Grapes are one of the oldest fruit tree species in the world, planted in a very wide range, and are one of the common fruits in life. Grapes have different fruit colors depending on their variety, and the fruit color also has different fruit colors. So, how to build a grapevine? How many kinds of trellises are commonly used? Which trellis is better? Let's talk to you today.
Horizontal frame: build beams on the pillars in the vineyard, pull wire on the beams into a mesh, the height of the two sides is almost equal, forming a horizontal frame, the top surface as a whole is about two meters from the ground, the spacing of the pillars is about 4 meters, and the anchor stone is used to make the column and the traction backbone line on it tightly fixed. The backbone line is made of No. 8 wire, and the other branch lines are made of No. 12 wire, and the distance between the branches is 50 cm. This type of frame is suitable for large areas of flat or sloped land. The shelf-type shelf surface is flat, stable and firm, two meters off the ground, reaching out to pick and not affect the normal passage, the fruit hanging area is relatively high, can reduce the impact of disease is also conducive to the entire buried soil cold protection is conducive to management. This racking formula can be used for grape varieties with a long growing period or strong growth.
Tilting frame: The trellis from the appearance of the oblique trend, near the root out of the height of about 1.5 meters, the highest part of the roof of the frame should not exceed 2.5 meters, in the pillar set beam traction wire, the length of the shelf is not fixed according to the grape variety growth trend to determine, the growth of the vigorous shelf length is slightly longer. The vines are hung from the beams to bring them into fruiting earlier. The grapes are fertile and the branches are easy to renew. This kind of shelf type is easy to manage, the recovery will be relatively fast after the update, the tree potential will be better in all aspects, and the yield will be relatively stable. It is generally used in greenhouse grape cultivation in the cold areas of the north and is the first choice for our buried soil cold protection area.
Roof ridge: Consists of two inclined small trellises or large trellis opposite the head, the upper part is the lower part of the triangle extending vertically downwards, shaped like a roof ridge and named. The advantage is that it eliminates the need for a row of tall pillars, and the rack is strong, and the others are the same as the size of the trellis. In addition, the shelf shade avoidance effect, ornamentality, grape fruit rate are relatively good, but the tree potential management is not very convenient. General terrain can be used.
