Problems solved by technology

[0004] Due to the phenomenon of hollow pith core in Jujube vine, its cutting propagation is extremely difficult to survive. Therefore, exploring the vegetative propagation technology of Jujube vine, such as propagation through cuttings, has become an urgent problem to be solved for the population expansion of Jujube vine

Embodiment 1

[0020] (1) Seedbed selection, treatment and disinfection: choose a flat, dry, and shady place that is easy to drain as the seedbed, remove weeds and level the seedbed, and lay a layer of red bricks on the ground to make the seedbed 6cm above the ground ( The thickness of the red brick) to ensure good water permeability; the seedbed is inlaid with wooden planks around the seedbed, the thickness of the plank is 2cm, the height is at least 20cm, and the depth of burial is not less than 5cm; the concentration of 0.5wt% high Potassium manganate solution is disinfected;

[0021] (2) Nutrition bag preparation: the soil is dug deep below 2m below the surface to ensure the sterility of the soil; after the soil is retrieved, put them into nutrition bags with a diameter of 10cm. The 1cm of the nutrition bag shall prevail; after the nutrition bags are packed, they shall be placed in the seedbed in order, 10 bags shall be placed in a row, every 3 rows shall be in a group, and a 30cm width ...

Abstract

The invention provides a cutting propagation method for eleutharrhena macrocarpa. The method comprises the steps of seed bed land selection, processing and disinfection; preparation of nutrient bags; collection and treatment of cuttings; cutting; heat preservation, moisture preservation and shading treatment; seedling management. By using the method, the survival rate of cutting can be maximized, vigorous growth of seedlings can be guaranteed, the growth quantity of seedlings can be maximized, and thus the population quantity of eleutharrhena macrocarpa can be increased. The method can effectively guarantee the survival rate of cutting and formation of eleutharrhena macrocarpa seedlings, thereby achieving the objective of population propagation. The cutting propagation technique provided by the invention is also suitable for cutting propagation processes of other species with similar biological characteristics and has the advantages of low cost, simple operation, easy mastering and high survival rate. The method is especially suitable for cutting propagation processes of plants like eleutharrhena macrocarpa.

Description

technical field [0001] The invention relates to a cutting propagation method of vine jujube, which belongs to the technical field of plant propagation. Background technique [0002] As a single-species genus of Fangjiaceae, the distribution of vine is intermittent and narrow, which has important research value in systematics and floristic geography. However, the wild population of Jujube vine is extremely rare. When the Red List of Species in China listed vine vine as a critically endangered species, only 1 vine was known. After a large-scale field investigation by scientific researchers, the reliable number of vine jujubes that can be seen so far is only about 50, and the risk of extinction is extremely serious. Therefore, vine jujube is listed as a wild plant under the national first-level key protection in my country (State Forestry Administration and Ministry of Agriculture, 1999), and critically endangered (CR-D ) species, and one of the 112 very small population prote...
