1. Frozen ice method. Place the grape vines bundled and trimmed on the ground, and cover the branches on the branches in the middle and late October. Cover the soil 5-8 cm and cover the soil with a straw bag. When the temperature decreases from November to December, the water is continuously poured twice on the cover to make it freeze, thereby isolating the plant from the outside world and achieving the purpose of safe wintering.

2. The four-layer grape cold-proof method of sand film and leaf stalk. First cover the branches with 20 cm thick sand, cover the sand with a layer of mulch, spread a layer of corn leaf with a thickness of about 10 cm on the mulch, and apply 60 cm of corn stalk on the leaf to reach the sand vine, the membrane moisturizing, and the leaf encryption. The effect of straw warmth. The first three layers of coverage should be carried out in the middle and late October. The latter layer should be carried out after freezing.

3, sawdust grape cold method. The trimmed grape vines are bundled into bundles, which are then wrapped with 1-2 layers of straw or sack pieces, then covered with 15-20 cm thick sawdust, and then covered with a plastic film, and the film is compacted with soil. Sawdust and plastic film are readily available and the material can be used continuously for 3 years.

4, plastic film grape cold method. With the continuous improvement of the cold-proof technology, in recent years, there has been a cold-proof method covered with plastic film. For the shape of the dragon-dragon tree, it is also necessary to put the grape vines up, and the raised branches should be flattened to avoid puncturing the plastic film. . After the plate is flattened, the soil is slightly pressed, and then covered with a black plastic film of 1.4 m width and 0.07 mm. The film is surrounded by soil compaction. This cold-proof method requires less labor, relatively low labor intensity, and because the cold-proof plastic film can be reused, the cost does not increase.

5, comprehensive cultivation wintering method. In the process of grape growth management, the appropriate amount of nitrogen fertilizer should be applied, and sufficient amount of phosphorus and potassium fertilizer should be applied. It is strictly forbidden to apply nitrogen fertilizer in the late growth period, which is beneficial to flower bud differentiation, full buds and full of branches. Moderate light cut in winter, germination in early spring and then re-cut. Watering the winter water to keep the soil temperature constant, it is strictly forbidden to water a lot in the late growth period, resulting in a long length. Gradually grasp the management of grape pests and diseases, reduce the pests and diseases of grapes, and increase the accumulation of branches. The combined use of these measures ensures that the grapes are safe for winter.

6, hollow grape cold method. In the ditch, use bricks and adobe to form a trough shape, and put the branches of the winter shears in the middle, scaffold with wooden poles, put stalks and grass bags, cover 20-30 cm; then cover the leaves or firewood 50 cm, leaving a few ventilation holes along the ground, can be temperature-controlled ventilation at any time; closed at 0 °C, open when the next year is clear.

7, buried the main frozen branch grape cold method. Dig a trench in the courtyard and bury the excavated soil near the main stem of the grape to prevent the root from being frozen. Bundle the branches and place them in the ditch after excavation. When the temperature drops below 0C, fill the ditch with water to make it freeze. This kind of vine is wrapped in ice and can be safely wintered. The water in the ditch is both frozen water and spring germination water. This method works well in the courtyard.
