Gobi grape field hard branch grafting method

Abstract

The invention relates to a gobi grape field hard branch grafting method which comprises the following steps that (1) a place where terrain is flat and the diameters of sand stones are smaller than 5cm in gobi is selected for building of a vineyard; (2) the vineyard is built, namely first, ditching is carried out in the vineyard, then surface soil is padded, cow and sheep manure is mixed, subsoil or sandy soil covers the manure, finally flattening is carried out to form a shallow ditch; second, a cement frame column row is inserted on one side of the shallow ditch, 3-4 iron wires are used for being pulled on the cement frame columns; third, grape stock seedlings are processed and then are fixedly planted in a fix-planting hole; fourth, stock management is carried out according to a conventional method, stocks which need grafting are obtained; (3) grafting time is selected; (4) pinching processing is carried out on the stocks which need grafting; (5) branches full with annual bud eyes are used as scions and are stored for a winter, then scion nursery stocks are obtained; (6) the scions are activated, then the scions which need grafting are obtained; (7) grafting is carried out; (8) field management is carried out; (9) planting management is carried out according to the conventional method. According to the method, grafting time can be prolonged, and under the situation that the anti-freezing stocks are used, the phenomena of root freezing of grape planting are avoided.

Description

technical field [0001] The invention relates to the technical field of agricultural cultivation, in particular to a method for grafting hard branches of Gobi grapes in the field. Background technique [0002] Grape grafting is the current grape cultivation method in most countries in the world. Grape rootstocks are anti-virus, drought-resistant, cold-resistant and disease-resistant, etc. Grafting the excellent nutrient system of detoxified wine grapes on excellent virus-free grape rootstocks can expand the planting area, increase yield, improve quality, reduce pests and diseases, and reduce production costs. This has become an important measure for the development and cultivation of grapes in the world, and it is the content of the modernization of fruit trees, which is of great significance. Our country is not yet popular, but we have realized that grape grafting has many benefits. [0003] Commonly used grape grafting includes indoor hard branch grafting, shed hard branc...

Problems solved by technology

[0004] Although there are many grafting methods for grapes, the green branch grafting technology in the field is relatively mature and widely used. However, in the Gobi area with a short frost-free period, the growth period after grafting is less than three months. The new shoots of the rootstock are not semi-lignified, so it cannot be carried out. If it is to be carried out, the rootstock and scion can only be cultivated in the greenhouse in advance, otherwise it cannot be realized, which will increase the cost

[0005] In the dry, windy and sandy land in the Gobi area, although the soil is buried, the sand and stones have poor thermal insulation. The applicant measured the grape buried in the Gobi area in 2010 and found that the underground temperature in some areas was lower than the tolerance temperature of the grape root system, resulting in Underground grape roots are frozen
