The invention discloses a full-
branch grafting method for a
fruit tree and belongs to the technical field of
agriculture. The method comprises the following steps: (1), scion selection and storage, wherein the scions are collected and are subjected to
moisture-holding storage at a low temperature after being sealed by
wax; (2), old
tree shaping, wherein the tree is shaped at the height of 2.5-3.5 m, unwanted side branches are removed, and 3-5 important main branches are reserved; (3),
punching, wherein
punching is performed at the smooth part of a selected big
tree trunk or a principle
branch side surface with the scion interval of 19-21 cm; (4),
grafting, wherein the well
cut scion is inserted into a stock notch by the right hand to reach an extent that the lower end of the scion is propped against the bottom of the stock notch, and the scion and the stock are in alignment and
close contact on two surfaces; (5), binding up, wherein a layer of mulching film plastic cloth is bound up at the scion part, and two
layers bound up at the non-scion part; and processes such as
bud picking, water fertilizing, wind protection, disbranching, spraying and
insect prevention are carried out after
grafting. According to the invention, the grafting technology has the
advantage that the fruit bearing area of the old tree is increased, and also has the advantages of
high survival rate, thriving tree vigour, high yield, quickness in shaping, simplicity in maintenance and the like.
