How many times should gibberellin acid GA3 be sprayed during the fruit preservation period?
According to experience, it is best to spray 2 times, but not more than 2 times. If you spray too much, there will be more coarse-skinned and large fruits, and it will be too prosperous in summer.
Generally speaking, there are two time points. The first time is after the fruit is slightly mature in spring, and gibberellin can be sprayed once. The second time point is after the fruit has set firmly, and gibberellin can be sprayed once. These two time points are used. After spraying gibberellin at 10 ppm, it can effectively prevent fruit cracking and prevent rough skin.
