Technical requirements for use
Technical requirements for use:
1.Gibberellin is mixed with urea and other fertilizers.
1) Before flowering, 1g/kg urea and 1g/kg phosphoric acid were added to 20mg/l GA3 treatment solution for mixed use to increase seedless fruit formation, reduce fruit falling rate, and increase weight and yield
2) Citrus and lemon seedlings were sprayed with 100-200mg/l ga3 mixed with 0.5% urea to promote seedling growth
3) Before flowering, the whole plant was sprayed with the mixture of gibberellic acid and urea (5-10mg/l +0.5%), which could improve the yield of navel oranges
2. Citrus: Spray about 2/3 of the flowers and 10 days after the flowers fall, as well as in the fruit swelling stage.
3.Washington navel orange:The application of gibberellin 250ml/L and benzyl adenine 200mg/l in fruit coating can improve the fruit setting rate and significantly increase the yield.
