Problems solved by technology

Tang Yan summarized the cutting propagation techniques of A. nudiflora from the aspects of site selection, site preparation, selection of branches, cutting of spikes, cuttings, seedbed management, and nursery standards. Although it was treated with indole butyric acid, it did not mention and optimal concentration and soaking time, no cutting rooting and propagation evaluation, weak operability (Pipetia nudiflora cutting propagation technology, Agricultural Technology Service, 2012, 29(9): 1026)
Zhang Lang et al. studied the cutting seedling raising technology of A. nudiflora from the aspects of cutting age, thickness, and rooting drug treatment. They mainly carried out research on three aspects: cutting age, cutting thickness, and rooting dosage treatment. The problems are: (1) The rooting rate of current-yea

Embodiment 1

[0046] (1) Preparation of cuttings: Collect the seeds of the excellent strain of wild nudibranch (tree height ≥ 4m, breast diameter ≥ 10cm) in Wuzhishan, Hainan, sow and raise seedlings in Guangzhou; then choose a ground diameter of not less than 0.5cm and a seedling height of not less than 50cm The excellent seedlings of the two years are used to construct the ear picking garden; the semi-lignified, lower end diameter branches of 0.30 to 0.39 cm are selected as the cutting material from the ear picking garden;

[0047] (2) Preparation of mixed substrate: Mix peat soil: vermiculite: river sand evenly in a volume ratio of 2:1:1, and place them in a 50-hole lightweight seedling tray with a length of 540 mm, a width of 280 mm, and a depth of 80 mm. Two days before the cuttings, use 0.5% potassium permanganate solution for disinfection by sprinkling. The mixed substrate shall prevail. The light plugs for cuttings used in this operation have the advantages of saving substrates, savi...

Embodiment 3

[0069] (1) Preparation of cuttings: Collect the seeds of the excellent strain of wild nudibranch (tree height ≥ 4m, breast diameter ≥ 10cm) in Wuzhishan, Hainan, sow and raise seedlings in Guangzhou; then choose a ground diameter of not less than 0.5cm and a seedling height of not less than 50cm The fine seedlings of these plants are used to construct the ear-picking nursery; select 2-year-old seedlings from the ear-picking garden, which are semi-lignified in the current year, and branches with a lower end diameter of 0.30 to 0.39 cm are used as cuttings;

[0070] (2) Preparation of mixed substrate: Mix peat soil: vermiculite: river sand evenly in a volume ratio of 1:1:1, and place them in a light seedling tray with 50 holes of length 540mm, width 280mm, and depth 80mm. 2 days before the cuttings, use 0.5% potassium permanganate solution for irrigation and disinfection, and the mixed matrix shall prevail.

Abstract

The invention belongs to the technical field of vegetative propagation of plants and particularly relates to a rapid propagation method of callicarpa nudiflora. The method comprises the following steps of 1 preparing ear seedlings; 2 preparing a mixed matrix; 3 preparing and cutting cuttings; 4 performing later period management and maintenance. By means of the rapid propagation method, the time required for rooting can be effectively shortened, the rooting percentage is obviously improved, the root number and the maximum root length are obviously increased, and the root slanting rate is reduced. The seedling emergency percentage of produced nursery stocks and survival rate of transplanted nursery stocks are high. Good characters of stock plants can be kept stable and reliable by means of the rapid propagation method. The rapid propagation method is low in cost and easy to popularize technologically and has wide application prospect.

Description

technical field [0001] The invention belongs to the technical field of plant vegetative propagation, and in particular relates to a method for rapid propagation of the nude flower purple pearl. Background technique [0002] Callicarpa nudiflora Hook.et Am. is a perennial shrub to small tree of the genus Callicarpa in the family Verbenaceae. Mainly distributed in tropical and subtropical regions, such as India, Vietnam, Malaysia, Singapore and northern Australia. Domestically, it is mainly distributed in Hainan, Guangdong and Guangxi. The whole plant of Nadihua Zizhu can be used as medicine. It has a long history of medicinal use. It has the effects of antibacterial, hemostasis, detoxification and anti-inflammation, dispelling wind and dampness, and anti-tumor. Naked flower purple pearl is a large authentic medicinal material in Hainan Province, and it is also a commonly used medicinal material by the Li nationality in Hainan. Not only has it been included in the local med...
