Study was carried out on high affinity and rooting rate of cleft grafting of hard branch and high viability rate of plants and plants percent transplanted into nursery garden among the varieties of " zuoshanyi " , " shuanghong " , " shuangyou " and " zuoyouhong " of vitis amurensis rupr . ( v . a . r . ) mainly planted 摘要山葡萄生产主栽品种左山一、双红、双优和左优红、用“贝达”做砧木硬枝劈接亲和力、生根率、移栽苗圃地成活率和成苗率高。

Cleft graft of hard branch of those varieties used " gongniang no . 1 " as stocks showed low affinity of stock and scion , rooting rate , plant percent , bloom percent and yield in a productive garden , 3 ~ 4 year - old graft trees showed low fruit while full bloom , 5 ~ 6 year - old graft trees showed a large mount of death 上述品种与“公酿一号”硬枝嫁接、表现接穗与砧木亲和力差、生根和成苗率低、生产建园开花株率和产量低、 3 ~ 4年生树嫁接树出现满树开花坐果少、 5 ~ 6年生树出现大量死亡。
