Embodiment 1

[0034] 1. Field selection and arrangement

[0035] Choose the 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°C, and the water source is convenient. Lay the ground and make it level to no rubbish. Start a low ridge with a width of 150-200cm and a depth of 20-25cm. Spread plastic sheeting on the ridge, and sprinkle the insecticide dichlorfon between the plastic sheeting and the soil. .

[0036] 2. Prepare the seedling substrate and put it on the plate

[0037] Mix fermented bark powder with humus, nutrient soil, chicken manure, and peat soil at a volume ratio of 15:20:8:1:5, and mix the resulting mixture with carbendazim at a volume ratio of 1000:5. , prepare the seedling substrate, fill the prepared seedling substrate with 70 hole seedling trays, the diameter of the top of the seedling tray is 5cm, the diameter of the bottom is 1.5cm, and the depth of the hole...

Embodiment 2

[0048] In this embodiment, the fermented bark powder, humus, nutrient soil, chicken manure, and peat soil are mixed evenly in a volume ratio of 5:25:5:1:8, and the resulting mixture and carbendazim are in a volume ratio of 1000:5 Thoroughly mix and prepare the seedling-raising substrate, and other steps are the same as in Example 1. The picture of the plant 105 days after sowing the seeds of Baiji is shown in image 3 .

Embodiment 3

[0050] In this embodiment, the fermented bark powder, humus, nutrient soil, chicken manure, and peat soil are mixed evenly in a volume ratio of 30:5:10:1:3, and the resulting mixture and carbendazim are in a volume ratio of 1000:5 Thoroughly mix and prepare the seedling-raising substrate, and other steps are the same as in Example 1. The picture of the plant 105 days after sowing the seeds of Baiji is shown in 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...
