Embodiment 7

[0071] A kind of cultivation method of North American Sequoia, such as figure 1 shown, including the following steps:

[0072] S1, get the material, select the Sequoia twigs that were born in the current year as raw materials, and inoculate them into MS culture medium after disinfection and cleaning, and grow aseptic seedlings from the axillary buds after 20-22 days;

[0073] S2, proliferating culture, inoculating the sterile vaccine into the proliferating medium for proliferating culture. After 23-27 days of culture, a sterile vaccine is formed;

[0074] S3, strong seedlings, put the sterile seedlings formed after multiplication into the strong seedling medium for strong seedling culture, and form tissue culture seedlings after 2-3 weeks of cultivation, the strong seedling medium adopts 1L mother liquor and 20mL0.01 concentration The NAA composition;

[0075] S4, rooting culture, the tissue culture seedling is inoculated on the rooting medium and is cultivated to form the ...

Abstract

The invention relates to the technical field of plant seedling culture, and discloses a North America redwood culture medium and a culture method of the North America redwood. Through modification onan enrichment culture medium and a rooting medium and improvement on a disinfection method, the growing efficiency of enrichment culture can be improved through the enrichment culture medium in the culture process of the North America redwood, the rooting effect is improved through the rooting medium, through improvement on the disinfection method, the probability that the North America redwood isinfected by outside impurities in the culture process is decreased, and ultimately the purpose of increasing the survival rate is achieved.

Description
