Problems solved by technology

[0004] The technical problem to be solved by the invention: the invention aims at the deficiencies in the prior art, and provides a brand-new method of grape colonization, shaping, management and soil burial for the production of high-quality ice wine in cold-proof areas where grapes are buried in soil, and solves the problem of grape ice wine raw materials before harvesting. A series of problems such as detachment from the parent body, freezing to death and injury of the main vine, and inconsistent grape quality provide high-quality raw materials for the production of real ice wine

Embodiment 1

[0016] Embodiment 1 (adopting single Guyot L-shape mode shaping):

[0017] First of all, the grapes are planted in 0.2-0.25m furrows according to the row spacing of 3.0-3.5m and the plant-to-plant spacing of 0.5-1m. Single Guyot L-shaped shaping with a trunk height of 0.4-0.5m is used to bind horizontal branches (single or double) to the first silk, so that the grape fruiting position is 0.5-0.6m higher than the bottom of the ditch, at the same Height, reduce the incidence of grape diseases. After the grapes are irrigated in winter, use plastic film with a width of 0.3-0.45m or bird-proof nets or other substitutes to tie the grape ears upside down on the grape trellis to maximize the height of the grape ears, and then use mechanical or manual burial until the annual branches In the third section, ensure that the main vine and the base of the annual branch 1 to 3 buds are not frozen. Then, the grape ears are naturally frozen on the tree until harvested (see attached figure ...

Embodiment 2

[0018] Embodiment 2 (adopt double Guyot L shape (or T shape) shaping mode):

[0019] First of all, the grapes are planted in 0.2-0.25m furrows according to the row spacing of 3.0-3.5m and the plant-to-plant spacing of 0.5-1m. Use the double Gouyotte L-shaped (or T-shaped) plastic method with a trunk height of 0.4-0.5m to tie the horizontal branches (single or double) to the first silk, so that the grape fruiting part is higher than the bottom of the ditch 0.5-0.6m, at the same height, to reduce the occurrence of grape diseases. After the grapes are irrigated in winter, use plastic film with a width of 0.3-0.45m or bird-proof nets or other substitutes to tie the grape ears upside down on the grape trellis to maximize the height of the grape ears, and then use mechanical or manual burial until the annual branches In the third section, ensure that the main vine and the base of the annual branch 1 to 3 buds are not frozen. Then, the grape ears are naturally frozen on the tree un...

Abstract

The invention relates to a cultivation method for producing high-quality ice wine raw materials in a cold-proof area buried in soil. The invention belongs to the technical field of fruit tree cultivation, and aims to solve the problem of frostbite of grape branches and tendrils of ice wine produced in my country or the inability to produce high-quality ice wine raw materials according to international standards. Including the following four aspects: (1) Grape planting and shaping methods; (2) Grape burying in soil to prevent cold and fruit ears to freeze naturally; (3) Grape harvesting and secondary burial in soil to protect against cold; (4) In the second spring, cover soil Clear to the bottom of the ditch, and always keep the grape fruiting part 0.5-0.6m higher than the bottom of the ditch to reduce the occurrence of grape diseases, and cultivate according to production needs and according to normal management.

Description

technical field [0001] The invention relates to a method in the technical field of wine grape cultivation, in particular to a cultivation method for providing high-quality raw materials for producing high-quality grape ice wine in buried cold-proof areas. Background technique [0002] Ice wine refers to the wine made from grapes that are naturally frozen on the vine when the temperature drops below -8°C. The definition of ice wine in the "Technical Specifications for Grape Winemaking in China" is: delay the harvesting of grapes, keep the grapes on the branches for a certain period of time when the temperature is below -7°C, freeze them, then harvest and squeeze them. Wine made from grape juice. [0003] The grapes in the international ice wine producing areas are not buried in the soil to protect against the cold. The grapes are naturally frozen, dried, and concentrated without leaving the parent body. When the temperature drops to -8°C, they are harvested and brewed. Conc...
