Description

Technical Field

[0001] This utility model relates to the field of plant cultivation technology, specifically to a biomimetic circulating cultivation device for cultivating Dendrobium officinale using heat-resistant monostellatium. Background Technology

[0002] Dendrobium officinale is a precious traditional Chinese medicine with extremely demanding requirements for its growing environment (such as humidity, ventilation, and light). Traditional field cultivation methods are greatly constrained by the natural environment, resulting in unstable yields and quality. Existing tissue culture seedling and greenhouse cultivation techniques have solved the environmental control problem to some extent, but the following shortcomings still exist: Inaccurate humidity control: Traditional spraying methods can easily cause water to accumulate on the leaves, leading to diseases; or uneven humidity can cause localized dryness.

[0003] The contradiction between ventilation and humidity: Good ventilation is key to preventing diseases, but it will quickly reduce air humidity, which conflicts with the high humidity requirements of Dendrobium officinale.

[0004] Poor root environment: The substrate for ordinary potted or bed-grown plants has poor internal aeration, which makes the roots prone to rot.

[0005] Low nutrient utilization efficiency: Traditional irrigation or spraying methods result in the loss of a large amount of water and nutrients that are not absorbed by the plants.

[0006] Therefore, there is an urgent need for a cultivation device that can precisely regulate the rhizosphere and canopy environment, achieve efficient water and fertilizer utilization, and simulate its natural growth habits. Utility Model Content

[0007] The purpose of this invention is to address the aforementioned shortcomings by providing a biomimetic circulating culture device for culturing Dendrobium officinale using heat-resistant monostellate algae.

[0008] This utility model relates to a biomimetic circulating culture device for cultivating Dendrobium officinale using heat-resistant single-star algae, comprising: The cultivation chamber 1 is equipped with a cultivation rack 12 and multiple detachable biomimetic cultivation modules 13. The environmental control system includes a set of ultrasonic atomizing nozzles 21 for generating atomized water vapor, a liquid pipe 22 for conveying the liquid concentrate to the set of ultrasonic atomizing nozzles 21, and a circulating ventilation unit for promoting airflow within the cabin. The circulation system 3 includes a nutrient solution tank 31 for storing liquid and a return pipe 32 for recovering unabsorbed liquid back to the nutrient solution tank 31.

[0009] Furthermore, the biomimetic cultivation module 13 includes a hollow cultivation basket 131 and a water collection trough 132 threadedly connected to the bottom of the cultivation basket 131. The bottom of the water collection trough 132 is provided with a return hole that communicates with the return pipe 32.

[0010] Furthermore, the circulating ventilation unit includes a fan disposed on one side wall of the culture chamber 1 and a convection louver 232 disposed on the opposite side wall, which is used to form a low-speed fan (231) in the culture chamber 1 to form a horizontal circulating airflow.

[0011] Furthermore, the environmental control system also includes an LED supplementary lighting unit 24 with adjustable spectrum and light intensity, which is installed on the top of the culture chamber 1.

[0012] Furthermore, it also includes an intelligent control system, which includes a controller, a humidity sensor for monitoring the humidity of the air inside the cabin, and a timer.

[0013] Furthermore, the controller is configured to receive the signal from the humidity sensor and control the ultrasonic atomizing nozzle 21 to perform intermittent start-stop operation.

[0014] Furthermore, the controller is also configured to activate the circulating ventilation unit during the interval when the ultrasonic atomizing nozzle 21 stops operating.

[0015] Furthermore, the liquid pipe 22 is arranged along the cultivation rack 12, and a plurality of ultrasonic atomizing nozzles 21 are provided thereon, with the spray direction of the nozzles facing the cultivation basket 131 area of ​​the biomimetic cultivation module 13.

[0016] Furthermore, the body of the culture chamber 1 is made of transparent material.

[0017] Furthermore, the cultivation basket 131 is made of mesh or perforated plate material.

[0018] Advantages of the utility model: The design of the biomimetic cultivation module simulates the rock or tree trunk environment where Dendrobium officinale grows epiphytically. The hollow cultivation basket greatly improves the aeration of the root system. At the same time, the closed-loop circulation system greatly improves the utilization rate of water and nutrients, reducing water and fertilizer waste by more than 90%.

