Problems solved by technology

The long-term excavation has led to a decrease in the distribution area of ​​Smilax smilax, and the wild resources and ecological environment have been seriously damaged.
In order to meet the raw material supply of Smilax smilax tubers and the protection of the natural environment, vigorously developing the artificial propagation of Smilax smilax has become an urgent problem to be solved, but there is no artificial propagation method of Smilax smilax in the prior art. related research reports

Embodiment 1

[0018] Cuttings began in November. Prepare the seedbed in advance, the seedbed soil layer is 15 cm, the upper soil layer is humus soil, the lower soil layer is clay, and water before cutting. Select 100 branches of Smilax smilax with a diameter of 4 mm and well-developed more than 5 years old, cut them into 12 cm long, keep an axillary bud between the upper and lower incisions, and seal the upper and lower incisions with mud. Then the cuttings were placed in the pre-moistened seedbed according to the row spacing of 20 cm × 10 cm, the cutting depth was 7 cm, and the cuttings were covered with weeds for shade, and the survival rate reached 63%.

Embodiment 2

[0020] Cuttings began in November. Prepare the seedbed in advance, the soil layer of the seedbed is 18 cm, the upper soil layer is humus soil, the lower soil layer is clay, and water before cutting. Select 100 short-column Smilax smilax branches with a diameter of 6 mm that have been well developed for more than 5 years, cut them into 15 cm long, keep two axillary buds between the upper and lower incisions, and seal the upper and lower incisions with mud. Then the cuttings were placed in the pre-moistened seedbed according to the row spacing of 20 cm × 10 cm, the cutting depth was 8 cm, and the cuttings were covered with weeds for shade, and the survival rate reached 68%.

Embodiment 3

[0022] Cuttings began in November. Prepare the seedbed in advance, the seedbed soil layer is 20 cm, the upper soil layer is humus soil, the lower soil layer is clay, and water before cutting. Select 100 branches of Smilax smilax with a diameter of 8 mm and well-developed more than 5 years old, cut them into 12 cm long, keep an axillary bud between the upper and lower incisions, and seal the upper and lower incisions with wax cement slurry. Then the cuttings were placed in the pre-moistened seedbed according to the row spacing of 20 cm × 10 cm, the cutting depth was 7 cm, and the cuttings were covered with weeds for shade, and the survival rate reached 60%.

Abstract

The invention discloses an artificial cutting propagation method of heterosmilax yunnanensis. According to the method, stems are cut from the upper portions of branches of the heterosmilax yunnanensis in autumn, wherein the diameter of each stem ranges from 4mm to 8mm, and the length of each stem ranges from 12cm to 15cm; one or two axillary buds are kept between the upper incision and the lower incision of each stem; the incisions are sealed by slurry or wax liquid; processed stems are planted into a seedbed in a cutting mode and are covered by weeds so that the sun can be blocked and soil moisture can be preserved. The cutting propagation method is easy and convenient to operate and low in cost, the survival rate of the stems reaches more than 60% after cutting is conducted, a large number of nursery-grown plants can be conveniently obtained, and resources are protected as well.

Description

technical field [0001] The invention belongs to the technical field of plant cultivation, and relates to plant asexual propagation technology, in particular to an artificial cutting propagation method of the medicinal plant Smilax smilax. Background technique [0002] Smilax sarsaparilla ( Heterosmilax yunnanensis Gagn.) is distributed in Hubei, Guangxi, Chongqing, Sichuan, Guizhou, and Yunnan. Liliaceae Smilax is a climbing shrub, glabrous; branchlets have obvious edges. Leaves papery or nearly leathery, ovate, ovate-cordate or ovate-lanceolate, 6-16 cm long, 4.5-15 cm wide, apex triangular-shaped short acuminate, base cordate or nearly round, main Veins 5-7, raised below, branches reticular, conspicuous on both sides; petiole 1.5-4 cm long, with tendrils and narrow sheaths at 1 / 3-1 / 7. Umbels with 20-60 flowers; total pedicel length (0.5-)1.5-2.5cm; inflorescences globose; pedicel length 1.2-2.5cm; male flowers: perianth tube elliptic, 5-9mm long, 3- 4 mm, with 3 cogs ...
