Description

Technical Field

[0001] The invention relates to the technical field of seed rehydration, in particular to a device and method for rehydrating deciduous Manglietia seeds and improving the survival rate. Background Art

[0002] Deciduous Magnolia is an evergreen tree in the Magnoliaceae family and genus Magnolia, reaching up to 30 meters tall with a straight trunk. Its leaves are elliptical, oblong, or obovate, with entire margins. Its solitary, bisexual, pale yellow flowers are borne at the tops of branches. Its tepals are three equal and nearly leathery in a whorl. Its anthers are linear, with short, inconspicuous filaments. Its aggregate fruit is dense and contains several seeds.

[0003] Deciduous Magnolia propagates primarily through seed, but its storage period is short. Naturally dried and stored Magnolia seeds have a low germination rate, and the survival rate of germinating seedlings is also low, hindering the conservation of endangered plants. Ultra-drying (drying to a moisture content below 5%) is an effective method for extending the storage period and improving the germination rate of deciduous Magnolia seeds. However, ultra-dried seeds require rehydration before germination. Conventional pure water immersion methods, due to the zero water potential of pure water, can easily cause seed cells to tear and rupture, thereby affecting seed germination and seedling survival rates. Existing seed rehydration devices, which typically utilize simple water containers, also suffer from the following drawbacks: First, a low degree of automation requires manual, periodic scooping of seeds and filtering out residual moisture, resulting in very low efficiency; and second, seeds tend to float on the water surface, leading to uneven immersion.

[0013] A method for rehydrating deciduous Manglietia seeds and improving their survival rate, comprising the steps of: preparing a seed soaking solution; soaking and rehydrating the seeds; centrifuging and drying; and automatically discharging the seeds;

[0014] In the above step 1, PEG gradient concentration solutions (30%, 20%, 15%, 10% and 5%) are prepared in the liquid preparation tank in sequence, and the prepared solutions are transported to the water storage tanks of the corresponding stations via water pumps and electric valves;

[0015] In the above step 2, the first telescopic rod is extended, so that the spring flap on the top of the filter cartridge reaches the open position, the second telescopic rod at the feeding position is retracted, and the first retractor is pulled by the second retractor to open the spring flap, and the deciduous Magnolia seeds are transported to the feeding pipe by the vacuum feeder, and then fall into the filter cartridge, and then the second telescopic rod is extended and reset, the spring flap is closed, and the motor rotates one station, so that the filter cartridge at the feeding position is transferred to the first water storage tank, and then the first telescopic rod is retracted, so that the filter cartridge descends into the water storage tank, and the seeds are soaked in the 30% concentration solution;

[0016] In the above step 3, after soaking for one hour, the first telescopic rod is extended, and the filter cartridge at the feeding position is loaded according to the method in step 2. Then the motor rotates for a set time, and the residual solution in the filter cartridge is thrown onto the inner wall of the tank under the action of centrifugal force, and discharged from the tank through the water collection tank and the drain pipe.

[0018] Preferably, in step 2, a torsion spring is provided at the hinge between the spring flap and the filter cartridge, and the spring flap is automatically kept in a closed state by the elastic force provided by the torsion spring.

[0019] Compared with the prior art, the characteristics and beneficial effects of the present invention are:

[0020] Through extensive testing, a method for rehydrating ultra-dried deciduous Magnolia seeds and improving their survival rate has been developed. Controlling the rehydration rate within the 45%-55% range is most beneficial for seed germination and seedling survival.
