Embodiment 1

[0026] 1. Picking and preservation of white and pods

[0027] The fully developed bletilla pods with an embryo age of more than 18 weeks were selected for picking, and the picked bletilla pods were packed into kraft paper bags, dried in a ventilated and cool place, and stored in a refrigerator at 4°C.

[0028] 2. Preparation of matrix

[0029] Select humus, river sand, and fermented bark, mix the fermented bark, humus, and river sand evenly at a mass ratio of 2:4:1, spray carbendazim and soil insecticide, and prepare a substrate.

[0030] The above-mentioned insecticides are net insecticides in bags, provided by Wuwei County Flower Fertilizer Factory in Anhui Province.

[0031] 3. Seed sowing and seedling raising

[0032] Plane the pods after the low-temperature treatment in step 1 along the longitudinal ribs, take out the seeds in the pods, mix the seeds and plant ash in a volume ratio of 1:500, spread the substrate prepared in step 2 on the seedling dish, The thickness of...

Embodiment 2

[0039] 1. Picking and preservation of white and pods

[0040] The fully developed bletilla pods with an embryo age of more than 18 weeks were selected for picking, and the picked bletilla pods were packed into kraft paper bags, dried in a ventilated and cool place, and stored in a refrigerator at 4°C.

[0041] 2. Preparation of matrix

[0042] Select humus, river sand, and fermented bark, mix the fermented bark, humus, and river sand evenly in a mass ratio of 1:3:1, spray carbendazim and soil insecticide, and prepare a substrate.

[0043] 3. Seed sowing and seedling raising

[0044] Plane the pods after the low-temperature treatment in step 1 along the longitudinal ribs, take out the seeds in the pods, mix the seeds and plant ash at a volume ratio of 1:1000, spread the substrate prepared in step 2 on the seedling dish, The thickness of the substrate is 1 / 2 of the depth of the seedling dish. Spread 2 layers of gauze on the substrate, water the substrate to soak it, and use a ...

Embodiment 3

[0051] In the preparation matrix step 2 of Examples 1-2, humus, river sand and fermented bark were selected, and the fermented bark, humus, and river sand were mixed evenly according to the mass ratio of 5:8:1, and sprayed more Bactazim and insecticides, formulated as a matrix. Other steps are the same as the corresponding embodiment.

Abstract

Provided is a bletilla striata rapid propagation seedling cultivation method. Fermented bark and a mixture of humus and river sand serve as a base material, the base material is laid on a seedling cultivation vessel, 1-2 layers of gauze is laid on the base material, water is poured to soak the base material, bletilla striata seeds are sown on the gauze, a transparent plastic film is utilized to wrap the seedling cultivation vessel, and the seedling cultivation vessel is placed in an artificial intelligent cultivation box to grow seedlings and strengthen the seedlings. The bletilla striata rapid propagation seedling cultivation method breaks through a traditional corm planting and cultivation mode of bletilla striata, the quality degeneration problem existing in vegetative propagation is resolved, and a new path is created for sexual propagation seedling cultivation of the bletilla striata genus of orchidaceae. The bletilla striata rapid propagation seedling cultivation method is simple in operation, low in cost and short in seedling cultivation period; the germination rate reaches up to 90%, the planting percent is 70%-80%, and good practical popularization significance is provided for large-scale propagation seedling cultivation 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 method for rapidly propagating seedlings of the orchid plant Radix chinensis. Background technique [0002] Bletilla striata (Thunb.ex A.Murray) Rchb) is a plant of the genus Bletilla striata, mainly produced in Guizhou, Sichuan, Hunan, Hubei, Henan, Zhejiang, Shaanxi and other places. Baiji is a traditional Chinese medicine in my country. The medicinal part is the underground pseudobulb, which has the effects of astringent and hemostasis, nourishing qi and promoting body fluid, promoting muscle growth and relieving pain. Recent research results show that the chemical composition of a large amount of water-soluble polysaccharides in Pseudomonas baicalensis is glucomannan, and its physical and chemical properties are basically similar to gum arabic and tragacanth gum, which can replace them as suspending agents and emulsifiers for food...
