultimate Calcium Supplement — CaMgB Medium Trace Fertilizer
The Ultimate Calcium Supplement
所属分类：Secondary & Trace Elements
规格：5 kg × 4 bags
适用作物：Vegetables, fruit trees

作用原理
The sugar alcohol carrier enables Ca²⁺ to overcome the limitation of 'xylem-only' transport, allowing bidirectional phloem transport directly to fruit and growing points — calcium supplementation efficiency is 40–60% higher than conventional calcium fertilizers. Magnesium is the core element for chlorophyll synthesis (the Mg²⁺ at the centre of the chlorophyll molecule). Boron participates in callose synthesis required for pollen tube elongation. The three-element synergy improves fruit set rate.
产品特点
- ✓Rich in small-molecule sugar alcohol calcium transported via both xylem and phloem pathways — reaches fruit and young leaves directly for precise, efficient calcium supplementation, solving the transport limitation of ordinary calcium fertilizers
- ✓Three-element synergy of calcium, magnesium, and boron: mutual promotion of absorption effectively prevents bitter pit, king fruit, blossom-end rot, and other calcium-deficiency physiological disorders
- ✓Increases flower and fruit set rate, reduces flower and fruit drop — especially effective when applied at flowering and young fruit stages
- ✓Simultaneously supplements magnesium and sulphur, enhancing chlorophyll synthesis capacity and amino acid content, improving the taste and storage quality of fruit and vegetables
使用方法
- •Fertigation / drip irrigation: 5 kg/mu, every 10–15 days; focus applications from fruit set to fruit enlargement stage
- •Foliar spray: dilute 500–800×, apply at fruit set and during fruit enlargement stage
- •Recommended to spray before 10:00 AM or after 4:00 PM; avoid high-temperature periods
按作物施用指南
| 适用作物 | 施用方式 | 用量/浓度 | 施用时期 |
|---|---|---|---|
| Tomato / pepper (fruit-set calcium) | Fertigation / drip | 5 kg/mu | Starting at fruit set after petal-fall, every 10–15 days |
| Apple / pear (pre-bag) | Foliar spray | Dilute 500–800× | Petal-fall to pre-bagging, every 7–10 days |
| Watermelon / melon | Fertigation | 5 kg/mu | Fruit-set to enlargement stage, every 10 days |
| Strawberry | Drip irrigation | 3–5 kg/mu | Flowering stage to young fruit stage, every 7 days |
注意事项
- !Concentrate calcium supplementation before flowering or within 15 days after fruit set to effectively prevent reduced large-fruit rates
- !Complete 2–3 foliar calcium sprays before bagging; do not mix in the same tank as monopotassium phosphate
