Problems solved by technology

One of the key issues is the overwintering of the ice grape vines. It is necessary to provide grapes that meet international standards for the production of ice wine, and to ensure that the vines can survive the winter normally so that the trees will not be frozen to death and ensure that the grapes are not frozen to death. The sustainable development of the orchard, at present, there is no standardized planting method that can handle ice grape cultivation overwintering technology on a large scale.

Embodiment 1

[0016] Embodiment 1, a kind of ice grape culture overwintering technology, its method is:

[0017] (1) Covering between rows and burying after harvest to prevent cold.

[0018] Before the soil starts to freeze in winter, cover the place between the rows of grapes that needs to take cold-proof soil with mulch such as corn stalks or grass curtains. When the temperature reaches -8°C, the grapes are harvested and immediately trimmed and removed from the shelf. After removal from the shelves, cover the vines between the rows with the vines after removal from the shelves, and then bury them in the soil to prevent the cold;

[0019] (2), multi-vine replacement, buried cold protection method:

[0020] For the newly planted ice grape seedlings, when the grape seedlings have survived slowly, leave 4 leaves to pick the heart. After the new shoots germinate, select 3 strong new shoots to be cultivated as the main vines, and the redundant new shoots are erased to ensure 3 main vines. The...

Abstract

The invention relates to a grape planting method, in particular to ice grape culture overwintering technology. Methods of the ice grape culture overwintering technology include: covering between lines and soil covering cold-proof method after harvest; and multiple vane replacing and soil covering cold-proof method. By adopting management technology to guarantee that a fruiting main vane, a preparing main vane and a cultivating main vane are maintained on a frame surface all the time, namely multiple vane circulation replacement. Thus, stable ice grape output can be guaranteed no matter how winter climate changes, the problem between ice grape production and tree overwintering is solved, persistence of the ice grape production is guaranteed, ice grapes with high quality can be produced, and production capacity of large-scale ice grape planting can be achieved.

Description

technical field [0001] The invention relates to a method for planting grapes, more precisely a technique for overwintering ice grape cultivation. Background technique [0002] Ice grape is a kind of rare and precious grape variety. Different varieties have different aromas. Ice grape has strict requirements on growing conditions and is controlled and affected by factors such as geography, hydrology, climate, and soil environment. Growing in high-temperature regions, ice grapes can survive freezing at minus 7-15°C, and can still maintain their activity. The definition of ice wine in the "National Standard" is: to delay the harvest of the grapes, keep the grapes on the branches for a certain period of time when the temperature is lower than -7°C, freeze, harvest, press and ferment in the frozen state, and brew. made wine. The definition of the Canadian VQA standard is: wine made from grapes that are naturally frozen on the vine at a temperature below -8°C. Due to the requir...
