Problems solved by technology

Commonly used remote grafting methods mostly adopt grafting and seed bud grafting. The grafting process simply uses the principle of phloem cambium healing, which has a certain limit on the quality of grafting, especially in plants of different families with poor affinity. to stand out

Embodiment 1

[0016] The present embodiment is a distant grafting method of Camellia oleifera as rootstock to graft Camellia japonica.

[0017] 1. Grafting time

[0018] Due to the hard texture of the xylem of Camellia oleifera, the grafting was carried out on February 15.

[0019] 2. Scion selection and collection

[0020] On February 13th, choose 1-year-old shoots with a diameter of 2-3cm, robust growth, and semi-lignified camellia plants, with a length of 30-35cm, and each of them contains 6-8 bud eyes (which can be divided into 3 scions). After cutting off the leaves, the fringes are sealed with wax, put in a plastic bag for later use, and the storage temperature is 5-10 °C.

[0021] 3. Rootstock shaping

[0022] According to the trunk structure of the tree vigor, the branches and trunks of the grafting position are selected, that is, the reasonable distribution of the scion growth space. Some auxiliary branches are reserved and other branches are cut off to maintain the integrity ...

Abstract

The invention discloses a medulla combined distant grafting method, which comprises the following steps of: 1, cutting a stock; 2, cutting a cion; 3, inserting the cion; 4, wrapping up; and 5, managing after grafting. The invention solves the problem that after garden plants subjected to distant hybrid grafting survive, the plants in an early stage have normal nutritional status, but when the stock and the cion are healed after a certain period of time, the inclusiveness is gradually changed into mutual exclusion, so that the plant vigor is low, the growth vigor is weakened or the plants stop growing and are yellowed, and individual plants are even dead. By the medulla combined grafting method, the defect can be effectively made up, and a new plant line with high quality and vigorous vitality is cultured.

Description

technical field [0001] The present invention relates to a method for distal grafting of medulla combined. Background technique [0002] Plant grafting plays an important role in preserving germplasm resources and new mutant genes, improving production efficiency, improving crop quality, etc., and is of great significance for crop disease resistance breeding; it is the renewal of plant species, rapid propagation of new varieties and rescue of damaged trees. An effective and practical technique for the body. Grafting is one of the most effective and direct means in the improvement of horticultural plant varieties or the introduction and cultivation of new varieties. By making full use of territorial resources and fine varieties, research results can be obtained in a relatively short period of time. [0003] Distant grafting refers to the grafting between different species or more distantly related species in plant taxonomy, especially between plants of different families. B...
