After the grape is put on the shelf and managed, the vines and buds of the grapes are more resistant to cold, but the roots are easily frozen. Therefore, it is necessary to maintain a multi-pronged approach to ensure that the grapes safely pass through the winter.
One trick: Before and after the winter solstice, the grape after the autumn harvest should be placed in a ditch. At the same time, hibernation should be used to improve the quality of hibernation and allow the plants to “ear off early and get up earlyâ€, so as to accumulate strong spiritual energy for the overwintering plant to recover in early spring. And cover it with a straw bag in the evening, open it during the day, and pay attention to insulation, antifreeze and cold protection.
Two tricks: buried sand and cold, first cut the winter branches of grape vines along the ditch tied, covered with sand or soil 20 or 30 centimeters, and then when the soil is frozen 10 centimeters, and then covered with leaves and firewood 50 centimeters, four weeks extension . At the same time, a few stalks of sorghum (sorghum stalks) were planted and exposed at the top to maintain ventilation and light transmission.
Three strokes: hollow and cold, brick and adobe in the ditch into a trough type, the winter after cutting the branches bundled and sprayed on the top of the trees to protect the general insulation to reduce frost damage, and then placed in the middle, with a wooden pole scaffolding Put stalks and grass bags, cover 20 to 30 centimeters, and then cover the leaves or fireweed 50 centimeters. Leave a few vent holes along the ground to measure the temperature and ventilation at any time to promote the budding of the grapes. .
