The growth of the roots, stems, leaves and other vegetative organs of green flowering plants is called vegetative growth. When green plants grow vegetatively to a certain period, they begin to form flower buds, which will then bloom, bear fruit, and form seeds. The growth of reproductive organs such as flowers, fruits, and seeds of plants is called reproductive growth. Certain conditions are required for plants to transition from vegetative growth to a stage dominated by reproductive growth. First of all, it depends on the vegetative organs of plants to produce and accumulate a certain amount of organic matter. Secondly, different plants also require different external conditions. If the vegetative growth of the plant is too strong, it will affect the reproductive growth, so reshaping the fruit tree is to adjust the two types of growth, which will help concentrate the organic matter produced by the fruit tree to the strong branches, so as to improve the quality of the fruit produced.
