Problems solved by technology

But now people use the seeds of Angelica dahurica to cultivate them for sexual reproduction, and their genetic characteristics will change relative to the mother. The active ingredients will be reduced, the efficacy will be reduced, and the seeds are difficult to collect, the number is limited, and the survival rate is low. , grows slowly, and cannot meet the needs of large-scale development of Angelica dahurica planting

Embodiment 1

[0017] Embodiment 1: a kind of Angelica dahurica cutting seedling cultivation, its concrete steps are as follows:

[0018] 1. Pick biennial stems and branches of Angelica dahurica that are robust and free from diseases and insect pests, and cut them into 20 cm long cuttings with 2 nodes;

[0019] 2. Soak with phytohormone naacetic acid (NAA) at a concentration of 110mg / L for 2 hours;

[0020] 3. Use a small shovel to open a ditch 18 cm deep on the prepared sand bed, place the treated cuttings obliquely into the ditch at a distance of 5 cm, the cuttings are 70 degrees to the sand surface, cover the sand, and insert the cuttings The sand depth is 2 / 3 of its length, and the row spacing is 25 cm;

[0021] 4. Sprinkle water once a day in the morning and evening after transplanting to keep the substrate moisture at 65% to 68%;

[0022] 5. Use sunshade nets to set up a shed for shade, avoid direct sunlight, and control the temperature in the shed between 28°C and 30°C;

[0023] 6....

Embodiment 2

[0025] Embodiment 2: a kind of Angelica dahurica cuttage seedling cultivation, its concrete steps are as follows:

[0026] 1. Pick biennial stems of Angelica dahurica dahurica that are robust and free from diseases and insect pests, cut them into 25 cm long cuttings with 3 nodes;

[0027] 2. Soak with 120 mg / L plant hormone indole butyric acid (IBA) for 3 hours;

[0028] 3. Use a small shovel to open a ditch 18 cm deep on the prepared sand bed, and put the treated cuttings obliquely into the ditch at a distance of 6 cm. The cuttings and the sand surface are at 80 degrees. The sand depth is 2 / 3 of its length, and the row spacing is 30 cm;

[0029] 4. Sprinkle water once a day in the morning and evening after planting to keep the substrate moisture at 68% to 70%;

[0030] 5. Use sunshade nets to set up a shed for shade, avoid direct sunlight, and control the temperature in the shed between 30°C and 32°C;

Abstract

The invention discloses a seedling raising method for Angelica dahurica by cutting, belonging to the technical field of cultivation of Chinese medicinal materials. The seedling raising method comprises the following six concrete steps: branch collecting and pruning, soaking treatment with phytohormone, sand bed preparation and cutting, water spraying, shading, and removal of a sunshade net. The seedling raising method provided by the invention effectively solves the disadvantages of genetic characteristic changes, reduced effective components, decreased potency, difficulty in seed collection,limited quantities, low survival rate, slow growth and incapability of meeting the need of large-area development of Angelica dahurica planting for Angelica dahurica seedling raising in the prior art.The seedling raising method provided by the invention has the following beneficial effects: materials are conveniently available; procedures are simple; meanwhile, no genetic variation is generated;after transplantation is completed, rapid growth, stable yield and high yield can be realized; and stems and branches of the Angelica dahurica are easy to collect and large in number, so the need of large-area development of Angelica dahurica planting can be met.

Description

technical field [0001] The invention relates to the technical field of cultivation of Chinese herbal medicines, in particular to a method for growing seedlings of Angelica dahurica, in particular to a method for growing seedlings of Angelica dahurica through cuttings, and belongs to the technical field of cultivation of Chinese medicinal materials. Background technique [0002] Baizhi (Latin name: Angelica dahurica (Fisch. ex Hoffm.) Benth. et Hook. f.ex Franch. et Sav), tall perennial herb, 1-2.5 meters high, cylindrical root, stem base diameter 2-5 cm , basal leaves once pinnately divided, compound umbels terminal or lateral, fruit oblong to oval. [0003] The root is used as medicine, which has the functions of dispelling disease and dehumidification, draining pus and promoting granulation, promoting blood circulation and relieving pain. Indications for anemofrigid cold, headache, rhinitis, toothache. It can also be used as a spice for red and white vaginal discharge, p...
