“左优红”硬枝扦插(自根)生根率平均为90.1%,成苗率87.1%。“左优红”与“贝达”条和苗木硬枝嫁接生根率平均为95.4%。催根幼苗根系多,移栽苗圃地成活率高,出圃成苗率94.3%。“左优红”与“公酿1号”和“双红”条和苗木硬枝嫁接生根率平均52.3%,成苗率平均仅为46.7%,分别低于“左优红”硬枝扦插(自根)和与“贝达”条和苗木嫁接40.4%和47.6%。“双红”、“公酿1号”条和苗木不宜做“左优红”硬枝嫁接的砧木。
The rooting rate of “Zuyouhong” hardwood cutting (self-rooting) was 90.1% on average, and the seedling rate was 87.1%. The average rooting percentages of “Zuo You Hong” and “Beida” and grafted seedlings were 95.4%. Promote the root seedlings and more transplanting nursery high survival rate, the nursery seedlings rate of 94.3%. The rooting rates of “Zuo You Hong”, “Gongong 1” and “Shuang Hong” and the grafting of seedling branches were 52.3% and 46.7% on average, respectively, which were lower than that of “Zuoyouhong” Self-root) and 40.4% and 47.6% with “Beida” strips and seedlings. “Double red”, “Public stuffing 1” and nursery stock should not do “left red” hardwood graft rootstock.
