Embodiment Construction

[0009] Collection of cuttings: The collection of cuttings can be combined with pruning in late spring and early summer. Usually, the middle and upper branches of two-year-old strong branches are collected. Because the branches and buds are full and rich in storage nutrients, they are good for rooting.

[0010] Cutting treatment: Before cutting, cut the collected branches according to the requirements of cuttings, cut into double-bud cuttings, and cut the cuttings into a horse-ear-shaped single bevel.

[0011] In order to improve the rooting rate and the survival rate of cuttings, the cuttings should be treated:

[0012] (1) Water immersion treatment. Cuttings should be cut in the early morning of the cutting day and placed in a bucket with clean water to make them fully absorb water to supplement the water lost in the cuttings and restore the turgor and vitality of the cells.

[0013] (2) Detoxification and antiseptic treatment. The cuttings are not clean, the meristem cells on the ...

Abstract

The invention belongs to the technical field of plant cultivation and particularly relates to a cuttage method of vitex. Biennial robust branches of the vitex are taken to be used as cutting slips, the length of the cutting slips is 12-18 centimeters, and the number of buds on the cutting slips is 2. The cutting slips are disinfected through eluant prepared through 3% alcohol for 2 hours before cuttage. A cuttage medium is perlite. A cuttage pond is disinfected before the cuttage. The perlite is required to be disinfected. During cuttage, a cuttage medium is sprayed with water, and the cutting slips are soaked for 2 hours in a solution of NAA200ppm+IAA200ppm. The depth of the cutting slips entering soil is about one third of the length of the slips and can not exceed half of the length of the slips, a line interval of the cuttage strains is 5x5 centimeters, the medium is required to keep moist after the cuttage, mist spraying at regular time is required, interval mist spraying devices are required, and mist is sprayed for 30 seconds at an interval of 15 minutes so as to keep certain moisture. After cuttage, a cuttage bed and the medium are disinfected at regular time. The temperature ranges from 20 to 25 DEG C during cuttage. The cuttage is conducted from May to June and can not be conducted during a flowering phase.

Description

technical field [0001] The invention belongs to the technical field of plant cultivation, and in particular relates to a cutting method of Vitex vitae. Background technique [0002] Vitex ( Vitex negundo var. cannabifolia ) is a deciduous shrub or small tree of the Verbenaceae Vitex genus. Branchlets square, densely gray-white tomentose. Leaves opposite, palmate 5 compound leaves, leaflets with many serrations on the edge, green above, light green below, glabrous or slightly hairy. Inflorescence panicle terminal; calyx bell-shaped, with 5-lobes at the top; corolla lavender, with 5-lobes at the top. The fruit is spherical, called "Huangjingzi", yellowish brown to tan, is an important medicinal material, has anti-cancer effects, and can also extract aromatic oil. The flowering and fruiting period of vitex is from July to November, which coincides with the period when there are few flowers in summer and autumn in the garden, so it is very ornamental. [0003] At present...
