试验以茎粗0.2~0.3㎝枳砧、纽荷尔脐橙当年生成熟春梢接穗为试材,研究5月25日、6月10日和6月25日芽片腹接对纽荷尔脐橙嫁接成活率及苗木生长的影响。结果表明:从5月25日~6月25日采用茎粗0.2~0.3㎝枳砧与当年生成熟春梢进行芽片腹接成活率均在84.9%以上,与常规春季单芽切接成活率相近;但当年10月上旬苗木高度、茎粗和分枝数量,达不到国家标准《柑橘嫁接苗》的指标,不能当年嫁接当年出圃;在福建省武平县气候条件下生产上广泛推广芽片腹接培育脐橙嫁接苗并在当年出圃是否可行需要进一步进行多年多点试验。
Test with stem diameter of 0.2 ~ 0.3 ㎝ angelica root, Newhall navel oranges were generated in spring scion as the material to study May 25, June 10 and June 25 sprouting on the Newhall navel orange graft Survival rate and seedling growth. The results showed that the surviving rate of sprouts and flaps between the 25th ~ the 25th of June was 0.2% ~ 0.3%, the survival rate was above 84.9%, compared with that of the conventional spring single-sprouts But in early October of the year seedling height, stem diameter and number of branches, less than the national standard “citrus grafted seedlings,” the index can not be the year of grafting out of nursery; Wuping County, Fujian Province in the production of weather conditions widely promote the bud Belly nurturing navel orange grafted seedlings and nursery in the same year is feasible to carry out multi-year trial for many years.
