The frame is slightly inclined to the ground, slightly lower near the tree and slightly higher away from the tree. Generally, the flat garden is inclined about 5, and the hilly garden can be erected along the slope, and the height is as convenient as possible for the management of branches and vines. The advantages are that it is convenient to get on and off the shelf when burying soil in cold conditions, especially it can make full use of hillside for scattered hole planting and use local materials as scaffolding, reducing ground management and scaffolding investment. The disadvantage is that it is not convenient to manage the shelf during the growing period. The vast majority of grape old areas such as Shanxi, Hebei and Liaoning in China adopt this framework. According to planting row spacing and target tree size, it can be divided into four types: greenhouse, shed, hedge shed and single dragon.

(1) The large trellis is more than 6 meters long, which is the main traditional trellis in old grape producing areas such as Qingxu in Shanxi and Changli in Hebei. The general structure of this frame is that the height of the frame root near one end of the plant is 1 ~ 1.5m, the height of the frame far from the plant is slightly 2 ~ 2.4m, and the frame length is 7 ~ 15m or longer. Plant spacing varies with different pruning forms, mostly 1 ~ 2 meters. The methods of shaping and pruning mostly use the short tip pruning technology of dragon stem, and also use the mixed pruning technology of fan-shaped long, medium and short tips.

② The length of scaffolding is less than 6m, and the height of scaffolding is also reduced. The frame structure is similar to a greenhouse. Its characteristics basically overcome the shortcomings of large shed, fast crown formation, high early yield, small plant body, easy regulation and control, and low requirements for soil, fertilizer and water conditions. Widely used in vineyards in hilly areas of Shanxi, Hebei, Liaoning and other provinces. The shaping and pruning method of small scaffolding is still a combination of dragon dry short tip pruning and fan-shaped long, medium and short tip pruning.

④ Yi Long box is the simplest box. Its structure is that the existing simple frame materials, such as bamboo poles, branches, waste wood and so on. , used to erect long-stem grape vines every 1 ~ 2 meters so as to be high from the ground. The specific spacing mainly depends on the thickness and hardness of the main rattan. The thicker and harder parts can be farther away, and the softer parts should be closer. This kind of frame is characterized by using the least frame materials, being very economical and flexible, fully exposed to light on the frame surface, good fruit coloring and high quality. However, due to the small frame surface, the growth of plants is inhibited and the yield is low. It is mainly used to manage scattered vineyards on rough slopes. Yuci, Shanxi, Zhuolu, Hebei, Dazeshan, Shandong and other places have applications. Its pruning form can adopt the pruning technology of long stem and short tip.

Column frame, also called column frame, is the simplest frame. That is, next to each grape, stand a short wooden column or other temporary frame material, the height of which is close to the height of the tree. The shaping and pruning methods of plants adopt the techniques of head pruning and short tip pruning described later. The trunk is 0.6 ~ 1.2 meters high, and branches and fruiting vines are cultivated at the top. The new vines born that year are not tied, let them hang around naturally. When the trunk is continuously cultivated for 5-8 years, and the diameter of the trunk reaches 7-8 cm, which can support the overall weight of the trunk, the temporary support can be removed and cultivated without frame. This kind of frame is only suitable for warm areas where there is no need to bury the soil to prevent cold and winter. It is characterized by low framing cost and labor-saving management after molding, but it requires high plastic technology in the early stage, and it is difficult to control the height of trees and cultivate free-standing trunks, resulting in late early fruiting and low yield. Varieties should be cold-resistant, with hard branches, strong uprightness and weak growth.
