From flowering period to fruit enlargement period: Spraying 0.1mg/L (4kg of water per grain) on the leaves can significantly increase the weight of the fruit, enhance the plant's ability to resist low temperatures, and reduce the damage of diseases.

       When the fruit enters the ripening stage: Spray the fruit with a concentration of 10mg/L (25 capsules mixed with 1kg of water), repeat once after 6 days, and spray a total of 3 times. 5 days after the second treatment, there is a color changing and ripening promoting effect, and brassinolide has a promoting effect on endogenous ethylene production in fruits.
