Problems solved by technology

However, cuttings need to consume a large amount of propagation materials, the cost is high, and the propagation speed of bud stock seedlings is slow and the reproduction coefficient is low, which is not conducive to the large-scale production of asexual propagation of Camellia japonica.

Embodiment 1

[0039]On May 10, 2014, in the periphery of the upper part of the canopy of C. japonica, the semi-lignified branches of the year that were healthy, free from diseases and insect pests, and full of axillary buds were collected as spikes, and then put into a container with ice cubes and wet towels. In the foam box, on the same day, use a single-sided blade to cut the scion into a length of 2.0cm-2.5cm, keep the scion with one leaf and one bud, cut off 1 / 2 of each leaf, and cut off from the 0.3cm-0.5cm above the leaf bud of the scion , the lower end of the leaf bud remains 1.6cm to 2.0cm long, and then straight down from the 0.3cm to 0.5cm below the bud base to a long section with a length of 1.6 to 2.0cm. The xylem can be seen slightly on the long section, and the pith can be seen at the base. Then cut a horse ear-shaped short section at an angle of 20 to 30 degrees on the back of the long section; select a common Camellia oleifera tree with a smooth surface, no pests and diseases...

Embodiment 2

[0043] On May 25, 2014, in the outer periphery of the upper part of the crown of C. japonica, the semi-lignified branches of the year that were healthy, free from diseases and insect pests, and full of axillary buds were collected as spikes, and then put into a container with ice cubes and wet towels. In the foam box, on the same day, use a single-sided blade to cut the scion into a length of 2.0cm-2.5cm, keep the scion with one leaf and one bud, cut off 1 / 2 of each leaf, and cut off from the 0.3cm-0.5cm above the leaf bud of the scion , the lower end of the leaf bud remains 1.6cm-2.0cm long, and then straightly and obliquely pulls a long section with a length of 1.6cm-2.0cm from the 0.3cm-0.5cm below the bud base. The xylem can be seen slightly on the long section, and the pith can be seen at the base , and then cut a 20-30-degree horse-ear-shaped short section on the back of the long section; select a common Camellia oleifera tree with a smooth surface, no pests and diseases,...

Embodiment 3

[0047] On June 10, 2014, in the periphery of the upper part of the crown of C. japonica C. japonica, we collected semi-lignified branches of the year that were healthy, free from diseases and insect pests, and full of axillary buds as cuttings, and then put them in a container with ice cubes and wet towels. In the foam box, on the same day, use a single-sided blade to cut the scion into a length of 2.0cm-2.5cm, keep the scion with one leaf and one bud, cut off 1 / 2 of each leaf, and cut off from the 0.3cm-0.5cm above the leaf bud of the scion , the lower end of the leaf bud remains 1.6cm-2.0cm long, and then straightly and obliquely pulls a long section with a length of 1.6cm-2.0cm from the 0.3cm-0.5cm below the bud base. The xylem can be seen slightly on the long section, and the pith can be seen at the base , and then cut a 20-30-degree horse-ear-shaped short section on the back of the long section; select a common Camellia oleifera tree with a smooth surface, no pests and dis...

Abstract

The invention discloses a tree grafting method for Camellia liberofilamenta Chang et C.H.Yang. The method comprises following steps: scion selection, scion processing, stock selection, stock processing, stock cutting and bark pulling, scion inserting, binding, moisture retention and management after grafting. According to the invention, mature effect of in large individual trees can be fully utilized to realize early flowering and fruiting of survived grafted plants. And because rootstocks have a complete root system, enough water and nutrients are provided for scions. The growth and development of grafted plants are strong; the grafting interface of the stock close up fast and the survival rate of the tree grafting is high; consumed material for reproduction is less; the cost for cultivation is low; at the same time, the ornamental value of Camellia liberofilamenta Chang et C.H.Yang can be increased; large quantity of propagation material is stored for the propagation of Camellia liberofilamenta Chang et C.H.Yang.

Description

technical field [0001] The invention relates to the technical field of tree propagation, in particular to a method for grafting large trees of Camellia japonica. Background technique [0002] Camellia liberofilamenta Chang et C.H.Yang is a plant of the Camellia genus Camellia, with golden yellow flowers and large and slightly fragrant flowers. It is the only plant in the Camellia group distributed in Guizhou, and only 13 plants have been found in the wild. This species is also one of the species distributed in the northern edge of the Camellia japonica group. With the special ornamental, economic and medicinal value of Camellia japonica increasing day by day, its market development and utilization are very active in recent years, and the seedling resources are also in short supply, which greatly affects the development and application prospects of Camellia japonica. At present, the methods for asexual propagation of Camellia officinale mainly use cuttings and grafting of bu...
