Problems solved by technology

However, camellia germplasm has large and colorful flowers and is loved by people. The progress of resource development and utilization is slow, and the commercialization of germplasm resources is seldom, mainly limited by the constraints of reproductive technology.
Grafting is a common method for asexual reproduction of camellias. The commonly used grafting method has defects such as water accumulation at the interface, unstable survival rate, limited grafting height and grafting season, and restricted grafting site.

Embodiment 1

[0031] Example 1: Grafting location: Palm Camellia Base in Gaoyao District, Zhaoqing City, Guangdong Province, grafting varieties "Xia Yong Guo Se" and "Xia Meng Wen Qing".

[0032] a. In March 2016, select robust Gaozhou camellia oleifera sparse forest seedlings with a diameter of 3 to 4 cm as the rootstock 1, and process the rootstock 1: pruning, and keep 1 to 2 branches below the height of 25 cm from the ground; the height of the height from the ground is about 25 cm, Cut the upper part obliquely horizontally, the incision is slightly inclined, and the height difference of the incision is not more than 0.5cm; open on one side, cut a 1-2cm long incision 2 from top to bottom at the high end of the incision, and the depth of incision 2 is slightly greater than the diameter of the scion by 0.1-0.2cm.

[0033] b. Select the robust, pest-free, and full-bud branches of the camellia varieties "Xia Yong Guo Se" and "Xia Meng Wen Qing" to be pruned as scions. Each scion only contains ...

Embodiment 2

[0039] Example 2: The grafting location is Hongfa Huamuchang, Zhaoqing City, Guangdong Province, and the grafted varieties "Xiamengyanping" and "Xiafengrelang".

[0040] It is basically the same as Example 1, except that the time of grafting is July 2016. In step a, Gaozhou Camellia oleifera bag seedlings with a diameter of 1 to 2 cm are selected as rootstocks. The grafting height is 10 cm from the ground, and the grafting site is a simple shade greenhouse.

[0041] The grafting survival rates of the camellia varieties "Xiamengyanping" and "Xiafengrelang" in Example 2 are shown in Table 2:

[0042] Table 2:

[0043] Variety

Embodiment 3

[0044] Example 3: The grafting site camellia base of Zhaoqing Agricultural University Horticultural Farm, Deqing City, Guangdong Province, grafted varieties "Xiamenghualin" and "Xiari Qixin".

[0045] It is basically the same as Example 1, except that the grafting time is November 2016, and in step a, Gaozhou Camellia oleifera seedlings with a diameter of 5-6 cm are selected as rootstocks, the grafting height is 50 cm from the ground, and the grafting site is open air.

[0046] The graft survival rates of the camellia varieties "Xiamenghualin" and "Xiari Qixin" in Example 3 are shown in Table 3:

[0047] table 3:

[0048] Variety

[0049] From Examples 1, 2 and 3, it can be seen that the grafting survival rate of the present invention is high, the grafting season and grafting height can be freely selected, not limited by the site, and has strong practicability, which is worth popularizing.

Abstract

The invention discloses a single-bud whole-leaf turnup dewatering grafting method for camellia. The single-bud whole-leaf turnup dewatering grafting method comprises the following steps: by taking oil-tea camellia as stock, trimming branches and leaves below a grafting height, retaining 1 to 2 branches, slantways cutting off the upper part at the determined grafting height, and forming an opening in a single side of the top or longitudinally splitting the top to form an opening; cutting one end of a scion, which only comprises a bud and a whole leaf, into a symmetric wedge shape with two flat surfaces, inserting the scion into the incision, and twining a grafting port tightly with a grafting film; naturally turning up the leaf of the scion to enable the leaf to be wound on the branch of the stock, twining the leaf with the grafting film, keeping 0.5 to 1 cm of the lower part of the turned leaf not wrapped for dewatering, and wrapping the other parts of the leaf and the bud into the grafting film; after the bud is germinated, forming a callus between the scion and the incision, cutting off the branch and the leaf which are left below the grafting port, and picking the bud. According to the single-bud whole-leaf turnup dewatering grafting method for the camellia, the problem of water accumulation of the grafting port is solved; the survival rate is high; and the camellia grafting method, in which the grafting height, a grafting season and a grafting site can be freely selected, is realized.

Description

【Technical field】 [0001] The invention relates to a single-bud whole-leaf rolling hydrophobic grafting method of camellia, belonging to the technical field of plant cultivation methods. 【Background technique】 [0002] Camellia is a traditional famous flower in my country, because of its green and green leaves. In recent years, domestic camellia varieties have been continuously introduced, and the emergence of new varieties of multi-season camellias indicates that my country's camellia breeding has reached the international leading level. However, camellia germplasm has large and colorful flowers and is popular with people. The development and utilization of resources is slow, and the commercialization of germplasm resources is seldom, mainly restricted by the constraints of reproduction technology. Grafting is a common method for asexual reproduction of camellias. Commonly used grafting methods have disadvantages such as water accumulation at the interface, unstable surviva...
