Embodiment 1

[0018] Fresh and ripe fruits were collected in mid-October. The fruits were wrapped in wet paper towels with a relative humidity of 70% and placed in a closed container under dark indoor conditions for post-ripening treatment for 4 days, and then shelled to obtain seeds, with a mass fraction of Soak the seeds in a 0.1% potassium permanganate solution for 2 hours and dry them in the shade for later use. Spray the substrate with dixon solution diluted 2000 times, leave it for 3 days, pour clear water on the 4th day, and then count the seeds by quartering, spread the soaked seeds in the substrate, and cover a 1.8m above the substrate. The layer of shading net with a shading rate of 90% is watered or sprayed for moisturizing every day; the composition and mass ratio of the substrate are: ceramsite: perlite: vermiculite: river sand: peat soil = 1:2:2 :2:4; the germination temperature of seeds is 10~29℃.

[0019] The germination begins after 50 days, and the germination rate reaches 9...

Embodiment 2

[0021] Collect fresh and ripe fruits in mid-October, wrap them in wet paper towels with a relative humidity of 90%, put them in an airtight container under dark indoor conditions for post-ripening treatment for 5 days, and then husk to obtain seeds, with a mass fraction of 0.3 Soak the seeds in% potassium permanganate solution for 2 hours and dry them in the shade for later use. Spray the substrate with dixon solution diluted 3000 times, leave it for 3 days, pour clear water on the 4th day, and then count the seeds by quarters. Sprinkle the soaked seeds on the substrate, covering a 2m above the substrate. The layer of shading net with a shading rate of 90% is watered or sprayed for moisturizing every day; the composition and mass ratio of the substrate are: ceramsite: perlite: vermiculite: river sand: peat soil = 1:2:2 :2:4; the germination temperature of seeds is 10~29℃.

[0022] The germination began after 45 days, and the germination rate reached 91% after 4 months. Basicall...

Embodiment 3

[0024] Collect fresh and ripe fruits in mid-October, place the fruits at room temperature and ventilate without post-ripening treatment, then hull them to obtain seeds, soak the seeds with 0.2% potassium permanganate solution for 2 hours, then sow after drying in the shade For the processed substrate. Three days before picking the fruit, spray the substrate with dixon solution diluted 2500 times, pour clear water on the 4th day, and then count the seeds by quarters. Sprinkle the soaked seeds in the substrate, 2 meters above the substrate Cover a layer of shading net with a shading rate of 90%, and water or spray moisturize every day; the composition and mass ratio of the substrate: ceramsite: perlite: vermiculite: river sand: peat soil = 1:2 :2:2:4; the germination temperature of seeds is 10~29℃.

[0025] The germination begins after 40 days, and the germination rate reaches 70% after 4 months.

Abstract

The invention discloses a method for seed germination and seedling culture of tutcheria microcarpa. The method comprises the following steps: (1) collecting fresh and ripe fruits and covering the fruits by using a wet tissue with the relative humidity of 70%-90%; placing the fruits into a closed container and carrying out after-ripening treatment under an indoor dark condition; then shucking to obtain seeds; immersing the seeds by using a potassium permanganate solution with the mass percentage of 0.1%-0.3%; and drying in the shade for future use; and (2) spraying a fenaminosulf solution which is diluted for 2,000-3,000 times on a base material and standing for three days; watering clean water thoroughly on the fourth day; scattering the immersed seeds into the base material and covering the base material with a layer of a shading net; and watering or spraying every day for preserving moisture, wherein the base material comprises the following components in mass ratio of ceramsite to perlite to vermiculite to river sand to peat soil being 1 to 2 to 2 to 2 to 4 and the seed germination temperature is 10-29 DEG C. According to the method, the emergence rate of the tutcheria microcarpa is improved through the after-ripening treatment and dormancy breaking, so that the seedling culture needed by artificial cultivation is achieved and artificial cultivation breeding can be carried out by seeding.

Description

Technical field: [0001] The invention belongs to the technical field of plant propagation, and in particular relates to a method for seed germination and seedling cultivation of Astragalus spp. Background technique: [0002] Tutcheria microcarpa Dunn is an evergreen tree in the genus Tutcheria Dunn of the Camellia family Theaceae. It is distributed in Hainan, Fujian, Hunan, Jiangxi, Zhejiang, Yunnan and other places in mainland China. 5-17 meters high. The plant shape is beautiful, the leaves are bright, the shape and size of the leaves, and the size of the flowers vary greatly. The fruit grows densely on the branches. It is a new and excellent woody flower plant that can be used in courtyards, residential areas, squares, and parks. Or street greening, T. spectabilis Dunn, a plant of the same genus, has a strong ability to resist pollution (fluoride, sulfide and acid rain). Lithospermum gracilis is also a potential bio-energy plant, and its seed oil content of Lithospermum in t...
