Nano-chelated brassinolide foliar fertilizer resists cold and waterlogging eliminates pesticide damage and repairs cell activity

1. Promote growth and development
- Root system: induce lateral root formation and improve root vitality (experiments show that root length increases by 20%-30%).
- Stems and leaves: promote cell elongation (by activating the EXPANSIN gene) and division, increase leaf area and photosynthetic efficiency.
- Flowers and fruits: improve pollen vitality, promote pollination and fruit setting (such as strawberry fruit setting rate increased by 15%-25%).

2. Enhance stress resistance
- Abiotic stress:
- Drought resistance: induce proline accumulation and reduce water loss (yield loss reduced by 10%-20% under drought conditions).
- Salt-alkali resistance: regulate Na⁺/K⁺ balance and alleviate ion toxicity.
- Low temperature resistance: maintain membrane stability and reduce frost damage (such as cucumber seedling survival rate increased by 30%).
- Biological stress: activate PR protein (pathogenesis-related protein) to enhance resistance to fungi and viruses.

3. Increase yield and improve quality
- Yield: Promote the transport of photosynthetic products to the fruit, increase thousand-grain weight (such as 8%-15% increase in rice yield).
- Quality: Increase sugar content (such as 5%-12% increase in sugar content in grapes), vitamin C content, improve fruit shape and color.

4. Delay aging
Inhibit ethylene synthesis and chlorophyll degradation, and extend the functional period of leaves (such as 3-5 days extension of wheat filling period).
