Embodiment 1

[0028] (1) Cutting time: May in the first half of the year

[0029] (2) Cuttage fringe branch selection: cut stems from the selected excellent female parent tree with a stem thickness of 2 mm, new shoots that grow in the current year, branches that turn from green to red, semi-lignified, robust and free of quarantine diseases and insect pests, and have axillary buds Branch tips as cutting ears;

[0030] (3) Clipping of the cutting ear: select the cutting ear branch with a strong leaf supporting the axillary buds, cut off the branches at 5 mm above the leaves, cut off 1 / 2 of the leaves, and cut off the branches at 4 cm below the leaves. The stem is beveled downwards, and the cutting fringe branches at the beveled place are 40-45°;

[0031] (4) Preservation of cutting ears: the remaining cutting ears are piled up on the muddy ground with moisture, shade and wind, and sprinkled with a layer of water;

[0032] (5) Preparation of the seedbed: select an altitude of 1300 meters and...

Embodiment 2

[0041] The difference between the present embodiment and Example 1 is that the cutting time in the step (1) is November, and the pH value under the selected pine forest in the step (5) is 6 soils, and the plant spacing is 7cm in the step (6). In the step (7), the corn stalks are directly spread, and in May, the corn stalks are replaced with 3 layers of sunshade nets.

[0042] Adopt respectively traditional tea tree cutting seedling raising method and adopt the method of the present invention, carry out cutting seedling raising to 100 cutting ears, compare by the mode of experiment, and list relevant survival experiment data in the following table:

[0043] Unit (tree)

[0044] As can be seen from the above table, the cutting fringes that adopt the traditional tea tree cutting seedling raising method to cut the cuttings, the survival number in the first month is only 73, which is lower than the survival number using the method of the present invention, and the second m...

Abstract

The invention belongs to the field of tea tree seedling raising and specifically discloses a wild tea camellias cutting seedling raising method. The wild tea camellias cutting seedling raising method mainly comprises the following steps: within cutting time in May to June or October to November, scissoring new twigs which are 1.8-2.2mm in stem diameter and grown in the current year from selected excellent stock trees as cutting seedlings, wherein the branches become red from green, and the cutting seedlings are semi-lignified strong branch tips which are free of quarantine diseases and provided with axillary buds, preparing a seedling bed, cutting, shielding the sunshine, preventing freezing, performing field management after cutting, transplanting and the like. According to the characteristics that wild tea camellias is concentrated in a high altitude area with great diurnal temperature difference and cold winters, and has unique growth characteristics, improvements to the material selection, seedling bed preparation, seedling field management and the like, which are different from those of a common tea tree cutting technology, are made, so that the survival rate of the wild tea camellias is greatly increased.

Description

technical field [0001] The invention belongs to the field of tea tree seedling cultivation, in particular to a method for growing large tea tree seedlings by cutting. Background technique [0002] In my country's rich tea tree species resource bank, there is a type of large tea tree that is not artificially cultivated and rarely picked for tea, commonly known as wild large tea tree. This is a kind of arbor-type tea tree that is not artificially cultivated and is rarely used by people. Its common characteristics are tall trees, thick leaves, and leathery leaf surfaces. Most of the seeds are cone-shaped or kidney-shaped, with rough seed coat, strong resistance and low fecundity. The wild big tea tree is the primary tea tree germplasm resource with the richest genetic diversity and the most value for preservation and research. Since large tea trees are self-incompatible cross-pollinated plants, if the resources of wild large tea trees are not protected, the genetic resources ...
