Grapevine management technology after off the shelf
Grapevine shoots and bud eyes are more resistant to cold, but the root system is easily frosted. Therefore, after the grapes are racked, they must be multi-pronged to ensure that the grapes safely pass through the winter. First, before and after the winter solstice, the grape after the autumn cut should be placed in the ditch, and at the same time, use Hibernian music to improve the quality of hibernation, so that the plants can “ear off early and get up earlyâ€, so as to accumulate strong spiritual energy for the overwintering plants. And cover it with a straw bag in the evening, open it during the day, and pay attention to insulation, antifreeze and cold protection. Second, buried sand and cold, first cut the winter grape branches along the ditch, use sand or soil to cover 20 or 30 cm, then when the soil is frozen 10 cm, then cover 50 cm with leaves and firewood, extend 1 meter. At the same time, a few stalks of sorghum (sorghum stalks) were planted and exposed at the top to maintain ventilation and light transmission. Third, hollow and cold, in the ditch with bricks and adobe built into a trough, the branches of the winter cut after the bale and spray on the top of the trees to protect the general insulation to reduce frost damage, and then placed in the middle, with wood poles above the shed, Put stalks of straw and grass bags, cover 20 to 30 cm, and then cover the leaves or firewood 50 cm, along the ground to leave a few air holes, at any time temperature ventilation, to promote grape sprouting, until the next spring can be opened.
