1. Apply fertilizer. Before harvesting, the grapes were planted under a deep ditch before the winter harvest, 5000 kg of organic fertilizer was applied to Mushi, and 40-50 kg of superphosphate was mixed.
2. Do a good winter cut. After the deciduous grapes, it was carried out until the soil was buried and kept cold. The single main vine Duron dry shape, leaving 5-7 result branches, the results of each branch of a single branch update, leaving enough 2-3 full shoot short cut, the main vine extension branches left 4 buds short, strains The amount of bud left is controlled at about 20.
3. Clean the orchard. After the winter cut, the remaining branches, leaves, and fruits on the ground are removed and burned or buried deeply. At the same time, 5 Baume degree lime sulfur was sprayed on branches and ground.
4. Demolition frame tied vines. Remove the vines and gently tie them down. Slowly lower them in the cold direction. Be careful not to strain the branches with too much force.
5. Enclose the frozen water. In the winter, 10 days before the grapes are buried in cold soil, the frozen water is poured once.
6. Buried against cold. The hibernation temperature of the roots of the grapes should be kept above -6°C. The cold-proof soil must be taken between the two sides of the vine's main trunk. It must not be too close to the roots to avoid damaging the roots. The soil must be finely crushed, earth pressure ridges must be photographed, and the vines should be 30 cm thick on the soil, and the roots should be thick and solid. Where there are irrigation conditions, the trenches should be filled with water and frozen into ice after being frozen. This will not only reduce the thickness of the frozen soil, but also help the roots to overwinter and late spring drought. Where there is no irrigation condition, weeds and other items can also be used to cover the trenches to prevent the grapes from freezing. When it is found that cracks appear on the cold-proof soil after entering the winter, the cracks should be covered with soil in time. When the weather is particularly cold, pile up some cold-proof materials such as fireweed on the cold soil to ensure that the grapes are not frozen.
