Seedling planting density per unit area is closely related to ventilation and light transmission in orchard and early grape yield. Planting density is high, the early yield is easy to increase, but the ventilation and light transmission of the orchard are poor, and the fruit quality will also be affected. Generally speaking, the number of plants per unit area should depend on varieties, rootstocks, soil fertility and framework. At present, moderate sparse planting is the development direction of pollution-free fresh grape cultivation. The common planting density in greenhouse cultivation is about 4 meters in row spacing and 0.5 ~ 1.0 meters in plant spacing. When cultivated with hedge frame, the row spacing is about 2.5 meters and the plant spacing is 1.0 ~ 2.0 meters when shaped in a fan shape; If a vertical frame with high width is adopted, the row spacing is about 2.5 ~ 3.0 meters, and the plant spacing is appropriately increased to 2.5 ~ 3.5 meters. In the cold-proof areas where soil is buried, the row spacing can be increased to 4.5 ~ 5.0 meters in order to facilitate soil borrowing and cold-proof; In the humid climate in the south, in order to improve the ventilation and light transmission conditions, the row spacing of plants can be appropriately increased.
