Problems solved by technology

Some plants are easy to carry out asexual reproduction, while some plants cannot carry out asexual reproduction at all; some plants have large differences in C / N and hormone content or ratio in different growth stages, and need to carry out asexual reproduction in a specific period; some plants Then because it contains certain substances (for example, coniferous plants are difficult to reproduce asexually because they contain turpentine) to inhibit the occurrence of roots or buds, they cannot reproduce asexually

Embodiment 1

[0042] Embodiment 1 The in situ layering propagation of Ceratia genus plants

[0043] On August 1, 2013, several seedlings of C. gigantea (C. Gigantea) with a height of 10 to 20 cm from the planting base of Teng County, Guangxi and C. Procera with white flowers (C. Procera) from Guangxi Medicinal Botanical Garden were propagated. Transplanted in the experimental practice farm of Guangxi University (Nanning) as their respective mother plants to be multiplied; at the end of October, the in-situ layering propagation of the genus Ceratia was carried out in Guangxi University, and the main stem with a growth height of 60-80cm was topped to germinate axillary buds. After 1 week, directly press the above-mentioned main stem after topping into the soil around the mother plant to be multiplied (the ditch depth is 4-10 cm), and its tip is 10-20 cm (there is a little difference between the plants, so that each branch is exposed) The length of the tip can be within this range, the same b...

Embodiment 2

[0045] Embodiment 2 The in vitro layering propagation of Ceratia genus plant 1

[0046] The seed propagation seedling used in Example 1 was used as the mother plant to be multiplied. In October 2013, the in vitro layering propagation of Ceratia genus plants was carried out at the same time as in Example 1 at Guangxi University.

[0047] Select the main stem or side branch with no pests and diseases and good filling degree (the external shape judgment standard of the main stem or side branch with good filling degree is: the part below the point where the hairs on the stalk begin to fall off), and remove the top 5 ~ 8 days before layering. 7cm (there is a little difference between plants, just ensure that the length of the top of each branch removed is within this range); when layering, cut off from the base of the branch, place it in the layering ditch (ditch depth 4-10cm), cover it with soil, and place it The 10-20m of the tip is exposed to the outside of the soil, compacted, ...

Embodiment 3

[0049] Embodiment 3 Ceratia plant in vitro layering propagation 2

[0050] The seed propagation seedling used in Example 1 was used as the mother plant to be multiplied. In October 2013, the in vitro layering propagation of Ceratia genus plants was carried out at the same time as in Example 1 at Guangxi University.

[0051] Select the branches of Ceratia genus plants that are not well-filled enough to be multiplied on the mother plant, spray paclobutrazol (spray according to the concentration in the instructions) 2 weeks before layering to make the branches full, and remove 5-7 cm from the top of the stem 10 days before layering; when layering, Cut off from the base of the branch, place it in a beading ditch (ditch depth 4-10cm), cover with soil, and expose its tip 10-20cm to the outside of the soil, compact it, water it enough, and cover it with grass. A total of 50 branches of C.Gigantea and C.Procera were pressed together; in November 2013, the axillary buds were unearthed,...

Abstract

The invention provides a calotropis layering propagation method. Vegetative propagation is performed on calotropis with the layering propagation method. Layering is A in-situ layering or B in-vitro layering. The vegetative propagation is performed on the calotropis with the calotropis layering propagation method, the survival rate is up to 100%, the seed nature of the calotropis can be kept, character segregation can be avoided, the calotropis can bloom and fruit in advance, and the method is applicable to high-yield cultivation of the calotropis and breeding of clonal varieties and has the very broad industrial application prospect.

Description

technical field [0001] The invention belongs to the technical field of planting, and in particular relates to a method for asexual propagation of plants, and more specifically, the invention relates to a method for layering propagation of plants of the genus Ceratia genus. Background technique [0002] Crow's horn melon, also known as heartbroken grass and five dogs lying flower, belongs to the perennial evergreen plant of Asclepiaceae. It is one of the mountain cotton plants and is distributed in the tropics and subtropics. Calotropis (Calotropis) has two species: C. Gigantea and white-flowered Gigantea (also known as big C. Procera, Latin name: C. Procera). The horned melon has a wide range of uses. Its seed wool is a new natural fiber substitute raw material. It can be planted in wastelands such as rocky desertification, saline-alkali land, and sandy beaches. It can expand the planting area of ​​textile raw materials and alleviate the contradiction between cotton and grai...
