Problems solved by technology

At present, in spring grape grafting generally adopts hard branch grafting, that is, hard-to-hard grafting. Due to the physiological phenomenon of backflowing water in grape trees, the survival rate of this hard-to-hard grafting method is low; in summer, soft branch grafting is generally used. , that is, soft-to-soft grafting. Although this grafting method improves the survival rate, it is difficult to survive the winter due to the short growth period of grapes in most places in the north and the degree of lignification in that year.

Embodiment 1

[0020] Embodiment one: a kind of method of grape twig grafting hard branch, its grafting method comprises the following steps in solar greenhouse:

[0021] a. Select scion: select the normal annual mature new variety branches and tendrils that grow normally after pruning in winter, and the flower buds are well differentiated, the bud body is full, and there are no branches of diseases and insect pests, thickness 0.6-1cm;

[0022] b. Storage scion: bundle the branches of the new variety selected, and bundle the branches of the new variety selected into a bundle of 20. The dry humidity of the sand is suitable for the sand to be loosened by hand, and label it well. As a scion, it is stored in the sand at -5°C-5°C and refrigerated;

[0023] c. Cultivate rootstock: During the germination period of the first month of the vine in the solar greenhouse, select a strong bud below 40cm, pick the heart when it grows to five leaves and one heart, and use it as a rootstock when it reaches s...

Embodiment 2

[0027] Embodiment two: a kind of method of grape twig grafting hard branch, its grafting method comprises the following steps in the open field:

[0028] a. Select scion: select the normal annual mature new variety branches and tendrils that grow normally after pruning in winter, and the flower buds are well differentiated, the bud body is full, and there are no branches of diseases and insect pests, thickness 0.6-1cm;

[0029] b. Storage of scions: The selected branches of the new variety are bundled into 20 bundles, the dry humidity of the sand is suitable for hand-pressed sand, and it is advisable to loosen the sand, and label it well, and store it as a scion at -5°C-5 ℃ Refrigerate in sand;

[0030] c. Cultivate rootstock: stubble during winter pruning, select and retain more than two rootstocks in May of the next year, pick the heart when they grow to five leaves and one heart, and use them as rootstocks when they reach semi-lignification ten days later;

[0031] d. Scio...

Abstract

The invention relates to a same family and same genus tree species grafting and grape grafting method, in particular to a method for grafting grape softwood to hardwood. The method for grafting the grape softwood to the hardwood is characterized by comprising the following steps of scion selecting, scion storing, stock cultivating, scion grafting, grafting and cultivating. According to the method, the survival rate is high, and the lignification degree is good.

Description

technical field [0001] The invention relates to a method for grafting grapes with tree species of the same family and the same genus, in particular to a method for grafting hard branches with tender branches of grapes. Background technique [0002] With the rapid development of the grape industry, especially the expansion of the area of ​​protected grapes in recent years, the contradiction between the requirements of consumers and the aging of existing grape varieties has become increasingly prominent. At present, in spring grape grafting generally adopts hard branch grafting, that is, hard-to-hard grafting. Due to the physiological phenomenon of backflowing water in grape trees, the survival rate of this hard-to-hard grafting method is low; in summer, soft branch grafting is generally used. , That is, soft-to-soft grafting. Although this grafting method has improved the survival rate, it is difficult to survive the winter due to the short growth period of grapes in most pla...
