Problems solved by technology

At present, a large number of Bletilla striata seedlings are obtained by aseptic germination of Bletilla striata seeds, but the survival rate of the tissue-cultured seedlings after transplanting to the field is not high, which seriously restricts the industrialization of Bletilla striata

Embodiment 1

[0020] A method for domesticating bletilla striata seedlings, comprising:

[0021] (1) Seedling raising substrate: Mix peat, vermiculite and vermicompost in proportion and then add antibacterial agent. The weight ratio of peat, vermiculite and vermicompost in the seedling raising substrate is 6:3:1, and adjust the water content to about 30%. The seedling raising substrate is obtained; the substrate is put into a polystyrene foam seedling raising tray for use; the polystyrene foam seedling raising has 162 holes, and the outer dimension is 66.5cm×34cm×5.5cm.

[0022] (2) Disinfection of Bletilla striata seedlings: soak the roots of Bletilla striata seedlings in the antibacterial agent carbendazim solution for 10 minutes after hardening; drain the water; carbendazim is diluted 1000 times, and the concentration is 0.1%; The final bletilla striata seedlings are planted in the seedling tray, and then put into the seedling pond;

[0023] (3) Seedling management: After the Bletilla s...

Embodiment 2

[0026] A method for domesticating bletilla striata seedlings, comprising:

[0027] (1) Seedling-raising substrate: Mix peat, vermiculite and vermicompost in proportion and then add antibacterial agent. The weight ratio of peat, vermiculite and vermicompost in the seedling-raising substrate is 5:2:1, and adjust the water content to about 28%. The seedling raising substrate is obtained; the substrate is put into a polystyrene foam seedling raising tray for use; the polystyrene foam seedling raising has 162 holes, and the outer dimension is 66.5cm×34cm×5.5cm.

[0028] (2) Disinfection of Bletilla striata seedlings: soak the roots of Bletilla striata seedlings in the antibacterial agent carbendazim solution for 9 minutes after hardening; drain the water; carbendazim is diluted 1000 times, and the concentration is 0.1%; The final bletilla striata seedlings are planted in the seedling tray, and then put into the seedling pond;

[0029] (3) Seedling management: After the Bletilla st...

Abstract

The invention discloses a Bletilla striata seedling domestication method. The method comprises following steps: a seedling culture substrate is prepared; Bletilla striata seedlings are disinfected, Bletilla striata tissue culture seedlings are subjected to root soaking treatment in a bacteriostatic agent after exercising; then seedling culture management is performed: excessive water in a nursery pond is drained after the Bletilla striata seedlings in the nursery pond survive, so that the water content of the substrate is reduced gradually and naturally; irrigation is performed after the water content of the substrate is lower than 30%; irrigation is repeated after the water content of the substrate is lower than 30%; the seedlings are transplanted to a field: after alternation of drying and wetting and repeated irrigation for 45 days, single weight of Bletilla striata fruits is higher than 4 g, and the Bletilla striata seedlings are transplanted to the field for planting. Seedling domestication steps and method are optimized, scientific seedling culture management is adopted, so that a root rot phenomenon is avoided for the Bletilla striata seedlings after exercising, pathogens are inhibited by the bacteriostatic agent, reasonable fertilizer efficiency is guaranteed by multi-compound fertilizer, the Bletilla striata tissue culture seedlings can be domesticated rapidly, the transplanting survival rate of the Bletilla striata seedlings is increased remarkably, and the seedling culture cost is reduced.

Description

technical field [0001] The invention relates to the technical field of plant cultivation, in particular to a method for domesticating bletilla striata seedlings. Background technique [0002] Bletilla striata (Thunb.) Reichb.f., a rare and precious medicinal material, is a perennial herb of the genus Bletilla striata. It is a national key protected wild plant and has extremely high economic value. Bletilla striata is used as medicine with dried tubers, which has the effects of astringent and hemostasis, detumescence and muscle growth, and is widely used in the treatment of pulmonary tuberculosis, bronchiectasis, hemoptysis, gastric ulcer bleeding and other diseases. In addition to being used in medicine, bletilla striata tubers are rich in bletilla striata gum, bletilla striata gum can replace Xihuangjiao powder and gum arabic powder as emulsifier and suspending agent in food, beauty and chemical industries, and has a wide range of uses. [0003] In recent years, with the e...
