How to determine the row spacing of grape plants
The planting direction of grape generally chooses the north-south direction is better, can better accept the light, but also make the shelf surface basically vertical to the dominant wind direction of the growing season, which can reduce the wind damage. However, if it is limited by the land, it can also be planted in the east-west direction. According to the choice of cultivation scaffolding, the row spacing of hedgerow is 2 to 2.8 meters, and that of scaffolding is 4 to 6 meters. The distance between the cultivated plants is 0.5-0.6 meters, and the one-stop pruning method is adopted. In addition, attention must be paid to the preparation of the planting ditch before planting. Generally, the planting ditch is 0.8-1.0 m deep and 0.8-1.0 m wide, and at least 0.6 m wide and 0.6 m deep should be dug. Fully mature organic fertilizer should be applied at the bottom of the ditch, and the topsoil should be backfilled along 0.4 m from the ditch. Because the grape is a fertilizer-loving and water-loving plant, the soil should be deeply ploughed and improved before planting to create suitable growth conditions for the root system, so that the plant can maintain strong, stable and high yield.
