Wine grape inverted broom-shaped single-arm trellis shaping method

The invention aims to provide a shaping method for a wine grape inverted-broom-shaped single-arm trellis, and belongs to the technical field of grape planting.In shaping of the wine grape inverted-broom-shaped single-arm trellis, the base of a main vine of a single-arm vine keeps 30 degrees with the ground, and then the single-arm vine obliquely ascends to the position of a first steel wire to form a broom handle; then the branches and tendrils are horizontally bound and fixed along a first steel wire to form a horizontal single-arm fruiting main vine with the length equal to the plant spacing, namely a broom back; annual fruiting new shoots growing on the horizontal mother vines are evenly selected and reserved at the interval of about 10 cm and vertically introduced and bound into the second row of steel wires, the third row of steel wires and the fourth row of steel wires to form broom threads, the two rows of steel wires are bound and tensioned every 1 m, and the broom threads are the foundation for formi
