First, choose suitable plots and robust seedlings. The adaptability of the grapes to the soil is strong. Soils such as sand, sandy loam, loam, gravelly soil, and light saline-alkali soil can all be planted. However, sandy loam is most suitable and sandy soil blocks should be planted as far as possible. In order to improve the survival rate and early high yield of transplanting, on the basis of the selection of varieties with strong cold tolerance, we must select excellent seedlings with well-developed root system, abundant branch shoots, no pests and diseases, and no mechanical damage.
Second, fine soil fertility, improve planting quality. After the plot has been selected for ploughing and leveling, dig pits according to the scheduled line spacing. The upper diameter of the pit is 80 cm and the bottom diameter is 40 cm. Before planting, the roots and branches of the seedlings should be properly trimmed. The root system should be retained as much as possible, and the trees should be soaked in the roots in time and sterilized. 30-40 kg of organic fertilizer and 0.5 kg of urea were applied to each pit, and evenly spread into the bottom of the pit, backfilled with 10 cm thick soil, planted 1 grape seedling per pit, filled with water, and then irrigated once to spray a new high-fat film. 800 times the liquid to prevent the bacteria infection, improve the ability of anti-natural disasters, reduce the slow seedling period, water infiltration after the timely use of the earth to cover the pit.
Third, strengthen management after planting. About 7 days after planting, the soil is protected from cold and hoeing. The thickness of the mound is generally about 30 cm. It is recommended that general tree protection be used to insulate and prevent freezing, so as to facilitate the security and security of seedlings for the winter. After the frost blooms in the coming year, take the cold soil pile in due course and pour water once; before germination, cut 2-3 buds; after germination, touch the excess buds and pick up the tips; when the main shoot grows to 50 cm long , carry out topping. Later transferred to normal field management.
