[0022] To help those skilled in the art better understand the present invention, the following will provide a clear and complete description of the technical solutions in the embodiments of the present invention, in conjunction with the accompanying drawings. It is clear that the embodiments described are only part of the embodiments of the present invention, not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative work should fall within the scope of protection of the present invention.

[0023] The terms "first," "second," "third," and the like in the specification and claims of this application and the accompanying drawings are used to distinguish between different objects, not to describe a particular order. Furthermore, the terms "including," "having," and any variations thereof, are intended to cover non-exclusive inclusions. For example, a process, method, system, product, or apparatus comprising a series of steps or elements is not limited to the listed steps or elements, but may optionally include steps or elements not listed, or may optionally include other steps or elements inherent to the process, method, product, or apparatus.

[0024] The following describes the embodiments in detail.

[0025] Many experiments have confirmed that magnetic fields have many positive effects on plant seed germination and growth, as follows.

[0026] (1) Impact on seed germination process

[0027] 1. Improved germination rate: Appropriate magnetic field treatment can activate enzyme systems within seeds. For example, in legume seeds, magnetic fields can enhance the activity of respiratory enzymes and other enzymes within seed cells. These enzymes play a key role in seed germination, accelerating the breakdown and conversion of nutrients within the seed. Increased amylase activity accelerates the breakdown of stored starch into soluble sugars, providing the energy and material foundation for seed germination and ultimately improving seed germination rates.

[0028] 2. Accelerate germination: Magnetic fields can alter the distribution of ions within seed cells. Normally, potassium and calcium ions are present within seed cells. Under the influence of a magnetic field, the migration and distribution of these ions change, in turn altering the permeability of the cell membrane. This allows cells to absorb water and nutrients more rapidly, accelerating the seed's imbibition process. For example, wheat seeds treated with a magnetic field absorb water significantly faster than untreated seeds, and this, in turn, accelerates seed germination.

[0029] (2) Impact on seedling growth

[0030] 1. Promote root growth: Magnetic fields can stimulate cell division in the root apex meristem of plants. The root apex is a key site for plant root growth, and magnetic fields can influence the assembly and arrangement of the cytoskeleton, including microtubules and microfilaments, within cells. The cytoskeleton supports and guides cell division and elongation. For example, in corn seedlings, magnetic field treatment increased the frequency of cell division in root apex cells, and the length and number of root hairs also increased. This increase in root hairs helps plant roots more efficiently absorb water and mineral nutrients from the soil, thereby promoting the growth of the entire root system.

[0031] 2. Promote stem growth and development: Magnetic fields can regulate the distribution of plant hormones, thereby affecting plant stem growth. Auxin plays a crucial role in stem growth. Magnetic fields can influence the polar transport of auxin, improving its distribution within the elongation zone of the stem. For example, in pea seedlings, after magnetic field treatment, auxin concentration in the elongation zone of the stem increases, stimulating cell elongation and increasing stem length. Furthermore, magnetic fields can enhance the thickening of the secondary walls of stem cells, thereby increasing the mechanical strength of the stem and helping the plant better support its growth.

[0032] (3) Impact on other plant physiological and biochemical processes

[0033] 1. In terms of photosynthesis: Magnetic fields can affect the structure and function of chloroplasts in plant leaves. Chloroplasts are the site of photosynthesis in plants. Magnetic fields can make the thylakoid structure within chloroplasts more compact, facilitating the absorption and conversion of light energy. Magnetic fields can also promote the synthesis of chlorophyll, a key pigment that absorbs light energy during photosynthesis. For example, after magnetic field treatment, the chlorophyll content in tomato seedlings increased, improving photosynthesis efficiency and providing more organic matter for plant growth.

[0034] 2. Antioxidant systems: Plants are subject to various stresses during growth, producing large amounts of reactive oxygen species (ROS). Magnetic fields can enhance the activity of antioxidant enzymes within plant cells, such as superoxide dismutase (SOD) and catalase (CAT). These antioxidant enzymes can scavenge intracellular ROS and reduce oxidative damage. For example, when subjected to drought stress, after germination, seedlings pretreated with magnetic fields exhibited higher antioxidant enzyme activity and less oxidative damage than untreated seedlings, helping plants better adapt to adverse environments.

[0035] In addition, the rotating magnetic field also has many effects on the germination and growth of plant seeds:

[0036] (1) Impact on seed germination

[0037] 1. Promote seed germination: Rotating magnetic fields can increase seed germination rate and germination potential. For example, when wheat seeds were treated with an 11mT rotating magnetic field for 30 minutes, their germination rate and germination potential increased by 7.37% and 8.24%, respectively, compared to the control. Rotating magnetic fields can also accelerate water absorption by the seed's endosperm and the elongation of the embryonic axis, thereby promoting faster seed germination.

[0038] (2) Impact on seedling growth

[0039] 1. Enhanced Seedling Growth: After treatment with a rotating magnetic field, wheat seedlings showed significant increases in growth indicators such as plant height, root length, and root number. For example, wheat seedlings treated for 30 minutes showed an 11.13% increase in plant height, and significantly higher root length and number than the control. Furthermore, treatment with a rotating magnetic field significantly increased biomass accumulation in wheat seedlings, with varying treatment times demonstrating varying effects. A 20-minute treatment had the greatest impact on biomass accumulation in seedlings.

[0040] (3) Impact on other physiological and biochemical processes

[0041] 1. Regulating enzyme activity: Rotating magnetic fields can affect the activity of enzymes in seeds and seedlings, such as peroxidase and polyphenol oxidase. These enzymes play an important role in seed germination and seedling growth. Increased activity helps accelerate the transformation and metabolism of substances in seeds.

