Perforation type double-end bridge joint method for diseased bergamot pear trees

Abstract

The invention discloses a perforation type double-end bridge joint method for diseased bergamot pear trees, and belongs to the field of bridge joint of bergamot pear trees. The method includes the steps of 1, selecting bridge joint trees; 2, making bridge joint preparation, wherein wounds are treated, scions are collected, and bridge joint time and bridge joint positions are selected; 3, carrying out grafting operation, wherein the scions 10-15 cm longer than the wounds are selected and covered with films in a winding mode, parts 5-10 cm longer than joint intervals are cut away, ends are cut in to a wedge shape, cut faces are made smooth and flat, wedge-shaped joints are chiseled out at grafting positions, the wedge-shaped joints reach deep to xylem by 0.5-1 cm, the width of the wedge-shaped joints is matched with that of the scions, edges are cut to be neat, the scions are inserted into the joints at the corner of 15-30 degrees and fixed in an arch shape without displacement or dislocation, the joints are tightly wrapped till airtightness is achieved, and moisture is ensured; 4, spraying a protective agent, and preventing the scions form being touched; 5, removing the films after healing. The perforation type double-end bridge joint technology for the bergamot pear trees is created, so that the survival rate of the diseased trees reaches 95%, the fruit setting rate is significantly increased, the fruit quality and the disease resistance are significantly improved, and the survival time is significantly prolonged; the perforation type double-end bridge joint technology for the bergamot pear trees is suitable for popularization.

Description

technical field [0001] The invention belongs to the field of disease control of fruit trees, in particular to a perforated double-head bridging method for a diseased fragrant pear tree of Korla fragrant pear trees. Background technique [0002] Since 2007, the Korla fragrant pear industry in Xinjiang has developed rapidly. In recent years, the average annual export is 20,000 to 30,000 tons, with an average annual foreign exchange earning of about 30 million US dollars. The products have been exported to more than 20 countries including the United States, Canada, Australia, and Southeast Asia. and regions, Korla pear has been well-known at home and abroad. [0003] However, there have always been problems of frequent natural disasters in the development of Korla fragrant pear industry. Among them, low temperature freezing damage often poses a fatal threat to the production of Korla fragrant pears. From the winter of 2002 to the spring of 2003, the fragrant pears in Korla Cit...

AI Technical Summary

Problems solved by technology

[0009] 1. The existing bridging technology for fragrant pear trees is mostly applied to apples and ordinary fragrant pear trees. There is a lack of bridging technical data for Korla fragrant pears. In the production of fragrant pears, fruit farmers do not have suitable technical parameters when using bridging technology, resulting in Non-standard operation and unscientific parameters lead to low survival rate of bridging

[0010] 2. When the existing fragrant pear tree bridging technology is applied to the fragrant pear tree, it needs to plant Duli pear seedlings, which takes at least 1 to 2 years, the workload is heavy, and the operation process is too complicated

[0011] 3. When bridging is carried out, the natural tension of the scion affects the joint healing and survival. The existing pear tree bridging technology is to fix the joint with small nails, and then use plastic straps to tie it tightly. It is difficult to operate with small nails. The nail has damage to the scion, which affects the healing effect of the interface

[0012] In summary, the development of the fragrant pear industry urgently needs a set of bridging methods suitable for fragrant pear trees, which are used to solve the above-mentioned technical problems existing in the existing bridges, and to solve the problem of heavy losses caused by freezing damage and rot in fragrant pear trees
