First, choose the appropriate plots and robust seedlings. The adaptability of the grapes to the soil is very strong. Sand, sandy loam, loam, gravel soil, light saline soil and other soils can be planted, but sandy loam is the most suitable, and sandy loam should be selected as much as possible. In order to improve the survival rate of transplanting and the early high yield, on the basis of selecting the varieties with strong cold tolerance, it is necessary to select the superior seedlings with developed roots, full buds, no pests and diseases, no mechanical damage.
Second, fine soil preparation and fertilization to improve planting quality. After the plot is selected for ploughing and leveling, the pits are pitted according to the predetermined row spacing. The upper diameter of the pit is 80 cm and the bottom diameter is 40 cm. The roots and shoots of the seedlings should be properly trimmed before planting, and the roots should be preserved as much as possible. Apply 30-40 kg of organic fertilizer and 0.5 kg of urea per pit, evenly spread into the bottom of the pit, backfill 10 cm of soil, plant 1 grape seedling per pit, fill the soil after compaction, and pour water after water infiltration. Use soil to cover the pit.
Third, strengthen post-plant management. After 7 days of planting, the soil should be kept cold and protected in a timely manner. The thickness of the mound is generally about 30 cm, which is beneficial to protect the seedlings and seedlings for safe winter. After the night cream in the coming year, timely remove the cold-proof mound and pour the water in a proper amount; before germination, cut 2 to 3 buds; after germination, touch the excess buds and pick the tops; when the main shoot grows to 50 cm long At the time, picking the heart. Later transferred to normal field management.
