The invention discloses a top
grafting and replanting method of citrus. The method comprises the steps of (1) selecting cions, namely, selecting one-year-old pure, healthy, strong-
branch and full-eye mature spring
twig; (2) picking cions, namely, picking the cions in the monitoring or at the forenoon, immediately
cutting of leaves of the picked cions, and remaining 1-2cm protecting buds and thorns at the
handle; (3) storing cions, namely, storing the picked cions through a
polyethylene bag for 2 to 3 months under the temperature of 4.4 to 7.2 DEG C; (5) top
grafting, wherein the top
grafting includes top grafting time, top grafting part and
grafting method; (6) managing after grafting, namely, inspecting the survive rate 15 to 30 days after grafting, removing a film 15 to 30 days after grafting in summer, removing the film in the period that the grafting is done in autumn and
sprouting appears in February of the next year,
pruning stock twice after grafting in autumn, and picking the core when the spring
twig grows in 20 to 25cm. With the adoption of the top grafting and replanting method, the varieties of the citrus are enriched, the demand of consumers can be met, the maturation period after grafting is reduced, and as a result, the economic benefit is increased.
