Problems solved by technology

[0002] Bracken is a perennial herb that grows in mixed coniferous and broad-leaved forests or in the gaps between broad-leaved forests and grassy hills. The effect of calming nerves and diuresis is favored by people for its unique flavor and rich nutrition. Using a large number of spores produced by bracken for artificial propagation is an effective way to improve the reproductive coefficient of bracken. At present, the technology of raising bracken spores mainly exists The shortcoming of long period and low seedling rate

Embodiment Construction

[0011] In July, select the uncracked sporangia group of tan sporangia, cut off the leaves with spores, place them in a ventilated place to dry naturally, collect scattered spores, collect and place them in refrigerated environment at 4°C; , urea-formaldehyde foam, pine needle soil, bone meal, silicate bacterial fertilizer, kinetin, betaine, spermidine, inositol residue, vitamin B1, vitamin B2, according to 10:1:5:0.5:0.5:0.005:0.1 :0.0001:0.3:0.008: 0.03 weight ratio, mixed evenly, sterilized at 110°C for 10 minutes to make a culture medium; after fully washing the bracken spores with sterile water, put them in at a concentration of 1.5mg / L of zeatin and a concentration of 15 mg / L of naphthalene acetic acid mixed solution soaked for 18 minutes, sowed in the culture medium, evenly sowed 9 bracken spores per square meter; during the growth period of the bracken spores, keep the growth humidity at 82%, and the growth The temperature was kept at 26° C., and the growth light inten...

Abstract

The invention relates to a fiddlehead spore seedling nursing technology. Uncracked sporangium groups in a dark brown color are selected; leaves having spores are cut down and placed in a ventilating position for natural drying; scattered spores are collected and refrigerated at the temperature of 4 DEG C; reed powder, urea formaldehyde foamed plastic, pine needle soil, bone meal, silicate bacterial fertilizer, kinetin, betaine, spermidine, inositol, vitamin B1 and vitamin B2 are mixed to form culturing substrate; the fiddlehead spores are fully flushed via sterile water, and then immersed into a mixed solution formed by zeatin and naphthylacetic acid with growth humidity remained around 82% to 85%, growth temperature of 26 to 26.5 DEG C and illumination strength of 1800 to 20001x; and when the spore infant seedling grows to 6cm, the fiddlehead spore infant seedlings on the culturing substrate are thinned. The fiddlehead spore seedling nursing technology is advantaged by high stability, strong controllability and great operability; seedling nursing period of the fiddlehead spores can be shortened; and seedling rate and rooting rate can be enhanced.

Description

technical field [0001] The invention relates to a method for cultivating wild vegetables, in particular to a technique for cultivating bracken spores. Background technique [0002] Bracken is a perennial herb that grows in mixed coniferous and broad-leaved forests or in the gaps between broad-leaved forests and grassy hills. The effect of calming nerves and diuresis is favored by people for its unique flavor and rich nutrition. Using a large number of spores produced by bracken for artificial propagation is an effective way to improve the reproductive coefficient of bracken. At present, the technology of raising bracken spores mainly exists The disadvantages of long period and low seedling rate. Contents of the invention [0003] The object of the invention is to provide a bracken spore seedling raising technology which shortens the seedling raising period and improves the seedling rate. [0004] The technical scheme that the present invention adopts is, a kind of bracke...
