A kind of multiflora Gou catechu layering treatment and multiplication method

technical field

The invention relates to the technical field of plant planting, in particular to a multiflora catechu multiflora layering treatment and multiplication method.

Background technique

Berchemia floribunda (scientific name: Berchemia floribunda (Wall.) Brongn.) is a plant of the genus Berchemia floribunda in the family Rhamnaceae, a vine-like or erect shrub; young branches are yellow-green, smooth and hairless. Leaves papery, upper leaves smaller, ovate or ovate-elliptic to ovate-lanceolate. Flowers numerous, usually several clustered in terminal broad thyrses, or lower part and axillary cymes. Drupe cylindrical-elliptic, 7-10 mm long, 4-5 mm in diameter, fruiting stem 2-3 mm long, glabrous. The flowering period is July-October, and the fruit period is April-July next year. The root of Gouta multiflora is used as medicine, which has the effects of dispelling wind and dampness, dispelling blood stasis, reducing swelling, and relieving pain; farmers often use the branches as ox nose rings; the young leaves can replace tea. Goucatecha multiflora is an excellent fruit-watching tree species, with strong germination ability and pruning resistance. Its branches and leaves are bright, and the soft branches are light and light, which is quite distinctive. In the golden autumn season, there are many fruits, red and colorful, and it is an excellent fruit viewing plant. It can be used for park decoration, flower bed landscaping, etc., and can be used as shrub layer configuration in urban forest landscape construction. In addition, it has a long flowering period, a large amount of flowers, and a rich nectar flow, so it can be used as an excellent auxiliary nectar source plant.

High-branch layering refers to ring-peeling, cutting, and hanging semi-lignified branches, wrapping the wound with moist nutrient soil and waiting for it to take root. After rooting, cut off the mother plant and transplant it to become a new plant. High-branch layering has the advantages of rapid rooting, high survival rate, good traits of the mother plant, long physiological age, and early production. It is a breeding method with a wide range of adaptation. It is widely used in longan, litchi, citrus, rose, and camellia in production. and other plant reproduction. Since G. multiflora is mostly in the wild state, it has high requirements on the microenvironment and microclimate, and has habitat specificity, seed abortion and seed dormancy. The reproduction rate is low in the natural environment, and it is difficult to regenerate. The damage was severe, resulting in a significant reduction in the distribution of wild plants. So far, there has been no report and research on the conventional artificial propagation of G. multiflora. Therefore, the research on efficient breeding technology is of great significance to the restoration and reconstruction of its habitat, germplasm breeding and garden development and promotion.

Detailed ways

The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention.

Please refer to Fig. 1, the present invention provides a kind of technical scheme: a kind of multiflora catechu tea layering treatment multiplication method, its method comprises the following steps:

Step 1, matrix ratio:

Perlite, peat, and vermiculite are selected as the substrate for the layering treatment of Glycine multiflora, and the perlite, peat, and vermiculite (1:1:1) are mixed with water to prepare the substrate for the layering treatment of Glycine multiflora.

Step 2, the type of growth regulator is determined:

NAA naphthalene acetic acid is selected as the growth regulator for multiflora layering treatment and multiplication. Naphthalene acetic acid is an organic compound with a molecular formula of C12H10O2, referred to as NAA. It is insoluble in water, but slightly soluble in hot water, and in a humid environment It is easy to decompose and has the function of plant growth regulator, but it is a poisonous product. Relevant protective measures should be taken when using it. By choosing NAA naphthalene acetic acid as the growth regulator for the multiflora layering treatment and multiplication, it can maximize the promotion The multiplication efficiency of multiflora Goucatecha layering treatment;

Step 3. The concentration of the growth regulator, the concentration of NAA naphthalene acetic acid is 400mg/L. After the preparation is completed, apply it to the wound and around the wound, and repeatedly apply it 3 times.

Step 4, branch selection:

The adult plants of G. multiflora with good growth condition, smooth bark and no damage, no diseases, insects and parasites were selected as test materials. Select 1-2 year old healthy, vigorous growing, no mechanical damage, 0.5-0.8mm thick stem branches as layered branches, which can greatly improve the efficiency of multiflora Goucatecha layering treatment and multiplication,

Step 5, girdling treatment: The girdling width is 8mm. According to the experiment, we have concluded that in the operation of girdling treatment for the multi-flowered catechu layer, the girdling width is kept at 8mm, which can greatly improve the multi-flowered hook. The survival rate of tea layering propagation,

Step 6, layering treatment operation: perform wounding treatment on the smooth place 50-100 cm away from the base on the layering branch. Prune off excessive branches on the plywood branches, peel off the cortex of the branches in a ring shape with a cutting knife, the depth of the girdling is based on the principle of cutting off the phloem, but not hurting the xylem, and scrape the cambium lightly. According to different experiments Girdling of different widths is carried out for treatment. After girdling, 70% alcohol is used to disinfect, and then the prepared growth regulator is applied to the wound and around the wound, and the brushing is repeated 3 times. Put different proportions of matrix soil into the oven for 120°C high-temperature sterilization for 3 hours, pour it thoroughly with distilled water after cooling, fill it into the high-pressure box, wrap the incision site, make the wound closely contact with the matrix soil, tie the upper and lower openings of the high-pressure box and fix it , to avoid matrix outflow. After the layering is completed, water it with a syringe every 3-4 days according to the weather conditions. The resulting layering has a higher rooting rate (90-90%) and is suitable for seedling propagation.

To sum up, the multiflora catechu multiflora layering treatment multiplication method, when in use, first screens the multiflora catechu catechu branches that need to be layered, and after screening, it is placed on the smooth part of the layered branch 50-100cm away from the base. Perform girdling wound treatment, disinfect with 70% alcohol after girdling, and then apply the prepared growth regulator to the wound and around the wound, and repeatedly brush 3 times. Put different proportions of matrix soil into the oven for 120°C high-temperature sterilization for 3 hours, pour it thoroughly with distilled water after cooling, fill it into the high-pressure box, wrap the incision site, make the wound closely contact with the matrix soil, tie the upper and lower openings of the high-pressure box and fix it , to avoid matrix outflow. After the layering is completed, use a syringe to water once every 3-4 days according to the weather conditions.