[0042] 2. Impact on hormone balance: Rotating magnetic fields may regulate seed germination and seedling growth by affecting the synthesis and transport of endogenous plant hormones. For example, electromagnetic field treatment can change the levels of IAA and ABA in winter wheat seeds, thereby affecting seed germination dynamics and early growth.

[0043] 3. Enhanced stress resistance: Seeds treated with a rotating magnetic field show stronger stress resistance during growth and can better adapt to adverse environmental conditions such as drought and low temperature.

[0044] In summary, magnetic fields have a significant promoting effect on plant seed germination and growth, and play a role in multiple physiological and biochemical processes, helping to improve plant growth quality and stress resistance.

[0045] Based on the above principles, the present application proposes a magnetically assisted germination and growth nursery bed.

[0046] refer to Figure 1 The present application proposes a magnetic-assisted germination and growth nursery bed, comprising:

[0047] The upper seedling bed 11 is used to accommodate the seedling substrate and plant seeds or seedlings;

[0048] The lower magnetic treatment layer 12 is arranged just below the upper seedling bed and has a built-in magnetic treatment device;

[0049] The magnetic processor is configured to provide a magnetic field to the upper seedling bed to promote seed germination or seedling growth.

[0050] Here, the upper seedling bed 11 can adopt various conventional seedling beds, and this application is not limited thereto.

[0051] Here, the magnetic processor in the lower magnetic processing layer 12 can adopt various structural forms, and three optional forms are provided below.

[0052] (1) Permanent ferrite module

[0053] In some optional embodiments, the magnetic processor includes a permanent ferrite module. The permanent ferrite module is a permanent magnet module made of ferrite material. Ferrite material is not easily demagnetized after magnetization and can retain its magnetism for a long time. It is a permanent magnet material or a constant magnet material.

[0054] When using a permanent ferrite module, its shape can be diverse, including at least one of a disc, a cylinder, a drum, or an annular shape. It can be magnetized using radial magnetization (i.e., the magnetic field direction is the same as the radial direction) or axial magnetization (i.e., the magnetic field direction is the same as the axial direction). After magnetization, the module is encapsulated with a waterproof material to prevent moisture erosion and ensure long-term stability of the magnet performance. The waterproof material can be, for example, a plastic waterproof material.

[0055] Here, the intensity of the magnetic field generated by the permanent ferrite module may range from 50 mT to 500 mT.

[0056] (2) Halbach magnetic array module

[0057] In some optional embodiments, the magnetic processor includes a Halbach magnetic array module. A Halbach magnetic array is a magnet structure that is an approximately ideal structure in engineering, and its goal is to generate the strongest magnetic field with the least amount of magnets.

[0058] If a Halbach magnetic array module is used, it can be assembled from multiple permanent magnets in a Halbach structure, either in a linear array or a planar array. This module can form a unique, single-sided, strong magnetic field surface, providing a high-intensity magnetic field for the aquarium. The module is also encapsulated in a waterproof material (such as plastic waterproof material) to prevent moisture erosion and ensure long-term stability of the magnetic performance. The waterproof material can be, for example, plastic waterproof material.

[0059] Here, the intensity of the magnetic field generated by the Halbach magnetic array module may range from 100 mT to 500 mT, and the strong magnetic field surface of the Halbach magnetic array module faces the upper seedling bed.

[0060] (3) Gyromagnetic generator

[0061] In some alternative embodiments, the magnetic processor comprises a gyromagnetic generator.

[0062] The gyromagnetic generator can be a gyromagnetic generator that uses a single-phase AC gyromagnetic method. The gyromagnetic generator can include four horizontally arranged coil windings, which are divided into two groups. The first group consists of two coil windings placed in parallel front and back. The two coil windings have the same winding direction and are connected in parallel. They are directly connected to the AC power supply to ensure stable current input; the second group consists of two coil windings placed in parallel left and right. They are also connected in parallel, but when connected to the AC power supply, they are connected through a series capacitor or resistor, so that the input signal is phase-shifted. When the two groups of coil windings are fed with AC power with a phase difference, a rotating magnetic field can be generated within the range of the upper seedling bed 11.

[0063] Here, the magnetic field strength of the rotating magnetic field can be controlled between 5 mT and 500 mT.

[0064] The magnetic processor is described in detail above. Specifically, different types of magnetic processors and different magnetic field strengths can be used according to different seedling varieties, the size of the seedling bed, and other conditions.

[0065] In some optional embodiments, the magnetically assisted germination and growth seedling bed of the present application further includes: an adjustable height bracket, which is arranged between the upper seedling bed 11 and the lower magnetic treatment layer 12, and is used to adjust the distance between the two layers to adjust the magnetic field strength.

[0066] In some optional embodiments, the magnetically assisted seedling bed of the present application further includes: a control device connected to the magnetic processor, configured to control the intensity of the magnetic field applied by the magnetic processor within the upper seedling bed according to a preset plant growth rhythm, such that the magnetic field has different intensity values at at least two time periods throughout the day. In this way, the magnetic field can be aligned with the daily physiological rhythm of the plant and enhance the promoting effect of the magnetic field on plant seeds or seedlings.

[0067] In some optional embodiments, to ensure precise control and stable output of magnetic field intensity, the system can further include a monitoring device. The monitoring device is configured to monitor the intensity of the magnetic field within the upper seedling bed in real time and transmit the monitoring data to a control device. The control device is further configured to adjust the magnetic field intensity based on the monitoring data to ensure that the magnetic field remains within a set range, accurately meeting the growth promotion requirements of plant seeds or seedlings.

In the above embodiments, the description of each embodiment has its own focus. For parts not described in detail in one embodiment, please refer to the relevant description of other embodiments.
