Description
Technical Field
[0001] This utility model relates to the field of medicinal herb seedling cultivation, specifically to a seedling bed for medicinal herb cultivation. Background Technology
[0002] Seedling cultivation is a crucial step in medicinal herb planting, as its quality directly determines the growth, active ingredient content, and yield of mature plants. Currently, most medicinal herb seedbeds utilize traditional flat beds or simple raised platforms, which present the following key problems: Low precision in temperature and humidity control: Traditional seedbeds rely on the natural environment or simple covering film to control temperature, which cannot be dynamically adjusted according to the temperature and humidity requirements of different stages of medicinal seedling cultivation (germination period, seedling period, hardening period), which easily leads to seed rot due to low temperature, excessive growth due to high temperature, or diseases caused by excessive humidity (such as root rot). The contradiction between substrate permeability and water retention: To ensure water retention, a closed upper structure is often used, resulting in poor substrate permeability. Root and rhizome medicinal materials (such as Astragalus membranaceus) are prone to root hypoxia. If permeability is increased, frequent watering is required, which increases labor costs and can easily lead to uneven watering. Poor transplanting convenience: Most existing seedbeds are laid with an integral substrate. When transplanting, seedlings need to be manually separated from the substrate, which can easily damage the root system and reduce the transplant survival rate. This is especially unsuitable for dense seedling cultivation scenarios. Water and substrate waste: Excess water is lost directly during watering without being recycled, and the substrate needs to be cleaned up when it is replaced. The residual substrate is prone to breeding bacteria, which affects the quality of seedlings in the next season. Utility Model Content
[0003] To address the aforementioned shortcomings of existing technologies, this utility model provides a seedling bed for medicinal herb cultivation that integrates temperature control, moisture retention, ventilation, circulation, and transplanting.
[0004] To achieve the above-mentioned objectives, the technical solution adopted by this utility model is as follows: A seedling bed for medicinal herb cultivation is provided, comprising a seedling bed body, a seedling box at the upper end of the seedling bed body, the seedling box having an open upper end and a V-shaped bottom, the seedling box being filled with an absorbent cotton layer, the seedling box being divided into several seedling channels by partitions, each seedling channel having a support for placing seedling cups, the support having several through holes evenly spaced; a strip-shaped drain outlet is provided on the bottom surface of the seedling box, a filter layer is provided below the drain outlet, a water tank with an open upper end is provided at the lower end of the filter layer, the water tank is connected to a water pump, the water pump drains water into the seedling channels through a drain pipe, a temperature control component is provided at the bottom of the seedling box, and both the temperature control component and the water pump are electrically connected to a controller.
[0005] Furthermore, the water pump is connected to the water tank through the inlet pipe, and each seedling channel is connected to a branch water pipe on its side. The branch water pipe is connected to the drain pipe, and an electromagnetic water valve is installed at the connection between the branch water pipe and the drain pipe. The electromagnetic water valve is electrically connected to the controller.
[0006] Furthermore, the filter layer includes a filter box with an opening at the top and a water filtration hole at the bottom. The filter box is fixed on the seedling bed body, and a quartz sand layer and an activated carbon layer are arranged in sequence from top to bottom inside the filter box.
[0007] Furthermore, the upper end of the seedling bed body is provided with several frames, the two ends of which are respectively set on both sides of the upper end of the seedling bed body. T-shaped sliders are set at both ends of the frames, and T-shaped grooves are set on both sides of the upper end of the seedling bed body.

[0008] Furthermore, each seedling channel is equipped with a temperature and humidity sensor on its support frame. The sensor probe extends into the absorbent cotton layer and is electrically connected to the controller.
[0009] The beneficial effects of this utility model are: This invention enables real-time temperature and humidity monitoring and control during the medicinal herb seedling cultivation process. The absorbent cotton layer ensures good water absorption while also providing excellent air permeability, preventing excessive water accumulation in the seedling channel. Excess water is drained through the drain outlet via the absorbent cotton layer, meeting the basic humidity requirements for medicinal herb seedling cultivation without wasting water. Excess water is filtered and then recycled into a water tank. The independent seedling cup design provides seedlings with their own independent growth space. During transplanting, the seedlings can be directly removed from the cup, effectively reducing root damage and increasing transplant survival rate. Furthermore, the seedling cups are reusable, minimizing substrate waste.
[0010] This invention overcomes the shortcomings of existing medicinal herb seedling beds, such as low temperature and humidity control precision, contradiction between substrate permeability and water retention, inconvenient transplanting, and resource waste. It designs a medicinal herb planting seedling bed that can meet the needs of each stage of medicinal herb seedling cultivation, improve seedling quality and transplant survival rate, and realize resource recycling.

By controlling the opening degree of the electromagnetic water valve 15, the amount of water discharged into the seedling channel can be regulated, thereby controlling the humidity of the growth environment for the medicinal herb seedlings. The electromagnetic water valve 15 is an AC220V 2W-160-15 type normally closed electromagnetic water valve.
[0021] The filter layer includes a filter box 4 with an opening at the top and filter holes at the bottom. The filter box 4 is fixed to the seedling bed body. Inside the filter box 4, from top to bottom, there are a quartz sand layer 12 and an activated carbon layer 13. The filter layer is 6cm thick (4cm of quartz sand and 2cm of activated carbon). The drainage holes on the bottom plate of the filter box 4 are 6mm in diameter and spaced 12cm apart. A support mesh is installed inside the filter box 4 to support the quartz sand layer 12 and the activated carbon layer 13.

One side of each T-shaped groove 16 is open, and the T-shaped slider 8 is inserted and slidably positioned within the T-shaped groove 16 through the opening on one side. A sunshade can be constructed using the frames 7 to regulate light intensity. When not in use, the frames can be directly pulled out from the opening, making installation and disassembly convenient.
[0023] In this embodiment, a temperature and humidity sensor 11 is installed on the support 14 in each seedling channel. The probe of the temperature and humidity sensor 11 extends into the absorbent cotton layer, and the temperature and humidity sensor 11 is electrically connected to the controller 10. The controller 10 in this embodiment includes a control box installed on the side of the seedling bed body. The control box contains a PCB control board equipped with a C51 microcontroller, and a screen is provided on the control box to display seedling status data. The temperature and humidity sensor 11 is a DHT11 type temperature and humidity sensor.
