How do cultivation techniques adjust the growth rate?

By pruning, bud picking, leaf stripping, girdling, grafting and other cultivation technical measures, regulating plant growth rate has a certain effect on controlling flowering period. The number of days to postpone flowering depends on plant species, harvest and season. Picking a bunch of safflower 1 time or more can delay flowering for more than 20 days, such as flowers for National Day. Picking Lagerstroemia indica 25-30 days in advance, pruning after flowering, and no fruit after 35-50 days.
