Embodiment Construction

[0015] Below in conjunction with accompanying drawing, the present invention will be further described:

[0016] see figure 1 , figure 2 Test material: new juvenile pear orchard after the main trunk has been dried;

[0017] Select the bamboo pole 2 with a length of 1.5 meters. The bamboo pole 2 is close to the upper part of the main branch 1 branch point. The angle between the bamboo pole and the extension line of the main branch is 30-40°C.

[0018] specifically,

[0019] 1) Bamboo pole oblique insertion: choose a bamboo pole with a length of about 1.5 meters (the diameter of the bamboo pole is more than 2cm), close to the upper part of the branch point, and obliquely insert it into the soil at an angle of 50-60 degrees (25-30cm into the soil), and the bamboo pole crosses the trunk bound with ropes;

[0020] 2) Pull the base angle of the bar: hold the base of the straightened branch with both hands, and twist the branch appropriately to pull the base angle of the branc...

Abstract

The invention discloses a new method for pulling branches of pear trees, which includes the following steps: 1) oblique insertion of bamboo poles: select a bamboo pole with a length of about 1.5 meters, close to the upper part of the branch point, obliquely insert it into the soil at an angle of 50-60°C, and insert the bamboo pole into the soil Bind the intersection with the main trunk with a rope; 2) Pull the base angle of the branch: hold the base of the straightened branch with both hands, and twist the branch appropriately to pull the base angle of the branch; 3) Fix the base angle of the branch: keep the base angle at 45° , fix the lower part of the branch on the bamboo pole in the shape of "8" with a rope, keeping a gap of 2-3cm; 4) Bind the tip of the branch to the bamboo pole in the shape of "8", keeping the tip of the branch and the horizontal direction at 60-80° angle. The patented technology of the invention overcomes the problems of difficult fixing of the base and small tip angles in pulling branches in the past. After pulling the branches, the base angle, waist angle, and tip angles are reasonable, the average growth length of annual branches increases by 52.3%, and the number of back branches decreases. 87.5%.

Description

technical field [0001] The invention belongs to the technical field of fruit trees, and more specifically relates to a method for pruning pear trees. Background technique [0002] Pulling branches is an essential operation technique in pear tree pruning. In the past, pear trees were generally shaped by piling on the ground and pulling branches with ropes. This method can only fix the waist angle in the middle of the branch (the angle between the middle of the branch and the extension line of the trunk), the base angle (the angle between the base of the branch and the extension line of the trunk) cannot be opened, and it is slightly arched, while the apex The tip angle (the angle between the upper part of the branch and the extension line of the main trunk) is relatively large, and some are even horizontal or drooping, and the dominance of the tip cannot be maintained; the growth of the tip is weak after the branch is pulled, causing the branch angle to pull the branch and t...
