Single-cross double-V-shaped grape trellis

The utility model provides a single-cross double-V-shaped grape trellis, and belongs to the technical field of grape cultivation. The single-cross double-V-shaped grape trellis comprises a plurality of columns; each column is successively provided with a first cross arm and a second cross arm from bottom to top; each column is also provided with an upper wire penetrating hole and a lower wire penetrating hole; each upper wire penetrating hole is positioned between the corresponding first cross arm and the corresponding second cross arm; and each lower wire penetrating hole is positioned below the corresponding first cross arm. Two ends of the first cross arms and two ends of the second cross arms are respectively erected with drawing wires, drawing wires respectively pass through the upper wire penetrating holes and the lower wire penetrating holes, two adjacent columns are connected via the drawing wires at corresponding positions. According to the single-cross double-V-shaped grape trellis, photosynthetic intensity is enhanced, canopy photosynthetic areas are increased, grape yield is increased, and fruit quality is improved.
