Embodiment 1

[0015] In late June, on cloudy or light rainy mornings, on the selected high-quality cold-resistant plants, collect the branches of the current year in the middle of the crown on the sunny side, with heels at the base (a very short part of the biennial branches), and the length is 10-12cm. Prune the harvested twigs of the year, because the leaves of red fennel with lanceolate leaves are longer, and half of the upper leaves are cut off. The cuttings are placed on a sterilized cutting bed, and the cutting substrate is a mixed substrate of peat soil: perlite: sand: vermiculite = 1:1:1:1 (volume ratio). Put the lower part of the trimmed branches into a plastic bucket filled with a prepared IAA50ppm solution, soak to a depth of 3-4cm, and soak for 24 hours. Cut the soaked cuttings on the cutting bed. The cutting depth is 4-5cm, and the cutting density is 6cm×8cm. Carbendazim 1000 times solution for disinfection;. Install sunshade nets and automatic spraying devices above the cutt...

Put the lower part of the trimmed branches into a plastic bucket filled with the prepared IAA50ppm+IBA50ppm solution, soak at a depth of 3-4cm, and soak for 24 hours. Cut the soaked cuttings on the cutting bed. The cutting depth is 4-5cm, and the cutting density is 6cm×8cm.

Abstract

The invention relates to a cold-resistant excellent lance-leaved red anise strain cutting propagation technology for evergreen broad-leave ornamental tree species illicium lanceolatum, which comprises the steps of sterilizing a cutting pond; mixing mediums which consist of peat soil, pearlite, sand and vermiculite according to volume ratio of 1:1:1:1, sterilizing a seedling bed by using potassium permanganate solution with concentration being 0.5 percent, sterilizing the mediums by using 50% Mildothane 800-time solution and keeping the thickness of cutting mediums to be 30cm; selecting annual shoots at the middle part of the sunny side of a crown, keeping the length of the shoots to be 10cm to 12cm and cutting off one half of leaves at the top end of the shoots for cutting; using IAA50ppm+IBA50ppm to treat scions and soaking 3cm-long to 4cm-long lower part of the shoots for cutting for 24 hours; keeping cutting depth to be 4cm to 5cm, keeping cutting density with row spacing being 6cm * 8cm and using a sprinkling can to spray water to enable the shoots for cutting to be in full contact with the mediums; and arranging a sunshade net and an automatic spray device above the cutting pond to reduce illumination intensity and increase air humidity, and in the first month after cutting, keeping daytime relative humidity above 65 percent to 80 percent. The survival rate of cut shoots can reach 80 percent. By using the annual shoots and after hormone treatment, the propagation of cold-resistant excellent lance-leaved red anise strains can be conducted rapidly, the method is simple, the operation is simple, the survival rate is high and the like. The technology not only can provide technical supports and excellent strain seedlings for the popularization and the application of lance-leaved red anises which are evergreen broadleaved ornamental trees, but also can provide references for the cutting propagation of the cold-resistant excellent strains of other trees.

Description

technical field [0001] The invention belongs to the technical field of plant vegetative propagation, and in particular relates to a cutting propagation method for cold-resistant superior plants of the evergreen broad-leaved shrub lanceolate red fennel. Background technique [0002] Coniferous red fennel is an evergreen small tree or shrub of the family Octagonalaceae. The leaves are green all year round. The leaves are narrow and long. They often gather on the top of the branches to form a dense crown. The young branches are usually yellow-green, and the follicles are yellowish-brown or reddish-brown when they mature. , the endocarp is often red, with a strong star anise aroma; the flower color is crimson or bright red, the perianth is fleshy, crystal clear, very beautiful, and it is very bright and eye-catching against the backdrop of emerald green leaves. This species has strong disease resistance, and no damage by diseases and insect pests was found during the introductio...
