The invention relates to a method for culturing tree forms of peach trees. The method comprises the following steps of: selecting
seedling peach trees as root stocks, wherein the
seedling peach trees are good in growing conditions, developed in root systems, free from diseases and
insect pests, 2-3 years old, and over 5 cm in the length of breast diameters; selecting adult peach tree plants which are strong in development and free from
quarantine diseases and
insect pests as scion-seed trees; separately
cutting the smooth
bark of the root stocks to form a horizontal streak and a vertical streak so as to form a T shape; horizontally
cutting the
bark 2-3 mm under a
bud, then 1-1.5 cm above the
bud,
cutting into the root stocks with the knife to upwards push and
cut to a horizontal knife edge under the
bud, taking down a bud piece, unclenching cortex of a notch of the root stock, gently inserting the inverted bud xyloid bud piece which is
cut well into the T-shaped notch, tightly binding up the T-shaped notch and the inverted bud xyloid bud piece with a plastic strip which is 2-3 cm in width, and leaving the bud and a leafstalk outside; after bud
grafting, erecting a rain
awning for blocking rain and directly irradiated sunshine; after buds are germinated, gradually removing the rain
awning; after about 15 days when
grafting is successful, cutting off the root stocks over interfaces; and after entering a growth period, respectively trimming survived branches every month, beginning to trim the branches on upper
layers first, and then trimming the branches downwards.
