Approaching grafting type double-end bridge grafting method of diseased bergamot pear tree

Abstract

The invention discloses an approaching grafting type double-end bridge grafting method of a diseased bergamot pear tree and belongs to the field of bergamot pear tree bridge grafting.The method includes the steps of firstly, selecting a bridge grafting tree; secondly, preparing the bridge grafting, to be more specific, processing a wound, collecting scions, and selecting the bridge grafting time and position; thirdly, grafting, to be more specific, selecting the scion 10-15cm longer than the wound, covering with a film, cutting off the parts 5-10cm longer than the distance between grafting openings, cutting the ends into horse-ear-shaped cutting faces of 2.5-3cm, and lightly cutting the outer sides to expose the green cortexes; cutting the upper and lower grafting openings into an inverted-T shape and a T shape with the vertical length being not larger than 1 / 3 of the length of the cutting faces and the transverse width being 1.5-2.5 times of width of the cutting faces, and respectively cutting into an inverted Y shape and a Y shape; prying up the cortexes on two sides of the cuts, inserting two ends of the scion into the grafting openings, and allowing the inserted ends to closely attach to the xylem; fourthly, tightly wrapping the grafting openings, and spraying protecting agent; fifthly, removing the films after healing.By the method suitable for being popularized, the survival rate of the diseased bergamot pear tree can reach above 95%, and the fruit setting rate, fruit quality, disease resistance and survival time are increased greatly.

Description

technical field [0001] The invention belongs to the field of disease control of fruit trees, in particular to a sticking type 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 ...

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
