Embodiment Construction

[0022] refer to figure 1 , which shows a cutting propagation method of Vernonia amygdala provided by the embodiment of the present invention, comprising the following steps:

[0023] S1. Seedbed selection: In the greenhouse, choose a flat concrete floor or a layer of pebbles as the seedbed. In the prior art, the land is used as the seedbed, and the land needs to be arranged and sterilized during the cutting process, so that the growth of the seedlings will not be affected. Using a flat cement floor or a layer of pebbles as a seedbed can omit the steps of finishing and disinfection, saving labor and time for the cutting process.

[0024] S2. Prepare a plant growth regulator: use IBA to prepare a plant growth regulator with a concentration of 1 mg / L-10 mg / L.

[0025] IBA is indole butyric acid, the pure product is a white crystalline solid, and the original drug is a white to light yellow crystal. Soluble in organic solvents such as acetone, ether and ethanol, hardly soluble ...

Abstract

The invention discloses a cutting propagation method of vernonia amygdalina. The method comprises the following steps: S1, selecting a seed bed; S2, preparing a plant growth regulator; S3, treating a cutting medium; S4, preparing cuttings; S5, carrying out cuttage; S6, carrying out tending management. After the steps are carried out, the cutting propagation method of the vernonia amygdalina, shown by the embodiment of the invention, enables cutting propagation survival rate to reach 100%, shortens the rooting time to 5-7 days, and greatly increases propagation coefficient; the method is simpler to operate and easy to implement, and reduces the cost; after the method is used, seedlings come out evenly and attractively, and a great deal of high-quality tidy nursery stocks can be provided for afforestation farmers within a short time.

Description

technical field [0001] The invention relates to the technical field of cutting propagation, in particular to a cutting propagation method of Vernonia amygdala. Background technique [0002] Vernonia amygdala is a plant of the genus Vernonia in the Asteraceae family, a perennial tree or shrub, native to tropical Africa, and is a traditional African folk herbal medicine. Its leaves are rich in antioxidants. In the place of origin, people use its leaves as vegetables, and for repelling worms, treating fever, gastrointestinal diseases, etc.; in Southeast Asia and Taiwan, it is widely used as an anti-cancer herbal medicine; almond dove The research on the chemical constituents of chrysanthemum began in the late 1960s, and its anti-cancer reports began to appear in 1969. Afterwards, scholars from many countries have found that the extract of Vernonia almonds leaves has antithrombotic, antibacterial, and inhibitory cancer cell synthesis, etc. It also has certain effects on wind-he...
