Example Embodiment

[0033] Example 1

[0034] 1. Selection and arrangement of fields

[0035] Choose a field in Yongle Town, Zhen'an County, Shangluo City, Shaanxi Province, where the annual precipitation reaches 800-1200mm, the annual average temperature is above 14℃, and the water source is convenient to build a plastic greenhouse with a length of 100m and a width of 20m. The bottom is solid, leveled until there is no rubbish, and low ridges are formed. The ridge width is 150-200cm and the ridge depth is 20-25cm. Spread the plastic sheet on the ridge, and sprinkle the insecticide dichonwei between the plastic sheet and the soil. .

[0036] 2. Prepare seedling substrate and load it on a plate

[0037] Mix the fermented bark powder with humus, nutrient soil, chicken manure, and turf soil in a volume ratio of 15:20:8:1:5, and mix the resulting mixture with carbendazim in a volume ratio of 1000:5. , Formulated into a seedling substrate, fill the prepared seedling substrate with 70-hole seedling plugs. Th...

Example Embodiment

[0047] Example 2

[0048] In this example, the fermented bark powder and humus, nutrient soil, chicken manure, and turf soil were uniformly mixed in a volume ratio of 5:25:5:1:8, and the resulting mixture and carbendazim were in a volume ratio of 1000:5. Mix thoroughly and prepare a seedling substrate. The other steps are the same as in Example 1. See the plant picture 105 days after sowing of Baiji seeds image 3 .

[0049] Example 3

[0050] In this example, the fermented bark powder and humus, nutrient soil, chicken manure, and turf soil were mixed uniformly in a volume ratio of 30:5:10:1:3, and the resulting mixture and carbendazim were in a volume ratio of 1000:5. Mix thoroughly and prepare a seedling substrate. The other steps are the same as in Example 1. See the plant picture 105 days after sowing of Baiji seeds Figure 4 .

Abstract

The invention discloses a propagation method of bletilla striata. The propagation method comprises the following steps: selecting and tidying a field; preparing seedling raising substrate; filling the seedling raising substrate in trays, preserving pods, treating seeds, seeding, raising seedling, managing the field and toughening seedlings. The propagation method is simple, feasible, low in cost, fast in seedling emergence, suitable for the planting of bletilla striata in the Qinba mountain area and the areas south of the Qinba mountain area and easy to popularize, and can fully meet the requirements of large-area large-scale seedling raising. The propagation method overcomes the difficulty that germinating is difficult for seeds under the natural conditions because the seeds are small and do not have endosperm, and opens up a new approach for the fast sexual propagation of the bletilla striata.

Description

technical field [0001] The invention belongs to the technical field of artificial planting of medicinal plants, and in particular relates to a field planting method of the endangered medicinal plant Baiji. Background technique [0002] Bletilla striata (Bletilla striata) is a perennial herbaceous plant belonging to the Orchidaceae Bletilla striata. It is a national second-class endangered plant. It is mainly distributed in Guizhou, Hubei, and southern Shaanxi in the south of the Qinling Mountains in my country. Generally, it grows under the evergreen broad-leaved forest at an altitude of 100-3200 meters, in the grass on the roadside or in the crevices of rocks. Its rhizome is white, and several are connected, hence the name Baiji or Baigen. [0003] There are about 6 species of plants in the genus Baiji, which are distributed in East Asia and west to Myanmar. my country is the main production area. There are four species in total, namely Huabaiji, Xiaobaiji, Baiji and Huan...
