Embodiment 1

[0023] (1) Seedling selection

[0024] Select seedlings from the 2-year-old Chinese tallow tree nursery to select two first-level branches on the same trunk and relatively straight stems. The diameter of the branches is 2 to 3 cm, and the selected seedlings are used as rootstocks use.

[0025] (2) Nursery selection

[0026] Choose a nursery with flat terrain and good drainage. The soil layer thickness is more than 50cm, the groundwater level does not exceed 1.5m, the pH value is 5.5-6.5, the soil is fertile, and the sandy loam soil with few pests and diseases.

[0027] (3) Seedling transportation

[0028] On December 20, 2017, the selected rootstock seedlings were pruned, and only two first-level branches were kept during pruning. The length of the branches kept was 20-30 cm, and wound healing agent was applied to the incision. After pruning, the seedlings are dug out from the original growth site. When digging the seedlings, the soil balls are round and have a diameter of...

Embodiment 2

[0036] Embodiment 2: no more details with embodiment 1, difference is: the quality of healing agent is composed as follows: sodium humate 5%, sodium alginate 4%, chitosan 2%, surplus is water; Scion is collected from Zhehuang No. 12 and Zhezi No. 10 (from Zhejiang Academy of Forestry Sciences).

Embodiment 3

[0037] Embodiment 3: the same place as in Example 1 will not be repeated, the difference is: the selection of seedlings is carried out from the 2-year-old Chinese tallow tree nursery, so as to select 3 first-level branches on the same main trunk, and the relatively straight Chinese tallow tree with a dry shape Seedlings; scions Zhehuang No. 12, Zhehong No. 8 and Zhezi No. 10 (from Zhejiang Academy of Forestry Sciences).

[0038] On November 12, 2018, the cultivation success rate of each embodiment was investigated, and the statistical results are shown in the table below.

[0039]

[0040] The survival of two or more scions grafted per plant is used as the standard for the successful cultivation of ornamental Chinese tallow tree seedlings with multicolored leaves. From the above table, it can be known that the success rate of cultivating ornamental Chinese tallow tree seedlings with multicolored leaves can reach more than 95%.

Abstract

The invention relates to a method for cultivating ornamental tallow tree seedlings with multicoloured leaves. The method includes the steps of seedling selection, garden field selection, lifting and transportation, seedling planting, grafting, garden field management and the like. According to the method, two or three primary branches of a common tallow tree are used as rootstocks, superior strains are used as scions, the characteristics of crown skeleton joints of the original tallow tree and high grafting survival rate are used, through grafting, good traits of different strains are organically combined, original autumn strains with the single leaf color are cultivated into the colorful tallow tree ornamental seedlings with various leaf colors in one, the ornamental value of original tallow tree seedlings and strains are greatly increased, the cultivating success rate can reach 95% or above, and meanwhile, operation is easy, so that extensive application and promotion are convenient.

Description

(1) Technical field [0001] The invention relates to a multi-color leaf ornamental Chinese tallow tree seedling cultivation method, which belongs to the technical field of native colored tree species seedling cultivation. (2) Background technology [0002] Chinese tallow tree Sapium sebiferum is a deciduous tree species of Euphorbiaceae Euphorbiaceae. It has strong adaptability, fast growth speed, and no strict requirements on soil. Can grow. Chinese tallow tree is a multi-purpose tree native to China. Because of its rich oil content, it has a very long history of cultivation as an oil tree species in China. At the same time, Chinese tallow tree has colorful leaves in autumn and has high ornamental value. It is a high-quality native colorful leaf tree species in subtropical regions. In the construction of garden landscape, Chinese tallow tree can be planted alone on the lakeside or lawn, matched with flower walls and rocks, and can also be used as a street tree in corridor...
