Embodiment 1

[0027] Embodiment 1 The method of the present invention

[0028] (1) Induction culture of Selaginella cuspidatum

[0029] The 3-year-old single plant (with roots) of wild Selaginella serrata was planted in a plastic flowerpot equipped with a mixed substrate for inducing culture of pearl buds, the inner diameter of the flowerpot was 15-16 cm, and the mixed substrate was composed of peat and perlite in a volume ratio= 10:1 mixed with 2kg / m added to the mixed matrix 3 The slow-release fertilizer, in terms of mass fraction, the slow-release fertilizer contains N14%, P 2 O 5 14%, K 2 O14% and S 4%. The flowerpots planted with the cushion-shaped selaginella plants are placed in a low-light greenhouse equipped with shading nets, supplementary lights and temperature control equipment. ~180μmol m -2 ·s -1 , the light intensity at noon on cloudy days and noon on rainy days is 40-60 μmol m -2 ·s -1 . Water every 4 days to keep the water content of the mixed substrate at 40-45%...

Embodiment 2

[0039] Embodiment 2 and embodiment 3 are methods of the present invention

[0040] Except for the different measures listed in Table 1, the other measures in Example 2 and Example 3 are the same as those in Example 1, and will not be repeated here.

[0041] Table 1 Differences between the steps of Example 2-Example 3 and Example 1

[0042]

[0043]

[0044] The reproductive effect of table 2 embodiment 1-3

[0045]

[0046] control

[0047] The control was the reproduction of the wild plants of Selaginella cuspidatum in the wild habitat.

[0048] (1) Observation objects: In the same growing area in the field, 30 2-3 year-old wild plants of Selaginella cuspidatum with the same growth pattern were selected as the observation group.

[0049] (2) Wild habitat: bare limestone surface, extremely thin soil layer; distinct dry season and rainy season, the average annual precipitation is about 600-800 mm, of which the dry season precipitation accounts for 10-12%; the noon l...

Abstract

The invention relates to a method for propagating the bulb buds of the revived plant Selaginella cuspidatum, which comprises the following steps: inducing and culturing the bulb buds of Selaginella cuspidatum, cultivating the bulb buds on a plug tray, colonizing the bulb bud plug seedlings, and managing the cultivation after the colonisation. The invention successfully uses 2-3-year-old plants of wild Selaginella as the material, and through the control of the cultivation substrate, light conditions and water conditions, after 5-6 months of bud induction and culture, the bud induction rate reaches 100%, and a single mature The average number of buds formed on the shoots was more than 20 buds. After colonization, the selaginella buds are domesticated and cultivated step by step in different cultivation environments such as weak light greenhouses, strong light greenhouses and open fields. The blank of artificial reproduction technology of cypress is of great significance to the protection of wild populations and the development and utilization of resources of the revived plant Selaginella cuspidatus.

Description

technical field [0001] The invention belongs to the field of plant propagation, and in particular relates to a bulbous bud propagation method for reviving plant Selaginella cuscus. Background technique [0002] Cushion Selaginella [Selaginella pulvinata (Hook. & Grev) Maxim.], belonging to Selaginella family (Selaginellaceae) Selaginella genus, is cushion-shaped, the main stem is not prostrate, mainly growing on exposed limestone surfaces or stone crevices, The growing environment is arid. Selaginella cuspidatum is commonly known as "Nine Dead Resurrection Grass". It is a typical recovery plant. It has strong dehydration resistance and can maintain long-term survival through low metabolism under extreme dehydration. When the moisture conditions are suitable, it can quickly return to normal. grow. Selaginella cuscus is a special kind of ornamental plant resource because of its miraculous resuscitation properties. At the same time, Selaginella cuspidatum contains flavonoids...
