Top grafting and replanting method of citrus

Abstract

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.

Description

technical field [0001] The invention relates to the technical field of plant cultivation, in particular to a method for citrus high grafting and planting replacement. Background technique [0002] There are many ways to propagate citrus seedlings, such as seeding, layering, cutting and grafting. At present, the grafting method is still the best and common method. It is also a mature citrus seedling raising technology. [0003] The grafted seedlings of citrus are combined by scion and rootstock. The rootstock is the plant that bears the scion during grafting and propagation. It can be the whole fruit tree, or the root segment or branch segment of the tree body, which plays the role of fixing and supporting the scion, and forms the plant growth and fruit after healing with the scion. Commonly used rootstocks for grafting citrus are trifoliate orange, orange, sour orange, sweet orange, sour lemon, orange, pomelo, etc. [0004] Citrus is the most important group of plants in c...

Problems solved by technology

[0005] At present, many farmers have large citrus forests, but most growers do not have systematic high-inoculation and replacement technology. Their harvest and citrus quality depend to a large extent on the environment and climate, so a good high-inoculation and replacement technology should be developed Very necessary
