Embodiment Construction

[0019] The specific technical solutions of the present invention are described in conjunction with the examples.

[0020] (1) Seed collection and pretreatment: Collect the infructescences of Ginseng palmi in mid-to-late November, air-dry at room temperature to prevent browning and mildew, and then store alternately at -10°C and 4°C (alternating time 5 days, alternating times 4 ~ 7 times) preservation, cut the fruit before sowing to obtain seeds, mix the sterilized fine sand, spray gibberellin solution (concentration 5 ~ 10ppm), moderate humidity, suitable for sowing;

[0021] (2) Prepare the substrate: Prepare the seed germination substrate half a month before sowing the ginseng seeds. The substrate is made of coarse sand at the bottom of 4-5cm, the middle layer is 4-5cm thick and 10-mesh sawdust, and the surface layer is 1-2cm thick and is 20-mesh coconut bran. Composition, after the matrix combination is completed, it is sprayed with water and compacted. After the matrix is ...

Abstract

The invention belongs to the technical field of plant cultivation, and particularly relates to an industrialization breeding method of gymnadenia orchidis seedlings. The method comprises the steps that seeds are collected, air-dried and preserved, fruits are cut before sowing to obtain the seeds, the seeds are mixed with disinfected fine sand, a gibberellin solution is sprayed, gymnadenia orchidisseeds are sowed in a medium, soil coverage is conducted after the seeds are sowed, after the germinated seeds grow for one year, seedling transplanting is conducted at the end of the year, and tubersare screened for sand storage; after the gymnadenia orchidis tubers sprout in the early spring through sand storage, the tubers are planted on a compartment surface. By means of the method, the germination rate of the seeds is high and reaches 85-90%; the seedling emergence rate of sprouts is high.

Description

technical field [0001] The invention belongs to the technical field of plant cultivation, and in particular relates to a method for industrialized breeding of ginseng palm seedlings. Background technique [0002] Ginseng palm is the tonifying medicinal material of ethnic medicines such as Tibetan medicine and Mongolian medicine, and the dried tubers are used as medicine. Excavated in summer and autumn, removed fibrous roots and silt, dried in the sun, scalded in boiling water or boiled until there is no white heart inside, dried in the sun can be used as medicine. The base plant of the medicinal material Gymnadenia orchidis is mainly Gymnadenia orchidis, which is a plant of the genus Gymnadenia orchidis. The stems are upright, 17-35 cm high, and the stems are erect, thick, cylindrical, with 2-3 cylindrical sheaths at the base , with 3 to 5 leaves on it, and 1 to several bract-shaped leaflets on the upper part, the leaves are oval or oval-oblong, 4 to 16 cm long, (2.5-)3 to ...
