Pressure vines cover the main vines in the direction of creeping, dig 30 cm deep ditch, put the vines into the ditch, cultivate the semi-trenchy soil, and then water the ditch, fill the ditch with water until the water penetrates, cover it with straw bags or mats. , so that the vines sprout in the earth and the Soviet Union. After 15 days, new roots can be grown from the half dead roots, and the resurrected branches can be gently raised and placed on shelves.
Under the above method and requirements, the main vine was buried in the trenches, and the soil around the root neck of the frozen plants (2 meters before the frame and 1.5 meters behind the frame) was dug deep 40-50 cm, and the dead roots were cut. Keep half dead roots, then spread 10 cm thick humus soil, irrigated with water, and then cover the soil to allow it to resume growth.
Shrink the vines to the lightly frozen plants. When they are germinating, cut the long vines for a period of time so as to concentrate the nutrients and restore growth. Shrinking and cutting positions should be followed by timely application of adequate amount of fertilizer, combined with loose soil, increase soil temperature and air permeability, and promote new root growth. From the top to the bottom, the dendrite gradually shrinks and shrinks. To cut off the cold-damaged shoots, loosen the tree disk, increase the decomposed organic fertilizer, and water it in proper amount. As the temperature rises, it can gradually resurrect.
