1, full ground burying method

After pruning, tie the branches and vines together, slowly press them on the ground, and then cover them tightly with fine soil. The thickness of the covering soil depends on the local absolute minimum temperature and the cold resistance of the varieties. Generally, in winter, the soil cover is about 20 cm when the temperature is-15℃, and 25 cm when the temperature is-17℃. The lower the temperature, the thicker the covering soil.

2. Full underground burial method

Dig deeper between the grapes and cover them with soil. In extremely cold places, in order to strengthen the cold-proof effect, before covering the soil, the plants can be covered with a layer of plastic film, hay or leaves. This method is suitable for scaffolding and mature gardens with many branches and vines.

3, local buried soil method (root neck covering soil)

In some areas where the absolute minimum temperature in winter is higher than-15℃, plants should not be taken off the shelves in winter, and a mound with a height of 30-50 cm should be piled at the base of plants to protect the roots and necks from freezing. Generally speaking, the depth of this soil cover is thinner in loam and flat vineyards, and thicker in sandy soil and mountain vineyards. For some plants grafted and transplanted that year, although the lowest temperature in winter can't reach-17℃, the plants grow vigorously, fall leaves late and have many fruits, so they should be buried in time to prevent cold.

Expand the technology of information cultivation of grapes;

1. Control the vigorous growth of trees and cut off the secondary branches of summer buds. The winter bud branches near the hair clipper are called winter bud secondary branches. The biggest difference from summer bud secondary branches is that there are scales at the base of winter bud secondary branches.

2. Expand the shelf surface, cultivate fruiting mother branches, and let young trees put into production as soon as possible. On the basis of strengthening the comprehensive management of fertilizer and water, the auxiliary tips are controlled and utilized according to the requirements of the selected frame shape.

3. Concentrate the nutrition of trees for flowering, fruit setting and promoting flower bud differentiation.
