1. Choose suitable plots and robust seedlings. The adaptability of the grapes to the soil is very strong. Sand, sandy loam, loam, gravel soil, light saline soil can be planted, but sandy loam is the most suitable. In order to improve the survival rate of transplanting and early and high yield, on the basis of selecting strong varieties with cold tolerance, it is necessary to select superior seedlings with developed roots, full buds, no pests and diseases, no mechanical injuries.
2. Fine soil preparation. After the plot is selected for 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 per pot and 0.5 kg of urea. After being evenly sprinkled into the bottom of the pit, backfill 10 cm of soil, plant 1 seedling per pit, fill the soil and compact it, and then pour the water with water. .
3. Strengthen post-plant management. After 7 days of planting, the soil was kept cold and protected, and the mound was about 30 cm thick. After the night frost in the coming year, remove the cold-proof mound and pour a proper amount of water. Cut 2 to 3 buds before germination; after germination, remove excess buds and topping the secondary shoots. When the main tip is 50 cm long, it is topped and then transferred to normal management.
