1. Choose suitable plots and robust seedlings. The adaptability of the grapes to the soil is strong, sandy soil, sandy loam soil, loam, gravel soil, light saline alkaline soil, etc. can all be planted, but sandy loam is the most suitable. In order to improve the survival rate of transplanting and early high yield, based on the selection of varieties with strong cold tolerance, we must choose superior seedlings with well-developed root system, abundant branch shoots, no pests and diseases, and no mechanical injury.
2. Fine soil preparation fertilization. After the plot has been selected and leveled, 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 shoots of the seedlings should be properly trimmed and the root system should be retained as much as possible. Apply 30 to 40 kg of organic fertilizer and 0.5 kg of urea to each pit, and apply 10 cm of soil back evenly to the bottom of the pit. Plant 1 seedling per pit, fill the soil after compaction, and fill the pit with water after seepage. .
3. Strengthen post-plant management. After 7 days of planting, the soil was kept cold and protected. The earth mound was about 30 cm thick. After the frost in the coming year, go to the pile of cold soil and pour water once. Two to three buds were cut before germination; after germination, excess buds were removed and the axillary tip was picked up. When the main tip is 50 centimeters long, it is picked up and later transferred to normal management.
