Embodiment 1

[0022] A kind of propagation method of ancient tea tree, comprises the following steps:

[0023] (1) In March 2014, the branches of ancient tea trees in Dachagou, Xinyang were topped, and 50% gibberellin was sprayed on the branches for 3 days;

[0024] (2) Collect semi-lignified branches, cut them into 1000 short branches with leaves of 3 cm, leave axillary buds, and the upper and lower cuts are smooth. The solution is dipped in the cut of the lower end of the branch, then the cuttings are placed in a soilless substrate and cultivated for 20 days in a natural environment. The soilless substrate includes the following raw materials in percentage by weight: peat 62%, vermiculite 35% and superphosphate 3% , the content of organic matter in the matrix is ​​15%, the content of total nitrogen is 0.3%, the content of total phosphorus is 0.2%, the content of total potassium is 0.5%, and the pH value of the matrix is ​​5.0;

[0025] (3) Transplant the branches of step (2) into a cultu...

Embodiment 2

[0028] A kind of propagation method of ancient tea tree, comprises the following steps:

[0029] (1) In March 2014, the branches of ancient tea trees in Dachagou, Xinyang were topped, and 50% gibberellin was sprayed on the branches for 2 days;

[0030] (2) Collect semi-lignified branches and cut them into 1,000 short branches with leaves of 4 cm. The upper and lower cuts are smooth, and the cuts at the lower ends of the branches are parallel to the growth direction of the leaves. Cuttage is then cultivated in a soilless substrate for 25 days in a natural environment. The soilless substrate includes the raw materials of the following weight percentages: peat 65%, vermiculite 32% and superphosphate 3%, and the organic matter content in the substrate is 17%, total nitrogen content 0.35%, total phosphorus content 0.28%, total potassium content 0.6%, matrix pH value 4.5;

[0031] (3) Step (2) branch cuttings are housed in the cultivation bag of nutrient soil, and described nutrien...

Embodiment 3

[0034] A kind of propagation method of ancient tea tree, comprises the following steps:

[0035] (1) In September 2014, the branches of ancient tea trees in Dachagou, Xinyang were topped, and 50% gibberellin was sprayed on the branches for 3 days;

[0036] (2) Collect semi-lignified branches and cut them into 1000 short branches with leaves of 5cm. Then the cuttings were placed in the soilless substrate and cultivated in the natural environment for 30 days. The soilless substrate included the raw materials in the following percentages by weight: peat 70%, vermiculite 27% and superphosphate 3%, and the organic matter content in the substrate was 18%, total nitrogen content 0.4%, total phosphorus content 0.35%, total potassium content 0.65%, matrix pH value 6.0;

[0037] (3) Transplant the branches of step (2) into a culture bag equipped with nutrient soil. The nutrient soil includes the following raw materials in weight percentage: 55% garden soil, 22% yellow heart soil, 10% n...

Abstract

The invention belongs to the technical field of breeding and particularly relates to an ancient tea tree breeding method. The ancient tea tree breeding method includes the following steps that ancient tea tree branches are topped, crotch positions are sprayed with 50% gibberellin for 2-5 days; then semi-lignified branches are acquired and sheared into 3-5 cm short branches with leaves, axillary buds are retained, lower-end cuts of the branches are treated by using a growth hormone solution, then the branches are cut into a soil-less substrate and are cultured in a natural environment for 20-30 days; then, the branches are transplanted in culture bags containing nutritional soil, are cultured in the natural environment for 20-30 days and are watered with nutritional soil surface whitening as the standard, wherein the watering amount making the nutritional soil in a wet state is appropriate; when new roots grow out of above 70% of the branches, transplantation is performed. The ancient tea tree breeding method is simple in operation, low in cost, high in survival rate, short in breeding period and easy to popularize and apply.

Description

technical field [0001] The invention belongs to the technical field of propagation, and in particular relates to a propagation method of ancient tea trees. Background technique [0002] Ancient tea trees refer to old trees that have grown for more than a hundred years and have a certain cultural background. They are the birthday stars of the tea tree family. In recent years, the ancient tea trees in Dachagou on the north side of Jigong Mountain in Xinyang have attracted more and more attention from the society. The ancient tea trees in Dachagou were planted in the late Ming Dynasty, between 1500 and 1600, and the trees were 400-500 years old. The content of free amino acid in its tea soup is 0.9%, the content of tea polyphenols is 12.4%, the content of caffeine is 0.3%, the content of soluble sugar is 14.7%, and the content of water extract is 48.2%. heritage and cultural heritage. However, the ancient tea trees in Dachagou are difficult to reproduce, the survival rate of ...
