Application of plant growth regulators in radish farming

(1) Gibberellic Acid GA3:
For radishes that have not undergone low-temperature vernalization but want to bloom, 20-50 mg/L Gibberellic Acid GA3 solution can be dripped onto the growth point before the radish has overwintered, so that it can bolt and bloom without low-temperature vernalization.

(2) 2,4-D:
15-20 days before harvest, spraying 30-80 mg/L 2,4-D solution in the field, or spraying leafless and topped radishes before storage, can significantly inhibit germination and rooting, prevent hollowing, improve radish quality, and have a fresh-keeping effect.

(3) 6-Benzylaminopurine (6-BA):
Soak radish seeds in 1 mg/L 6-Benzylaminopurine (6-BA) solution for 24 hours and then sow them. After 30 days, the fresh weight of radishes can be observed to increase.
Spraying 4mg/L 6-Benzylaminopurine (6-BA) solution on the leaves of radish seedlings has the same effect. At the 4-5 leaf stage, spraying 10 mg/L solution on the leaves, 40 liters of solution per mu, can improve the quality of radish.

(4) Naphthalene acetic acid (NAA):
First spray the solution of Naphthalene acetic acid (NAA) on paper strips or dry soil, then evenly spread the cloth strips or dry soil into the storage container or cellar and put it together with the radish. The dosage is 1 gram per 35-40 kg of radish. 4-5 days before the radish is harvested, 1000-5000 mg/L Naphthylacetic acid sodium salt solution can be used to spray the leaves of field radish to prevent sprouting during storage.

(5)Maleic hydrazide: 
For root vegetables such as radish, spray the leaves with 2500-5000 mg/L Maleic hydrazide solution 4-14 days before harvest, 50 liters per mu, which can reduce the consumption of water and nutrients during storage, inhibit germination and hollowing, and extend the storage period and supply period by up to 3 months.

(6)Triacontanol: 
During the period of fleshy expansion of radish, spray 0.5 mg/L Triacontanol solution once every 8-10 days, 50 liters per mu, and spray continuously 2-3 times, which can promote plant growth and fleshy root hypertrophy, making the quality tender.

(7)Paclobutrazol (Paclo): 
During the period of fleshy root formation, spray 100-150 mg/L Paclobutrazol (Paclo) solution on the leaves, 30-40 liters per mu, which can control the growth of the aboveground part and promote fleshy root hypertrophy. 

(8)Chlormequat Chloride (CCC), Daminozide: 
Spray radish with 4000-8000 mg/L Chlormequat Chloride (CCC) or Daminozide solution for 2-4 times, which can significantly inhibit bolting and flowering and avoid the harm of low temperature.
