What plant growth regulators are used for melon farming?
1. Cultivate strong seedlings
Indole-3-butyric acid (IBA) + Sodium α-naphthyl acetate
Spray seedlings with 10-20 mg/L concentration of indole-3-butyric acid (IBA) + Sodium α-naphthyl acetate or treat seeds with 10mg/L.
Chlormequat Chloride (CCC)
Spraying the leaves of seedlings with 100-500mg/L Chlormequat Chloride (CCC) solution can shorten internodes, thicken leaves and make them green, and resist drought and cold.
Naphthalene acetic acid (NAA)
Soak seeds with 3-6 mg/L Naphthalene acetic acid (NAA) for 12h, and spray 1-2 times during the seedling stage, once every 7 days, to promote strong seedlings, thick leaves, dark green and shiny, and significantly reduce damping-off and leaf blight.
DA-6 (Diethyl aminoethyl hexanoate)
Spraying 10mg/L DA-6 (Diethyl aminoethyl hexanoate) on the leaves of seedlings can make the leaves green and cultivate strong seedlings. (Planting) When irrigating the stump, 100mL of diluted solution per stump can prevent and treat wilt, root rot, etc.
2. Chemical regulation to promote fruit setting
Ethephon
Treat melon flowers with 100mg/L to increase the proportion of female flowers.
Gibberellic Acid GA3
When the young melon grows to the size of an egg, apply 50mg/LGibberellic Acid GA3 to the melon handle once to promote the rapid growth of the young melon. Spraying the stigma or ovary of the female flower with Gibberellic Acid GA3 100mg/L the day before or on the day of flowering can increase the fruit setting rate.
Indole-3-acetic acid (IAA), Sodium α-naphthyl acetate, 6-Benzylaminopurine (6-BA)
If 1%-2% solution of 6-Benzylaminopurine (6-BA) is applied to the ovary or pedicel, the fruit setting rate can be increased by 50% and the yield can be increased by 35%. Spraying flowers with 200-300mg/L aqueous solution of Sodium α-naphthyl acetate can also promote fruit setting. In order to promote fruit setting, while using chemical regulation technology, some agronomic measures and their management must also be coordinated. For example, water should be controlled before flowering and fruit setting, and the relative humidity of the soil should be maintained at 70%-80%, and generally no irrigation is required; the suitable temperature of the greenhouse room is 20℃. If the temperature at the fruit setting point is lower than 18℃, deformed melons are easily formed.
3. Promote the ripening of melons
Ethephon
Spraying the fruit with 500mg/L of Ethephon solution can also accelerate the ripening process, but this type of ripening process does not affect the quality and can be put on the market earlier.
Indole-3-butyric acid (IBA) + Sodium α-naphthyl acetate
Spray seedlings with 10-20 mg/L concentration of indole-3-butyric acid (IBA) + Sodium α-naphthyl acetate or treat seeds with 10mg/L.
