Problems solved by technology

However, the traditional high-splicing head-changing technology is not effective on pear trees over 5 years old, mainly reflected in the low survival rate of main vine branches, poor aging and renewal ability, poor disease resistance, and weak growth, resulting in poor ability to grow new branches. Outward shift of result site

Embodiment 1

[0037]Step (1) Cultivate rootstock: Saw the trunk of the pear tree until it is 130-140 cm above the ground, and cut an upper incision downward at the middle position of the top surface of the trunk of the pear tree, so as to form the rootstock, and the upper incision has A vertical section and an inclined section, the depth of the upper cut is 5cm, and the inclined section has three lower cuts along the direction perpendicular to the inclined section, the depth of the lower cut is 1cm. Process an inclined circular hole downwards at the top of the main trunk of the pear tree, the end of the circular hole communicates with the lower incision, and process a cylindrical plug consistent with the diameter of the circular hole, the cylindrical plug plugged into the round hole.

[0038] Step (2) scion processing:

[0039] Select a mature green branch that is born in the current year as the scion, the end of the scion is cut into a pointed end, and the pointed end has a vertical bevel...

Abstract

The invention discloses a planting method for pear trees. The method comprises the following steps: (1) cultivating a rootstock: cutting an upper cut downwards at the top surface of a pear tree main trunk, and cutting at least two lower cuts along the direction perpendicular to a tilted cut surface in the tilted cut surface; and processing a tilted circular hole downwards at the top surface of thepear tree main trunk, enabling the tail end of the circular hole to communicate with the lower cuts, processing a cylindrical stopper with the same diameter as that of the circular hole, and pluggingthe cylindrical stopper into the circular hole; step (2) performing scioning treatment: cutting the tail ends of scions into sharp ends, and connecting at least two sharp ends along the direction perpendicular to an inclined cut surface with the inclined cut surface; step (3) performing grafting: inserting the tail end of one scion into the upper cut; and step (4) performing binding: opening thecylindrical stopper every 3-5 days, so as to open the circular hole for 30 minutes; and spraying water to the scions every 2-3 days, wherein water is sprayed until the outer surfaces of the scions arewet. According to the method provided by the invention, the survival rate of grafting is higher, and the growth vigour of grafted seedlings is better.

Description

technical field [0001] The invention relates to a method for planting pear trees. Background technique [0002] Pear tree high grafting is the shortest way to update old varieties. At present, the traditional method of high grafting for perennial trees is to select 6 to 10 strong main vines from the main vines of the strong tree body, and from the Grafting in different directions generally enters the initial fruit stage in the second year after grafting, and enters the full fruit stage in the third year. The loss of income for fruit farmers is small, and it is the most suitable grafting method for variety replacement. However, the traditional high-splicing head-changing technology is not effective on pear trees over 5 years old, mainly reflected in the low survival rate of main vine branches, poor aging and renewal ability, poor disease resistance, and weak growth, resulting in poor ability to grow new branches. As a result, the site moves outward. Contents of the inventi...
