AI Technical Summary

Problems solved by technology

So far, the existing technical achievements have mostly focused on the seed germination, tissue culture, and cultivation management of Dracaena plants. As a rapid propagation method, there are few reports on branch cuttings, which only involve research on hormone regulation. The field of seedling control is still blank

Embodiment 1

[0019] 1. Materials and methods:

[0020] On April 22, 2017, branches of dracaena dracaena with a diameter of less than 3cm were collected in Pu'er City, Yunnan Province, and the collected branches were cut into small sections of 20cm, a total of 50 sections, which were used as cuttings. Immerse the 2cm lower end of the cuttings morphology into the solution of ABT rooting powder content of 500mg / kg for 30 minutes, take it out, put it in a small bucket, inject 5cm deep water into the bottom, change the water every 5 days, and keep the ambient temperature at 20-25°C. Observe branch germination and rooting situation after 60 days.

[0021] 2. Results and analysis:

[0022] Table 1 Dracaena hydroponics results

[0023]

[0024] The experimental results show that the branches of Dracaena glabra can germinate and take root through hydroponics, which provides support for the further improvement of the technology in the later stage.

Embodiment 2

[0026] 1. Materials and methods:

[0027] On June 16, 2017, branches of Dracaena glabrata with a diameter of less than 3cm were collected in Pu'er City, Yunnan Province. The collected branches were cut into small sections of 20cm, and divided into three grades according to the average diameter: Ⅰ14- 18mm, Ⅱ18-22mm, Ⅲ22-26mm, 30 cuttings for each diameter grade. Immerse the 2cm lower end of the cuttings morphology into the solution of ABT rooting powder content of 500mg / kg for 30 minutes, take it out, put it in a small bucket, inject 5cm deep water into the bottom, change the water every 5 days, and keep the ambient temperature at 20-25°C. Observe branch germination and rooting situation after 60 days.

Embodiment 3

[0033] 1. Materials and methods:

[0034] On April 18, 2018, Dracaena dracaena branches with a diameter of about 2cm were collected in Pu'er City, Yunnan Province. The collected branches were cut into small sections of 20cm, and the lower 2cm of the cuttings morphologically were immersed in a solution of 500mg / kg of ABT rooting powder Remove after 30 minutes. They were placed in small buckets and in the cutting matrix of mountain base soil: river sand = 1:1, 50 cuttings in each group. Inject 5 cm deep water into the bottom of the small bucket, and change the water every 5 days; the cutting matrix cuttings are inserted to a depth of 5 cm and maintain humidity. Keep the ambient temperature at 20-25°C, and observe the germination and rooting of the branches after 60 days.

Abstract

The invention provides a rare and endangered medicinal plant dracaena cochinchinensis water planting rapid rooting and seedling method. The method comprises the following steps that dracaena cochinchinensis branches with the length being 20 m and the average diameter being 2 cm are cut out to serve as cuttings, 2 cm of the morphological lower ends of the cuttings are soaked in a solution with theABT rooting powder content being 500 mg / kg for 30 min and then taken out, the cuttings soaked in the rooting powder solution is placed in a clean bucket, clear water is injected in the bottom for 5 cmin depth, water changing is conducted once every 5-10 days, it is guaranteed that the water is clean, the environment temperature is kept at 20-25 DEG C, and after 60 days, the sprouted and rooted cuttings are transplanted and planted. Compared with seedlings cultivated through a tissue culture method, dracaena cochinchinensis seedlings cultivated through the method has the advantages of being low in cost, high in production value and the like, and the material basis, scientific basis and technical support are provided for species return to nature and population reconstruction realization.

Description

[0001] Field: [0002] The invention relates to the field of biotechnology, in particular to a method for rapid rooting and seedling growth of the rare and endangered medicinal plant Dracaena glabrata. Background technique: [0003] Dracaena cochinchinensis is a plant of the genus Dracaena in the family Liliaceae. There are more than 150 species of Dracaena plants in the world, mainly distributed in tropical and subtropical regions of Asia and Africa. There are 6 species native to my country. In 2001, it was listed as a second-class rare and endangered plant by the country. In "Chinese Plant Red Book - Rare and Endangered Plants". Dracaena fragrans is the raw material for extracting the precious traditional Chinese medicine—Dragon Blood. Dracaena has a good medical effect on various blood diseases. In ancient times, it was mainly used to treat bruises, tuna and other diseases, and it was also used in internal medicine. my country has a history of using dried blood for thousa...
