Problems solved by technology

[0003] Under natural conditions, although the distribution of the body odor is wide, it is not concentrated, the population is small, the flowering and fruiting are few, and the seeds are difficult to germinate, which leads to the increasing scarcity of its wild resources.

Embodiment 1

[0017] Embodiment 1: the screening of cutting material and cutting time,

[0018] Plant material body odor wood in the present invention ( Premna puberula Pamp.) is collected from Wuchuan Gelao and Miao Autonomous County, Guizhou Province, and cultivated under three conditions: heavy shading (light transmittance 8%-10%), moderate shading (light transmittance 20%-25%) and natural light .

[0019] During the bud dormancy period (early December to mid-January), germination period (late January to late February) and leaf-expansion period (early March to late April), the annuals grown under the above three light conditions were harvested. Cuttings are carried out on strong branches without pests and diseases and without mechanical damage. The cuttings were cut to a length of 20-25 cm, the top was cut flat at a distance of 1-2 cm from the node, and the base was obliquely cut. Each cutting contained 2-3 nodes, and the survival rate was counted. Conclusion: The cuttings of C. bodh...

Embodiment 2

[0021] Embodiment 2: the screening of plant growth regulating substance,

[0022] Cut cuttings with basically the same growth conditions (the cutting method is the same as in Example 1), and place the cuttings in concentrations of 50, 100, 200, and 400 mg·L -1 The cuttings were soaked in 6-BA, KT, NAA, and IBA solutions for 2 h, and the survival rate was counted with clean water as the control. Conclusion: In 6-BA 200 mg·L -1 , 6-BA 400 mg·L -1 and NAA 200 mg·L -1 The cuttings of C. chinensis soaked in the solution have a higher survival rate of the cuttings (Table 2).

[0023]

Embodiment 3

[0024] Embodiment 3: the optimization of cutting condition,

[0025] During the dormancy period of buds, the branches of C. chinensis under moderate shading conditions were cut, and a three-factor three-level orthogonal experiment was designed with different concentrations of 6-BA, NAA and soaking time. After treatment, the cuttings were cut, and the survival rate was counted. Conclusion: The cuttings were treated with 6-BA 300 mg·L -1 +NAA 200 mg·L -1 After soaking in the solution for 1 h, the cutting survival rate was higher (Table 3).

Abstract

The invention discloses a premna puberula cutting propagation method. The method includes the steps that a premna puberula annual branch growing under the moderate shading condition is cut in the bud dormancy period to serve as a cutting material, a trimmed cutting shoot is soaked with a solution of 6-BA 300 mg.L<1>+NAA 200 mg.L<1> for cutting, the cutting shoot is transplanted after surviving, and a newborn plant can be obtained. The proliferation problem of seedlings of premna puberula in the large-scale artificial planting is effectively solved, and a good foundation is laid for achieving sustainable use of resources and industrialized development.

Description

technical field [0001] The invention relates to a method for asexual propagation of plants, in particular to a method for cutting and propagating Chai bodhisattva. Background technique [0002] body odor chai ( Premna puberula Pamp.), also known as Shenxian Doufuchai, Turtledove, etc., belongs to the Verbenaceae Doufuchai genus perennial deciduous shrubs, mainly distributed in Guizhou, Gansu, southern Shaanxi, Hubei, Hunan, Sichuan and Yunnan in my country, growing at an altitude of 700 ~1800 m hillside jungle, it is a kind of medicinal and edible plant. The roots, stems and leaves of body odor Chai can be used as medicine, which has the functions of clearing heat and dampness, detoxifying and reducing swelling, regulating menstruation and strengthening yang. The leaves of Hubuchai are rich in pectin, sugars, proteins, amino acids, vitamins and mineral elements. The "immortal tofu" made of it is green in color, delicious in taste, and can clear away heat and cool off. It ...
