Embodiment 1

[0026] The green branch high position grafting method of grape vine comprises the following steps:

[0027] a. The choice of rootstock: select the century-old vine longan grape as the rootstock variety for grafting in Xingyuan Village, Huaizhuo production area;

[0028] b. Cultivation of rootstocks: choose healthy longan vines. In mid-September in autumn, according to the growth of the vines, leave 60cm for winter pruning. On June 20 of the second year, choose high semi-lignified annual greens 80cm from the ground. Branches are used as rootstocks for grafting branches;

[0029] c. Collection of scions: select high-quality non-toxic Cabernet Sauvignon vineyards nearby, and collect scions for grafting. Select semi-lignified green shoots for scions. The thickness of scion branches is equivalent to that of rootstock to be grafted. Cut a section 4cm long Remove the leaves and keep only the 0.8cm long petiole, wrap it with a wet towel, and quickly transport it to the grafting site;...

Embodiment 2

[0045] The green branch high position grafting method of grape vine comprises the following steps:

[0046] a. Selection of rootstock: select the 30-year-old vine longan grape in Xingyuan Village, Huaizhuo production area as the rootstock variety for grafting;

[0047]b. Cultivation of rootstocks: Choose healthy longan vines. At the end of September in autumn, according to the growth of the vines, leave 65cm for winter pruning. On July 1st of the next year, choose high semi-lignified annual green branches 90cm from the ground Grafting branches as rootstock;

[0048] c. Collection of scions: select high-quality non-toxic Cabernet Sauvignon vineyard nearby, collect scions for grafting, select semi-lignified green shoots for scions, the thickness of scion branches is equivalent to the thickness of rootstock branches to be grafted, and cut a section of 4.5cm For the long shoots, remove the leaves and keep only 1cm long petioles, wrap them in a wet towel, and quickly transport the...

Embodiment 3

[0063] The green branch high position grafting method of grape vine comprises the following steps:

[0064] a. Selection of rootstock: select the 30-year-old vine longan grape in Xingyuan Village, Huaizhuo production area as the rootstock variety for grafting;

[0065] b. Cultivation of rootstocks: Choose healthy longan vines. In early October in autumn, according to the growth of the vines, leave 70cm for winter pruning. On July 8th of the next year, choose high semi-lignified annual green branches 100cm from the ground Grafting branches as rootstock;

[0066] c. Collection of scions: select high-quality non-toxic Cabernet Sauvignon vineyard nearby, collect scions for grafting, select semi-lignified green shoots for scions, the thickness of scion branches is equivalent to the thickness of rootstock branches to be grafted, and cut a section 5cm long Remove the leaves of the new shoots and keep only the 1.2cm long petiole, wrap it with a wet towel, and quickly transport it to ...

Abstract

The invention relates to the technical field of plant grafting, and particularly discloses a green branch high-position grafting method for grape trees. The grafting method comprises the following steps: a, selecting longan grape trees as a grafted stock variety; b, cultivating stocks; c, selecting semi-lignified green branch shoots of cabernet sauvignon trees as scion branches; and d, grafting. The grafted variety has the characteristics of excellent disease resistance, cold resistance, drought resistance, waterlogging resistance, acid resistance, salt and alkali resistance and high yield; inaddition, the longan grape stocks can provide sufficient nutrients for cabernet sauvignon scions, high-quality grapes can grow, and the grapes taste sweet; and meanwhile, the grape trees have the conditions of fresh eating and brewing of high-quality wine, and have important significance for planting and development of fresh eating grapes and brewing grapes.

Description

technical field [0001] The invention relates to the technical field of plant grafting, in particular to a method for high-position grafting of green branches of vines. Background technique [0002] Grapes have a long history of growing in my country, but the wine industry has not been taken seriously, especially the output of wine grape varieties can not meet the current market demand for wine production, which limits the rapid development of my country's wine industry. At present, most of the high-quality wine grape varieties in my country are mostly European species, which do not grow well in Asia, especially in the arid North China, which is easily affected by drought, cold environment and pests and diseases, which seriously affects its yield and the taste of the brewed wine. . [0003] In order to improve the yield of wine grapes and the ability to resist diseases and insect pests, grape grafting technology is often used at present, and grape varieties with well-develope...
