Embodiment

[0017] A method for grafting seedlings, comprising the following steps:

[0018] (1) selection of rootstock: select no pests and diseases, no mechanical damage, trees with strong vitality as rootstock;

[0019] (2) the selection of scion: select 3-4 shoots with full buds, substantial tissue and no pests from the seedlings to be grafted, cut and grow into 40-50cm branches as scion;

[0020] wherein the selected rootstock and scion belong to the same species of trees;

[0021] (3) Combination: Combine when the average temperature is 22-26°C, use a sterilized knife to cut the joint part of the rootstock according to a 30-degree slope, cut off the phloem of the lower part of the scion by 1-1.2cm, expose the cambium, and form the rootstock layer combined with the scion cambium;

[0022] The utensils used in the bonding process must be strictly sterilized, and the hands are also sterilized with 75% alcohol, and then combined after the disinfectant is dry. When combining, the cambi...

Abstract

The invention discloses a nursery stock grafting method which comprises the following steps of (1) selection of a stock, selection of a scion, (3) combination, (4) treatment of the combined portion and (5) timely watering after combination. In the combination process, the combined part of the stock is cut open to form a 30-degree oblique plane through a disinfected knife, the phloem of the lower portion of the scion is cut off by 1 cm to 1.2 cm, so that the cambium is exposed, the cambium of the stock is combined with the cambium of the scion. The grafted nursery stock is managed in a conventional method. According to the nursery stock grafting method, the combination area between the cambium of the stock and the cambium of the scion is enlarged, combination is tighter, the grafting survival rate can be increased, the survival rate can achieve 80 percent to 90 percent, the germination rate of the nursery stock after grafting can be increased at the same time, and the nursery stock after grafting can survive ahead of time by 10 days to 15 days.

Description

technical field [0001] The invention belongs to the technical field of plant grafting, and in particular relates to a seedling grafting method. Background technique [0002] Grafting is the process of connecting the branches or buds of one plant to the stem or root of another plant, bringing the wounded surfaces of the two parts closer together, allowing the cells to proliferate and heal each other to grow into a complete plant. The plant body used to receive is called rootstock; the branch or bud that is connected is called scion. Grafting belongs to vegetative propagation in asexual reproduction. Grafting can not only maintain the excellent traits of scion plant varieties, but also take advantage of other advantages of its rootstocks, increase species yield, improve varieties, and improve plant resistance to diseases and insect pests. economic value. However, the existing grafting technology has a slow survival rate and a low survival rate of only 60-65%. Contents of t...
