Embodiment 1

[0061] The seed germination experiment of embodiment 1 cuckoo red camellia

[0062] (1) Seed collection and net planting;

[0063] Seed collection: Collected from March to May, the fruit turns from green to brown, the capsule has just cracked, the fruit is collected back, and it is naturally stacked and retting indoors for 2 to 3 days. When the fruit is completely cracked, the seeds are taken out.

[0064] Net planting: Put the collected Rhododendron red camellia seeds into the seed blower (CFY-Ⅱ) for net planting, adjust the wind speed to 18 meters per second, and keep blowing for 2 minutes. Fly out, the reserved seeds are good seeds, if attached figure 1 shown.

[0065] (2) Sterilization treatment: the fine seeds (thousand-grain weight about 325g) after cleaning are sterilized and cleaned in 800-1000 times aqueous solution of carbendazim, and dried in the air.

[0066] (3) Gibberellin aqueous solution treatment: soak the dried seeds in 2000 times aqueous solution of 3% gi...

Abstract

The invention relates to a seed germination method and seedling raising method of rhododendron red camellia. The seed germination method comprises the following steps: (1) collecting seeds and planting them cleanly; (2) sterilizing treatment; (3) treating with gibberellin aqueous solution; soaking the treated seeds in step (2) with gibberellin solution, taking out (4) sowing seedbed construction: the seedbed matrix is ​​made up of yellow heart soil and burnt soil, after the seedbed matrix is ​​sterilized, prepare the sowing seedbed; (5) sow; (6) seedbed management: keep the water content of the seedbed matrix as 25-35 %, control pests. The seedling raising method comprises the following steps: (A) the seeds of the above method grow into seedlings after germination, and the seedlings are watered and then planted in a seedling raising matrix, the seedling raising matrix is ​​composed of yellow core soil and perlite, and watering is performed again after planting; (B) seedlings manage. The method of the invention can significantly improve the seed germination rate and planting survival rate of the rhododendron red camellia, and shorten the cultivation period of the rhododendron red camellia plant.

Description

technical field [0001] The invention relates to the field of plant planting, in particular to a seed germination and seedling raising method of rhododendron red camellia. Background technique [0002] Camellia azalea, also known as Four Seasons Camellia, is an evergreen shrub of Theaceae Camellia, up to 4 meters high, with red twigs, glabrous, and gray old twigs. Simple leaves, alternate or nearly whorled, often clustered at the top of branchlets, leathery, narrowly obovate or oblanceolate, 5.5-12 cm long, 2-4 cm wide, rounded at the apex, cuneate at the base, dark green above, below Light green, entire, with a translucent narrow border, thick midrib, convex on both sides, slender lateral veins; petiole 6-15 mm long, glabrous. Flowers are bisexual, solitary, or 2 to 5 clustered at the top of branchlets, with a flower diameter of more than 10 cm; petals are bright red, arranged in 6 to 9 imbricate tiles, oblanceolate, 4.5 to 8 cm long, 2.5 to 2.5 cm wide 4.5 cm, apex deeply...
