Embodiment Construction

[0017] A method for breeding and cultivating cold-resistant grapes, carried out as follows:

[0018] 1. Hybrid seed production: Confer the pollen of Vitis vitis vinifera on the stigma of the female parent Vitis vinifera Kyoho flowering and remove the stamens (or reverse crossing, backcrossing), cover the pollinated flower spikes with a paper sleeve, and the hybridization is successful. After the fruit is ripe, picking seeds for storage;

[0019] 2. Acceleration of germination: Put the wet sand mixed with the seeds into a plastic gauze bag, cover it with 10cm thick wet sand, and place it in the shade for 2 months. 12 days before sowing, soak the seed bag in clean water for 2 days, remove Cover with wet fiber cloth after emergence, and keep the temperature at 25°C-28°C for germination. After 8 days, the seed shells begin to crack and become white, and they can be sown;

[0020] 3. Sowing for soil preparation: sow on the plowed and flat land, with a row spacing of 40cm and a hei...

Abstract

The breeding and cultivating process of cold tolerant grape variety includes the following steps: pollinating the pollen of ussurian grape to blossom of female parent grape to hybridize, collecting the hybrid seed, seeding the hybrid seed, leaving 1 or 2 main vines, overwintering naturally, marking snow line in the grape vine, selecting excellent plant after germination, cutting twigs from the excellent plant as scion, grafting to ussurian grape stock, coating the scion with cotton ball and plastic, injecting water to the cotton ball until the scion survives, collecting the surviving branch before winter, inserting in the next spring for raising seedling, and transplanting. Thus obtained grape variety has high cold tolerance.

Description

technical field [0001] The invention belongs to the technical field of agricultural cultivation, in particular to a method for breeding and cultivating cold-resistant grapes. Background technique [0002] There are many varieties of viticulture, among which the grapes that can be eaten fresh and dried have poor cold resistance. In northern my country, it is cold in winter. Before the grapes are planted in winter, the grape branches must be removed from the shelf and buried with soil in order to survive the winter safely. In the spring of the second year, the grape branches will be dug out from the buried soil and placed on the shelf, which is labor-intensive, labor-intensive and time-consuming. . A kind of mountain grape cultivated in Northeast China has good cold resistance, but this grape can only be used for wine making, it is not good for fresh food, and its yield is not high enough. Especially in my country, more than 6 million mu of land is used for development and co...
