After the grape is removed from the shelf, the grapevines and buds are more resistant to cold, but the roots are more susceptible to freezing, so it is necessary to multiply and keep the grapes safe for winter.
One trick: Before and after the winter solstice, put the grapes in the autumn cut in the ditch, and at the same time apply hibernation to improve the quality of hibernation, let the plants "get up early and get up early", and develop strong spiritual energy for the overwintering plants in the early spring. And cover it with a straw bag at night, open during the day, pay attention to heat preservation, antifreeze and cold protection.
Two strokes: buried sand and cold, first bundle the winter grape vines along the ditch, cover it with sand or soil for 20 or 30 centimeters, then wait 10 cm for the soil, then cover 50 cm with leaves and firewood, and extend 1 m around. . At the same time, several stalks (sorghum stalks) are buried, and the upper end is exposed to maintain ventilation and light transmission.
Three strokes: hollow and cold-proof, use bricks and adobe to form a trough in the ditch, bundle the branches after winter shearing and spray the tree to protect the frost damage, then put it in the middle, with a wooden pole scaffolding Put the straw and grass bag, cover 20 to 30 cm, and then cover the leaves or firewood 50 cm, leave a few ventilation holes along the ground, you can measure the temperature and ventilation at any time, promote the grape sprouting, until the spring of the next year .
