单干水平双臂“Y”树形因枝条间营养分配均匀、底部通风透气和顶部采光面大而被广泛应用到高寒冷凉区葡萄设施延迟栽培中,但是多年后(7 a以上)树体逐渐表现出枝条基部光秃,结果部位上移和结果能力下降等不良现象,通过枝组锯、绑、引、拉等修剪措施和根系深翻、断根、施肥等栽培措施,实现了葡萄短期内更新复壮和持续稳产高效栽培。
The single-arm horizontal “Y” tree is widely used in the delayed cultivation of grapes facilities in cold and cold areas due to the uniform nutrition distribution among the branches, the ventilation at the bottom and the large light-emitting surface at the top. But after many years (more than 7 years) Body gradually showed the bare branches at the base, the results of the upper part of the position and the ability to decline and other adverse phenomena, through the branch group sawing, binding, drawing, pulling and other pruning measures and root deep turning, root, fertilization and other cultivation measures to achieve the grape short-term Regeneration within the renewal and sustained and stable and efficient cultivation.
