Abstract

The invention discloses a germination method of dendrobium officinale Kimura et Migo, and belongs to the field of Chinese medicine planting. The method comprises the steps that 1, seeds are collected,dried at low temperature and stored at a cool and dry place of a refrigerating chamber at 0-4 DEG C; 2, the seeds are cleaned and disinfected with potassium permanganate and then flushed with clear water; 3, the seeds are soaked with warm water at 30 DEG C for 5 hours, fished out, then placed on filter paper or gauze under natural illumination and placed at a dark place at 22-28 DEG C; 4, after the seeds begin to germinate, the seeds are transferred to a germination culture medium, wherein the germination culture medium is disinfected sawdust, and the sawdust is mixed with crushed mosses andmud; 5, after seedlings in the fourth step germinate, the whole culture medium of the fourth step is transferred into a seedling raising culture medium, water is sprayed to keep moist, illumination iscarried out for 2-4 hours under natural light, and shading storage is carried out at other times; 6, after the seedlings are 3 cm high, the seedlings can be transferred to a greenhouse for normal cultivation. The double culture mediums adapt to parasitic characteristics, the nutritional needs of the dendrobium officinale Kimura et Migo at different stages are met, and particularly by adding the crushed mosses, a moisturizing layer and a protective film can be formed in the cultivation process.

Description
