Problems solved by technology

[0003] In recent years, tiger tongue red as a newly developed germplasm resource of fine wild flowers has achieved initial results, but there are still many problems in realizing the industrialization and large-scale production of tiger tongue red. During the grafting process, the disease of grafted seedlings leads to a decrease in the survival rate of grafting The slow rooting speed of grafted seedlings is one of the more prominent problems
During the grafting process, soil is often used as the substrate and organic fertilizers are added at the same time. However, if the soil or fertilizer is not thoroughly sterilized, it will carry a variety of germs. The germs invade through the grafting interface, causing the grafting interface to rot and cause grafting failure.
At present, there is also a grafting method using traditional peat, vermiculite, and perlite as the matrix mixed with organic fertilizers, but because the matrix has not been optimized, the growth of the grafted tiger tongue is not ideal, and the rooting time is long, which cannot meet the cultivation requirements. The EC value (soluble ion concentration) after mixing the fertilizer and the substrate is relatively high, which can easily inhibit the growth of tiger tongue, and more seriously, it may cause salt damage and burn the leaves. After soaking the substrate in water, the EC value may be too low. Insufficient to maintain the normal growth of Tiger Tongue Red, resulting in graft failure, so the method of soaking in water cannot adjust the EC value of the substrate

Embodiment 1

[0046] Before carrying out the tiger tongue red grafting seedling raising of the present invention, need to prepare culture substrate earlier, the preparation method of culture substrate is as follows:

[0047] First prepare the mangosteen fiber:

[0048] (1) 5kg of fresh mangosteen shells are pulverized and mixed evenly with 60wt% sorbitol solution, the sorbitol solution is just not over the mangosteen shells, then adding hydrochloric acid solution to adjust the mixed solution pH of mangosteen shells and sorbitol After 2.5, add 1kg of 2wt% gelatin solution, stir evenly, and heat in a water bath until a gel is formed;

[0049] (2) Crush the gel, ferment in a cool place at 26±1°C for 3 days, then add deionized water to cover the gel, then heat until the gel is completely melted, add 0.5kg of ammonium oxalate, stir evenly, and filter. get crude fiber;

[0050] (3) The crude fiber and the hydrochloric acid solution with pH=2.0 are mixed according to the ratio of 1:0.1 by weight...

Embodiment 2

[0066] Before carrying out the tiger tongue red grafting seedling raising of embodiment 2, need to prepare culture substrate earlier, the preparation method of culture substrate is as follows:

[0067] First prepare the mangosteen fiber:

[0068] (1) 10kg of fresh mangosteen shells are pulverized and mixed evenly with 65wt% sorbitol solution, the sorbitol solution just does not cross the mangosteen shells, then add hydrochloric acid solution to adjust the pH of the mixed solution of mangosteen shells and sorbitol: After 3, add 2kg 2wt% gelatin solution, stir well and then heat in a water bath to form a gel;

[0069] (2) Crush the gel, ferment in a cool place at 26±1°C for 2 days, then add deionized water to cover the gel, then heat until the gel is completely melted, add 1 kg of ammonium oxalate, stir evenly, and filter to obtain crude fiber;

[0070] (3) The crude fiber and the hydrochloric acid solution with pH=3.0 are mixed according to the ratio of 1:0.1 by weight and st...

Embodiment 3

[0086] Before carrying out the tiger tongue red grafting seedling raising of embodiment 3, need to prepare culture substrate earlier, the preparation method of culture substrate is as follows:

[0087] First prepare the mangosteen fiber:

[0088] (1) 8kg of fresh mangosteen shells are pulverized and mixed evenly with 62wt% sorbitol solution, the sorbitol solution just has not crossed the mangosteen shells, then add hydrochloric acid solution to adjust the mixed solution pH of mangosteen shells and sorbitol After 2.5, add 1.6kg of 2wt% gelatin solution, stir well and then heat in a water bath until a gel is formed;

[0089] (2) Crush the gel, ferment in a cool place at 26±1°C for 3 days, then add deionized water to cover the gel, then heat until the gel is completely melted, add 0.8kg of ammonium oxalate, stir evenly, and filter. get crude fiber;

[0090] (3) The crude fiber and the hydrochloric acid solution with pH=2.5 are mixed according to the ratio of 1:0.1 by weight and...

Abstract

The invention discloses a grafting and seedling raising method for Ardisia mamillata Hance, and belongs to the technical field of seedling grafting. The grafting and seedling raising steps comprise rootstock selection, scion selection, scion cutting, rootstock cutting, scion cutting and binding, and post-grafting management, wherein in the post-grafting management step, the EC value of a culture medium adopted by a seedbed is 0.8-1.2 ms / cm. According to the method, grafting is carried out by utilizing twigs and tender shoots of the Ardisia mamillata Hance, excellent characters of a Ardisia mamillata Hance scion variety are kept; and meanwhile, a grafting culture medium is treated, the EC value is adjusted, meanwhile, the fertility of the medium is improved, the culture period is shortened,the disease probability of grafted seedlings is reduced, the grafting survival rate is increased, and the ornamental value of Ardisia mamillata Hance plants is improved.

Description

technical field [0001] The invention relates to the technical field of seedling grafting, in particular to a method for grafting and growing seedlings of tiger tongue red. Background technique [0002] Tiger tongue red (Ardisia mamillata Hance), also known as tiger tongue, red-haired horse tire, red carpet, red felt, is a perennial evergreen shrub of the genus Ardisia mamillata Hance, and is a rare wild ornamental plant. Its leaves are ruddy, oval-shaped and hairy, so named after they resemble a tiger’s tongue. The red-purple hairs reflect the colorful Buddha’s light in the sun, so it is also called Buddha’s light red. It brings a symbol of joy to people. Hutonghong has a beautiful plant shape, which can be used for viewing leaves and fruits. The fruit color is red and shiny, and looks like a pearl. It symbolizes that the fruit and leaves form an interesting contrast, like a tiger tongue sweet pearl, which is of great ornamental value. It is not only widely used in landscap...
