The grape propagation method is mainly division method, but cuttings can also be propagated. Grape rhizomes must be soaked in water for 2-3 hours before planting. Allow the grape rhizomes to completely absorb the water. The recommended distance between vines is 6 feet - 8 feet. Buried cold protection method: The total burial method does not need to dig trenches on the ground and is directly buried in the ground to prevent cold. The thickness of the covering soil depends on the local absolute minimum temperature and the cold resistance of the variety. Generally, the covering soil thickness is about 20 cm when the temperature is -15°C in winter, and -17°C when the minimum temperature is 25 cm in winter. The lower the temperature, the thicker the covering soil. For some varieties with strong cold resistance, such as Kyoho, Baijiao, etc., the covering soil can be thinner. The minimum temperature required for grape growth is about 12℃-15℃, the minimum base temperature is about 10℃-13℃, the optimal temperature during the flowering period is about 20℃, and the optimal temperature during the fruit expansion period is 20℃-30℃. When the temperature difference between day and night is large, the color and sugar content are better.
