Gibberellic acid is a broad-spectrum plant growth regulator, which can promote the growth and development of crops, make them mature earlier, increase yield and improve quality. It can quickly break the dormancy of seeds, tubers, bulbs and other organs and promote germination; Reduce bud, flower, bell and fruit shedding, improve fruit bearing rate or form seedless fruit. Can also cause certain two-year-old plants to bloom that year,

Gibberellic acid usage:
1. Promote the formation of fruit setting or seedless fruit. Spray cucumber with 50-100mgg solution once during flowering to promote fruit setting and increase yield. 7-10 days after flowering, the rose fragrant grapes were sprayed with 200-500mg/kg of liquid once to promote the formation of stone free fruit.
2. Promote nutritional growth of celery 2 weeks before harvest, spray the leaves with 50-100mg/kg liquid medicine once; Spray the leaves 1-2 times 3 weeks before harvest to enlarge the stems and leaves.
3. Soak tubers with 0.5-1mgkg solution for 30min before sowing potatoes to break dormancy and promote germination; Soaking the seeds with 1mg/kg liquid medicine before sowing can promote germination.
4. Anti-aging and fresh-keeping effect Garlic moss with 50mgkg medicinal solution 10-30min, citrus green fruit period with 5-15mg/kg medicinal solution spray fruit once, banana after harvesting with 10mgkg medicinal solution soak fruit, cucumber, watermelon before harvesting with 10-50mg/kg medicinal solution spray melon, can play a fresh-keeping effect.

5. Adjust the flowering chrysanthemum vernalization stage with 1000mgkg of liquid spray leaves, cypien period with 1-5mg/kg of liquid spray flowers can promote flowering.
6. To improve the seed setting rate of hybrid rice seed production, it is generally started at 15% heading of the mother, and treated with 25-55mg/kg liquid medicine for 1-3 times at the end of 25% heading. Use low concentration first, then high concentration
Gibberellic acid is less water-soluble, dissolve with a small amount of alcohol or liquor before use, and then dilute with water to the required concentration.
