Problems solved by technology

However, the grafting of these two kinds of plants is interspecific distant grafting, and the differences in physiological structure and genetic factors between plants of different species in the same genus lead to low plant tissue affinity, slow wound healing between tissues, and low graft survival rate. , high difficulty in grafting

Embodiment 1

[0069] 1. Preparation of rootstock and scion materials

[0070] In the same period, sow vermilion seeds and a bunch of red seeds in different hole trays, and cover the surface of the substrate with vermiculite, in which peat and sand are mixed at a volume ratio of 1:1 as the cultivation substrate, and then cover the holes with plastic film Moisturize the tray; change the pot when there are 2 to 3 pairs of true leaves (the purpose is to promote the growth of the root system, which can better promote the overall growth of the plant), and pay attention to water and fertilizer management (water the 'Christmas tree' dissolved in a ratio of 1:1000 once a week Water-soluble compound fertilizer), grafting will be carried out when Zhulip and Yichuanhong change pots to 5-6 pairs of true leaves.

[0071] After changing the pot, Zhulip can be used as a rootstock for grafting when it grows to 5-6 pairs of true leaves, because after removing the top 2 nodes, 3-4 nodes can be left as rootsto...

Embodiment 2

[0091] 1. Preparation of rootstock and scion materials

[0092] Same as Example 1.

[0093] 2. Preparation of rootstock material

[0094] Except that step 2A) retains the bottom 4 joints of the stem section of the vermilion lip plant as rootstock, all the other are the same as in Example 1.

[0095] 3. Preparation of scion materials

[0096]3A, select seedling stage, have a bunch of red strong plants of 5~6 pairs of true leaves, cut and keep the top tender stems of 3 nodes, and the distance from the functional leaves of the 3rd nodes is the top tender stems of 2.5cm as the scion, Then cut and remove part of the functional leaves, the area of ​​the retained functional leaves is 1 / 2 (usually 1 / 3 to 2 / 3, preferably 1 / 2) of the original functional area, that is, to cut and remove half of the functional leaves. That is to cut off half of the functional leaf area;

[0097] 3B, cut the stem portion into a wedge-shaped length of 1.0cm at the bottom 1.5cm place of the bottom pair o...

Embodiment 3

[0104] 1. Preparation of rootstock and scion materials

[0105] Same as Example 1.

[0106] 2. Preparation of rootstock material

[0107] Except that step 2A) retains the bottom 3 joints of the stem section of the vermilion lip plant as a stock, and splits the stock stem section upper end vertically, except that the depth is 0.7cm, all the other are the same as in Example 1.

[0108] 3. Preparation of scion materials

[0109] 3A, select seedling stage, have 5~6 pairs of true leaves of a bunch of red robust plants, cut and keep the top tender stems of 2 nodes, and the top tender stems with a distance of 2.0cm from the functional leaves of the second node are used as scions, Then cut and remove part of the functional leaves, the area of ​​the retained functional leaves is 1 / 2 (usually 1 / 3 to 2 / 3, preferably 1 / 2) of the original functional area, that is, to cut and remove half of the functional leaves. That is to cut off half of the functional leaf area;

[0110] 3B, cut the ...

Abstract

The invention discloses a grafting method of a flower plant salvia splendens. The method comprises the following steps: taking a salvia splendens plant at a seedling stage as a scion and grafting thescion on a salvia coccinea plant at the seedling stage. The grafting method of the flower plant salvia splendens, disclosed by the invention, is used for distant grafting of salvia plants; the growthvigor and resistance of the scion are improved by utilizing high-quality stocks and the distant hybridization affinity between a grafted seedling and a salvia coccinea interspecific plant is enhanced;the fructification rate of hybridization is improved.

Description

technical field [0001] The invention belongs to the technical field of interspecies grafting of ornamental plants, and relates to a method for grafting flowers and plants of the same genus and different species, in particular to a method for grafting a string of red flowers and vermilion lips. Background technique [0002] Grafting is an ancient plant asexual reproduction technology, a kind of vegetative reproduction in asexual reproduction, and an ancient method of artificially propagating plants. The commonly used grafting methods of grafting mainly include branch grafting and bud grafting, of which branch grafting is divided into cut grafting and split grafting. [0003] Grafting is carried out by taking advantage of the healing function of plants after injury, that is, grafting the branches or buds of one plant to the stem or root of another plant, so that the two parts that are joined together grow into a complete plant. . When grafting, the scion should be closely co...
