[0040] 1. Selection of sowing area

[0041] In the Qinba Mountains, the area with rich rock resources at an altitude of 700-1600 meters is selected as the sowing site. The rock type is sandstone, the annual average temperature is 12-18°C, the extreme maximum temperature is below 34°C, the extreme minimum temperature is above -10°C, and the frost-free period is 200 days Above, the relative air humidity is above 60%, and the forest coverage rate is above 50%.

[0042] 2. Selection of seeding carrier

[0043] 2.1 In the mountainous and rocky areas, sandstones of different sizes are selected locally, and the size of each stone is between 6×7cm-20×25cm, so as to facilitate the handling and management of stones and the fixing of seed bags. If you choose too large stones, not only is it inconvenient to carry, but also the management in the later stage is very laborious, and it is not conducive to the fixing of the seed bag;

[0044] 2.2 After choosing the stone, it is necessary to ...

Abstract

The invention provides a bacterial strain and method for promoting germination of medicinal dendrobium seeds on stones to form seedlings. The bacterial strain is Sebacinales sp.LQ in Latin name; the preservation unit is China center for type culture Collection; the preservation number is CCTCC NO: M 2019744; the preservation time is September 23<rd>, 2019; and the preservation address is Wuhan university, Bayi road, Wuchang District, Wuhan City, Hubei Province, China. The medicinal dendrobium flexicaule symbiotic seedlings suitable for rock cultivation are specifically germinated on the stones. According to the bacterial strain and method for promoting germination of the medicinal dendrobium seeds on the stones to form the seedlings, the cultivated land is not occupied, scattered stone resources are fully utilized, later management is facilitated, and a new planting mode of the medicinal dendrobium on the stones is formed, wherein the new planting mode integrates low investment, high quality, ornamental and economic benefits.

Description

technical field [0001] The invention belongs to the technical field of field planting of medicinal dendrobium, and in particular relates to a bacterial strain and a method for promoting the germination of medicinal dendrobium seeds on stones to form seedlings. Background technique [0002] Dendrobium ( Dendrobium ) is the second largest genus of Orchidaceae. There are more than 1,500 species in the world, and about 80 species in my country, of which nearly 40 species have medicinal value. Dendrobium curved stem ( Dendrobium flexicaule ) is a relatively rare medicinal species in the genus Dendrobium, which can be traced back to the Tang Dynasty "Taishang Elbow Hou Yujing Prescription" (825 AD), with a history of 1191 years so far. Dendrobium candidum is distributed in the northernmost margin of the Dendrobium distribution area, reaching 34°24' north latitude, and concentrated in the Qinba mountainous areas such as eastern Chongqing, northeastern Sichuan, western Hubei, nor...
