Problems solved by technology

The current production raw materials mainly rely on imported wild Dracaena saponifera, not only the supply of raw materials is difficult to guarantee, but also the production cost has increased significantly, and the production of enterprises is facing the threat of raw material depletion at any time
How to realize the artificial cultivation of sword leaf dracaena, there is no successful report yet in the prior art

Embodiment 1

[0016] In March of that year, select the branches of Dracaena glabrata that have grown for more than 2 years and have a diameter of 1.5 to 3.0 cm, and collect them for later use; in a cool place, cut the upper end of the branch flat, and cut the base of the lower end into a slope with an inclination of 45 degrees to make 35 For centimeter-long cuttings, the surface of the cuttings at both ends should be smooth and lint-free; heat and melt the paraffin in a container, then immerse the upper end of the cuttings in paraffin wax for 0.5-1.0 cm and take it out immediately, so that the upper cutting surface is sealed by paraffin; The cut surface at the lower end is soaked in 100PPM rooting powder aqueous solution for 1.5 hours; the soaked cuttings are cut in a clean and moist sand bed. The sand bed is 20 centimeters high and 1.3 meters wide. There is a 40-centimeter walkway between the sand bed and the sand bed. The sand bed is built in a shade shed with a height of 2.5 meters. The s...

Embodiment 2

[0018] Repeat embodiment 1, following difference is arranged: the lower end cut surface part of cuttings is placed in the rooting powder aqueous solution of 500PPM and soaks for 10 seconds, takes out and places cuttage after 1 hour;

Embodiment 3

[0020] Repeat embodiment 1, following difference is arranged: the lower end cut surface part of cutting is dipped in the rooting powder powder, and the medicinal powder is coated on the lower end cut surface of the cutting, and then cuttage is carried out;

Abstract

The invention discloses a method of propagation by cuttings for dracaena cochinchinensis SC chen, which consists of selecting branches of dracaena cochinchinensis SC chen trees with an age of over two years, cutting the upper end of the branches, cutting the lower end to 40-50 degree of inclined surface, sealing the upper extreme tangent plane of the grafting ear with paraffin wax, immersing the lower end tangent plane in aqueous solution of root-producing powder, carrying out cuttage by the conventional process and transferring into large field planting.

Description

technical field [0001] The invention belongs to the technical field of plant cultivation, and in particular relates to a cutting propagation method using branches of Dracaena glabrata. Background technique [0002] Dracaena cochinchinensis (Dracaena cochinchinensis) is an evergreen tree of Agaveaceae, with a height of up to 15 meters and a diameter of up to 140 centimeters. It has many branches, and the crown is umbrella-shaped, and the bark is off-white and smooth. After the trunk is injured, the xylem on the injured surface will turn purple after a long time due to the accumulation of resin, and the thickness of the purple xylem can reach 1 cm. Its leaves gather at the top of the branches and overlap each other. The leaves are thin and leathery and sword-shaped. The flowers are terminal scattered panicles, densely covered with setae, and small flowers are solitary. The full flowering period is from late February to early March, and the fruit ripening period is from July t...
