Tissue culturing method of radix zanthoxyli

Abstract

The invention relates to a tissue culturing method of radix zanthoxyli and belongs to the technical field of crop planting. The tissue culturing method comprises six steps of material pretreatment, inoculation, culture, transplantation, cultivation management and seedling delivery out of a garden. The tissue culturing method comprises the specific steps of: on a fine day, selecting a good plant with strong growth and no disease and pest damage, washing with tap water, soaking the plant for 6-8 minutes in potassium permanganate solution, washing for 2-3 times with aseptic water, cutting the plant into small sections which are 0.5-0.8cm in length and have sprouts under the aseptic condition, inoculating the small sections on a culture medium under the aseptic condition, and culturing for 4-5 days under the condition with the temperature being 30-35 DEG C; after the culture is complete, carrying out seedling exercise for 3-5 days on seedlings under natural environment, transplanting the seedlings onto a matrix after adapting to the natural condition, and carrying out cultivation on the seedlings under the condition with the temperature being 25-35 DEG C and the humidity being 50-70%; after transplanting, watering for maintaining the soil to be wet, applying fertilizers once every week, and after 4-5 months, when the height of the seedlings is more than 20cm, the seedlings can be delivered out of the garden for planting. The success rate of the radix zanthoxyli planted by adopting the tissue culturing method is highest and is up to more than 95%; the culturing method is simple, is short in culture time and is beneficial to large-scale production.

Description

technical field [0001] The invention relates to a method for tissue culture of plants, in particular to a method for tissue culture of double-faced needles with multiple functions, and belongs to the technical field of crop cultivation.
