What‘s plant growth regulators are needed for celery cultivation?
During the celery planting process, the use of plant regulators can effectively promote its growth and increase yield. The following are some commonly used plant regulators and their use methods:

Gibberellic Acid GA3:
2-3 weeks before the celery is harvested, spray Gibberellic Acid GA3 solution with a concentration of 20-50 mg/L 1-2 times, and spray 40-50 liters of solution per acre each time.
This method can enhance the cold resistance of celery, make the leaf color lighter, grow faster, enlarge the stems and leaves, lengthen the petioles of the edible part, reduce cellulose, and increase the yield by about 20%, so as to achieve the purpose of early harvest. Note that
the concentration of Gibberellic Acid GA3 should not be too high when spraying, so as not to make the plants too slender. Within 1-2 days after spraying Gibberellic Acid GA3, fertilizer should be added and harvested in time to prevent plant aging.
Triacontanol:
After celery is planted, use 0.5 mg/L Triacontanol solution, spray 50 liters per mu, spray once every 10 days or so, spray 3-4 times in total, and stop spraying half a month before harvest. This method can promote plant growth, increase yield, and improve quality. Application of triacontanol 15-20 days before harvest is the key to increase yield; When applying Triacontanol in winter, insulation measures should be taken to achieve the best yield-increasing effect.
Brassinolide (BRs):
During the celery heart-establishing period, spraying Brassinolide (BRs) 0.01 mg/L solution on the leaves can increase the height of celery plants by 5%-12%, increase weight by 8%-15%, increase chlorophyll content by 0.55%-2.81%, and make the leaves dark green and shiny. If you spray the leaves once again 10 days before harvest, you can improve the physiological activity of celery and enhance its resistance to stress, making it more resistant to storage and transportation.
Chlormequat Chloride (CCC):
Spray the growing point with 4000~8000 mg/L Chlormequat Chloride (CCC) solution to inhibit bolting and flowering and improve quality.
Paclobutrazol (Paclo):
Starting from 4~5 true leaves, spray the leaves with 200~500 mg/kg solution, once every 10~15 days. This method can promote the growth of roots, stems, and leaves, improve photosynthesis, resist diseases, and increase yield by 25%~40%1.
When using these plant regulators, you should pay attention to the recommended dosage and usage instructions in the instructions to avoid excessive use that may cause abnormal plant growth or phytotoxicity. At the same time, attention should be paid to protecting the environment, using pesticides and regulators rationally, and ensuring the safety and reliability of agricultural products.
