The present application belongs to the technical field of
fruit tree cultivation, and particularly relates to a continuous
trunk improved
pear tree shape and a cultivation method thereof. Specifically, for the mature
pear tree with open heart-shaped training, the vertical
branch in the middle of the inner cavity of the tree body is selected as the stock after being short-
cut and grafted with
pollination branches to be the central
trunk; the following year, the central
trunk is short-
cut in the middle in winter; in the third year, the central trunk plays the role of
pollination in the flowering period and the inflorescences are removed after flowering; the main branches on the top of the central trunk are pulled to form a "tree on tree" shape; in the fourth year, the central trunk plays the role of
pollination in the flowering period and the inflorescences are removed after flowering or the fruits are left after flowering, and the strong branches are removed; in the fourth winter, the main branches of the central trunk are removed to leave the weak and curved branches, and the side branches are removed to leave the strong and vigorous branches. The method can reduce the
germination rate of the vertical overgrowth branches on the main branches of the original tree by more than 40%, significantly saving the nutrients of the tree body, increasing the average fruit setting rate of the inflorescences, and significantly improving the single
fruit weight of the fruits due to the
pollen collective effect, and increasing the
orchard output value.
