Problems solved by technology

At the same time, because the wild vegetables produced naturally cannot meet people's needs, people use the method of digging roots to propagate seedlings for artificial cultivation, which further aggravates the destruction of resources.

Embodiment 1

[0027] (1) Using bracken spores as raw materials, soak the spores in pure water for 4 hours, soak them in 85vt% alcohol for 10 seconds, rinse them with sterile water for 3 times, place them in a culture vessel filled with nutrient solution, and make the nutrient solution The spores are infiltrated with the liquid, the incubator is placed in an environment of 25° C. and a humidity of 70%, cultivated for 50 hours, the spores germinate, and are cut off when the buds grow to 1 cm; the growth-promoting nutrient solution has the following mass percentages: Moisture 97.6%, citric acid 1%, glycerin 1%, ferrous sulfate 0.4%;

[0028] (2) Use the buds obtained in step (1) as explants, clean them with sterile water, soak them in 75vt% alcohol for 10 seconds, rinse them with sterile water for 3 times, and then use 0.1vt% liters of Soak in mercury for 5 minutes, rinse 5 times with sterile water;

[0029] (3) Insert the buds after disinfection and cleaning in step (2) into the bud inductio...

Embodiment 2

[0039] (1) Using bracken spores as raw materials, soak the spores in pure water for 4 hours, soak them in 85vt% alcohol for 10 seconds, rinse them with sterile water for 5 times, place them in a culture vessel filled with nutrient solution, and make the nutrient solution The spores are infiltrated with the liquid, the incubator is placed in an environment of 25° C. and a humidity of 70%, cultivated for 50 hours, the spores germinate, and are cut off when the buds grow to 1 cm; the growth-promoting nutrient solution has the following mass percentages: Moisture 97.6%, citric acid 1%, glycerin 1%, ferrous sulfate 0.4%;

[0040] (2) Use the buds obtained in step (1) as explants, clean them with sterile water, soak them in 75vt% alcohol for 10 seconds, rinse them with sterile water for 5 times, and then use 0.1vt% liters of Soak in mercury for 5 minutes, rinse 5 times with sterile water;

Embodiment 3

[0051] The cultivation method and the raw materials and parameters used in this embodiment are the same as those in Embodiment 2, the only difference being that no ultraviolet irradiation is carried out after acclimation in step (5).

Abstract

The invention relates to a hill potherb cultivation method, particularly to a method for high-yield cultivation of pteridium aquilinum var.latiusculum on mountain, and belongs to the technical field of rapid plant breeding. The technical scheme of the invention mainly comprises: growing bud by using spore as a raw material, washing and disinfecting explants, culturing clustered shoots, carrying out stem separating culture on the clustered shoots, acclimatizing tissue culture seedling, transplanting, and spraying a selenium-rich nutrition solution. According to the present invention, the problems that the seedling source is short, the seedling exercising survival rate and the transplanting survival rate are low, the yield is not high, and the like during the large-area artificial cultivation of the pteridium aquilinum var.latiusculum are saved; and with the high-yield cultivation method, the seedling propagation rate is increased by hundreds of times, the seedling exercising survival rate and the transplanting survival rate are increased to more than 97%, the yield is increased to more than 34%, the powerful assurance is provided for the promotion of the large-scale development of the pteridium aquilinum var.latiusculum industry as soon as possible, and the good social and economic benefits are provided.

Description

technical field [0001] The invention relates to a method for cultivating wild vegetables, in particular to a method for cultivating bracken with high yield in mountain areas. Background technique [0002] With the improvement of people's living standards and health standards, people pay more and more attention to the nutritional value and therapeutic value of food. Green food is very popular among people, and wild vegetables are one of them. Mountain wild vegetables not only have high edible value, but also have certain medical and health care value. In my country, edible wild vegetables have a history of thousands of years. Wild vegetable food is pollution-free, pollution-free and safe to eat. Edible mountain wild vegetables are used as a supplement source of vitamins and macro or trace elements, which increases nutrition and is beneficial to health. [0003] Bracken, also known as fist vegetable, cat's claw, and dragon head vegetable, is a perennial fern. Because brack...
