Embodiment Construction

[0004] In the early spring, first select pear trees with low quality or degraded varieties as the mother tree, cut off the main pole or main branch at a level 1 meter above the ground as rootstock, and then select high-quality pear tree branches as grafting branches. The grafting branch length is less than 15 cm, with 2-3 spores, cut the bottom of the grafted branch into a wedge shape, use a knife to draw a gap equivalent to the width of the scion on the east side of the flat section edge of the mother tree, and insert the scion firmly into the gap between the brick and wood According to the size of the mother tree, when the diameter of the mother tree is 6 cm from the top, 4 scions are connected in the four directions of southeast, northwest, and the diameter is 4-5 cm. On the mother tree, on the plane cut Connect 3 scions at equal distances, and connect 2 scions symmetrically in the east-west direction of the cross-section of the mother tree below 4 cm, and the air-permeable ...

Abstract

The invention discloses a grafting method of a pear tree. The main stem or main branch of pear tree with deterioration of strains and low quality is cut at the place 1 m away from the ground as a stock A branch of the good-quality pear tree with the length less than 15 cm and 2 to 3 sprouts is used, wherein, the bottom of the branch is cut into wedge shape. A slit with the same width as that of a graft is cut on the pear tree as stock. The graft is stably and tightly inserted into the slit of stock. And then a ventilated plastic film is tightly tightened at the grafting place. 2 to 4 grafts are grafted in the four directions according to the size of the stock. The survival rate of grafts grafted by aforementioned method is over 90% the operation is simple and needs no special trainer; and the method can quickly improve variety and has high economic benefit.

Description

Technical field: [0001] The invention relates to a plant grafting method, more specifically, the invention relates to a method for grafting high-quality pear tree branches to low-quality pear trees. Background technique: [0002] Pear trees can only bloom and bear fruit after 4 years of planting. The cycle is long, which affects economic income. The buds on good-quality pear trees are grafted to branches of low-quality pear trees, and branches of high-quality pears can grow. The pears that can bear the original quality will be high-quality pears on the new branches. Invention content: [0003] The purpose of this invention is to transform low-quality pear trees into high-quality pear trees, and to provide a method for grafting high-quality pear tree branches to low-quality pear trees. This method is simple and quick to improve pear varieties. detailed description: [0004] In the early spring, first select pear trees with low quality or degraded varieties as the mother ...
