For some varieties with large fruit size, high pedestal height, and large ear, in order to ensure that there is enough space for normal fruit swell, it is necessary to appropriately lengthen the inflorescence by using growth regulators. The elongated inflorescence uses a gibberellin solution at a concentration of 3 to 5 mg/l and a treatment time of 7 to 10 days before flowering, that is, when 10 to 11 leaves are on the resulting shoot. Inflorescence stretching agent not only has the function of elongated inflorescence, but also has a strong effect of sparse flowering. Therefore, it is generally not necessary to extend the inflorescence of the giant peaks that are heavy in flowering to prevent flowering and fruit falling. At the same time, in the hot and humid environment and facilities cultivation, the inflorescence can generally stretch naturally, and it is not necessary to carry out drug treatment to elongate the inflorescence.
