Embodiment 1

[0030] A method for seed germination of Sirindhorn Michelle, comprising the following steps:

[0031] 1. Prepare species.

[0032] During September-November when the seeds are ripe, when the spike-shaped follicles of Sirindhorn Michelia turn from yellow-green to reddish-brown or yellow-brown, and the follicles have not cracked or a small amount of cracks reveal bright red seeds, harvest the bright red Put the follicles in a cool, ventilated place without direct sunlight, and wait for the follicles to crack naturally and the seeds to come out naturally, and you will get Sirindhorn Michelia Seeds.

[0033] Harvesting too early or too late will affect the germination rate. Harvesting too late will also cause seed loss due to follicle cracking or animal predation, reducing the amount of seed harvest.

[0034] Second, remove the oil film.

[0035]Put the seeds in a ventilated place without direct sunlight. After the seeds are harvested, the outer testa turns black and the seeds b...

Embodiment 2

[0056] A method for raising seedlings of Sirindhorn with a smile, comprising the following steps:

[0057] One, adopt the method of embodiment 1 to make Sirindhorn michelia seeds germinate.

[0058] 2. Move the germinated Sirindhorn Michelia seed buds to an outdoor shade shed. The shading degree of the shade shed is 75%, and the height is 1.8-2.0 meters. Keep ventilation and temperature ≥ 5°C for seedling cultivation.

[0059] When the temperature is lower than 5°C, the awning should be covered with plastic film to prevent cold. When there is sunlight during the day, part of the film should be uncovered for ventilation, and then covered at night to keep warm.

[0060] 3. After the seedlings grow to 5-6cm, transplant the sprouts, transplant the seedlings into the predetermined seedling bags, and place them in the same shade shed for cultivation.

[0061] Four, keep moist in the seedling-raising bag, drench nutrient solution every 15 days after 1-2 months, described nutrient so...

Embodiment 3

[0064] A kind of method of Sirindhorn Michelia seed germination is basically the same as the method of embodiment 1, the difference is:

[0065] 3. Seed soaking.

[0066] Soak the above-mentioned seeds after removing the oil film in water at 55°C for 5 minutes, then stir until the water temperature drops to 30°C, and place at room temperature to continue soaking the seeds for 36 hours.

Abstract

The invention relates to a magnolia sirindhorniae seed germination and seedling cultivation method and belongs to the technical field of plant breeding. The method comprises the steps of oil slick removal, wherein seeds are cleaned with an alkaline solution after arils are removed, so that oil slicks outside are removed; seed soaking, wherein based on the variable-temperature seed soaking method, the seeds with the oil slicks removed are soaked in water which is 45-60 DEG C for 2-8 min, and then indoor-temperature seed soaking is conducted for 26-46 h after the temperature of water is lowered to indoor temperature; disinfection and dormancy breaking, wherein the seeds are disinfected with a disinfectant and then soaked in gibberellin for 36-60 h; germination accelerating, wherein the seeds are treated under light for 14-18 h and in dark for 6-10 h alternately in an environment with a relative humidity of 80-95% till the seeds are revealed; sowing, wherein the revealed seeds are sown in a fertilized matrix and cultivated to germinate. By the adoption of the method, the germination rate of the magnolia sirindhorniae seeds can be increased to over 50% from around 20%.

Description

technical field [0001] The invention relates to the technical field of plant breeding, in particular to a method for seed germination and seedling cultivation of Sirindhorn michelia. Background technique [0002] Sirindhorn smiles, and its scientific name is Micheliasirindhorniae (Noot. et Chal.) N.H.XiaetX.H.Zhangj. At present, Sirindhorniae Noot. & Chalermglin is commonly used in the world for naming. This tree species is one of the critically endangered and rare tree species in the world. Its leaves and flowers are very aromatic and can be used to extract valuable natural plant essences. [0003] Sirindhorn Smile, native to Thailand, is an evergreen tree of Magnoliaceae, with a straight trunk and a height of 30-35m. The leaves are oval, and both sides of the young leaves are densely covered with brown puberulent hairs; the flowers are solitary in the leaf axils near the top of the branches, with 12-18 tepals, and a single flower can bloom for 2-3 days, and the flowering...
