摘要:【中文】本发明公开了一种葡萄嫩芽嫁接育苗的方法,包括如下步骤:(1)砧木的培育:砧木母本树新梢长至7片叶时摘心,摘心一周后采集新梢,每两个芽为一个枝段,扦插入育苗盘中,将育苗盘置于苗床上,一周后降低空气湿度至70%炼苗,5天后扦插苗即可换至营养杯出床;营养杯苗移至避雨棚中培养,1个月后进行嫁接;(2)接穗的培育:从接穗母本树上采集5‑6片叶的新梢上的梢尖2‑3片叶嫩芽及其下单芽枝段作为接穗;(3)嫁接:采用劈接法进行嫁接;嫁接口用小夹子固定;(4)嫁接后的管理:嫁接后的苗木移至育苗床进行保湿,再转移避雨棚管理1个月后,接穗长至5‑6片叶时即可成苗。本发明葡萄嫁接成活率高,育苗周期短。 【EN】The invention discloses a method for grafting and seedling raising of grape tender shoots, which comprises the following steps: (1) cultivation of the rootstock: pinching when the young shoots of the stock female parent tree grow to 7 leaves, collecting the young shoots after pinching for one week, cutting every two shoots into a branch section, putting the branch section into a seedling tray, putting the seedling tray on a seedling bed, reducing the air humidity to 70% after one week, hardening seedlings, and changing the cutting seedlings to a nutrition cup after 5 days to come out of the bed; transplanting the nutrition cup seedlings into a rain shelter for culture, and grafting after 1 month; (2) and (3) cultivating scions: collecting shoot tips of 2-3 leaves on the new shoots of 5-6 leaves from the scion female parent tree and taking the shoot tips and lower single shoot branches thereof as scions; (3) grafting: grafting by cleft grafting; the grafting opening is fixed by a small clamp; (4) and (3) management after grafting: and transferring the grafted nursery stock to a seedling bed for moisturizing, transferring to a rain shelter for management for 1 month, and growing the scion to 5-6 leaves to obtain the seedling. The grape grafting survival rate is high, and the seedling period is short.
