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] This embodiment is a method for remote grafting of Camellia oleifera as rootstock grafting Camellia japonica.

[0017] 1. Grafting time

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

[0019] 2. Scion selection and collection

[0020] On February 13, choose the one-year-old branches of the camellia plant with a diameter of 2-3cm, strong growth, and semi-ligninization. The spikes are 30-35cm long, and each spike contains 6-8 bud eyes (which can be divided into 3 scions). After cutting the leaves, the cuttings are sealed with wax and placed in a plastic bag for later use. The storage temperature is 5-10℃.

[0021] 3. Rootstock shaping

[0022] According to the trunk structure of the tree vigor, select the branches of the grafting position, that is, the reasonable distribution of the growth space of the scion. Retain some auxiliary branches and cut off other branches to keep the grafting cross-section intact and prepare ...

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 invention relates to a remote grafting method of pith joint. Background technique [0002] Plant grafting plays an important role in preserving germplasm resources and new mutant genes, improving production efficiency, improving crop quality, etc. It is of great significance to the disease-resistant breeding of crops; it is the renewal of plant species, the rapid propagation of new varieties and the rescue of damaged trees. An effective practical technique for the body. Grafting is one of the most effective and direct methods in the improvement of horticultural plant varieties or the introduction and cultivation of new varieties. Making full use of territorial resources and fine varieties can obtain research results 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. Because the grafting affi...