Those skilled in the art can understand the specific meaning of the above terms in the present invention based on the specific circumstances.

[0027] This utility model relates to a biomimetic circulating culture device for cultivating Dendrobium officinale using heat-resistant single-star algae, comprising: The cultivation chamber 1 is equipped with a cultivation rack 12 and multiple detachable biomimetic cultivation modules 13. The environmental control system includes a set of ultrasonic atomizing nozzles 21 for generating atomized water vapor, a liquid pipe 22 for conveying the liquid concentrate to the set of ultrasonic atomizing nozzles 21, and a circulating ventilation unit for promoting airflow within the cabin. The circulation system 3 includes a nutrient solution tank 31 for storing liquid and a return pipe 32 for recovering unabsorbed liquid back to the nutrient solution tank 31.

[0028] like Figure 1 As shown, the cultivation chamber 1 of this device consists of a transparent chamber, an internal cultivation rack 12, and multiple biomimetic cultivation modules 13 suspended thereon. The transparent chamber can be made of acrylic or glass for easy observation.

[0029] Furthermore, the biomimetic cultivation module 13 includes a hollow cultivation basket 131 and a water collection trough 132 threadedly connected to the bottom of the cultivation basket 131. The bottom of the water collection trough 132 is provided with a return hole that communicates with the return pipe 32.

[0030] Furthermore, the circulating ventilation unit includes a fan disposed on one side wall of the culture chamber 1 and a convection louver 232 disposed on the opposite side wall, which is used to form a low-speed fan (231) in the culture chamber 1 to form a horizontal circulating airflow.

[0031] Furthermore, the environmental control system also includes an LED supplementary lighting unit 24 with adjustable spectrum and light intensity, which is installed on the top of the culture chamber 1.

[0032] Furthermore, it also includes an intelligent control system, which includes a controller, a humidity sensor for monitoring the humidity of the air inside the cabin, and a timer.

[0033] Furthermore, the controller is configured to receive the signal from the humidity sensor and control the ultrasonic atomizing nozzle 21 to perform intermittent start-stop operation.

[0034] Furthermore, the controller is also configured to activate the circulating ventilation unit during the interval when the ultrasonic atomizing nozzle 21 stops operating.

[0035] Furthermore, the liquid pipe 22 is arranged along the cultivation rack 12, and a plurality of ultrasonic atomizing nozzles 21 are provided thereon, with the spray direction of the nozzles facing the cultivation basket 131 area of ​​the biomimetic cultivation module 13.

[0036] Furthermore, the body of the culture chamber 1 is made of transparent material.

[0037] Furthermore, the cultivation basket 131 is made of mesh or perforated plate material.

[0038] like Figure 2As shown, the biomimetic cultivation module 13 includes a porous or mesh-like perforated cultivation basket 131 filled with a breathable substrate such as bark and gravel. The cultivation basket 131 is secured to a water collection trough 132 with an opening at the bottom. The securing design uses a rotating buckle, similar to the connection of a bottle cap. The bottom of the water collection trough 132 has a return hole, which collects water and drains excess liquid in time through the opening at the bottom, ensuring that the substrate inside the cultivation basket is moist but not waterlogged. This perfectly simulates the growth habit of Dendrobium officinale in its native environment, where it grows epiphytically on tree trunks and rocks and "likes moisture but also needs breathability".

[0039] In the environmental control system, the ultrasonic atomizing nozzle 21 is placed in the nutrient solution tank 31 outside the chamber. In the working chamber, the water vapor generated by atomization is guided through a hose to a liquid pipe 22 arranged along the cultivation rack 12. This pipe is equipped with multiple micro nozzles, which spray water and fertilizer evenly onto the plant roots and the surrounding air in the form of extremely fine droplets.

[0040] The recirculation ventilation unit includes a low-speed fan 231 and convection louvers 232, forming a gentle and continuous horizontal airflow.

[0041] The supplemental lighting unit 24 is located inside the cabin and uses a full-spectrum LED light panel to provide the light required for photosynthesis.

[0042] The circulation system 3 collects the leachate from each water collection tank 132 through the return pipe 32 and guides it back to the bottom nutrient solution tank 31 to achieve resource recycling.

[0043] The core of the intelligent control system is a microcontroller, which receives data from temperature and humidity sensors inside the cabin and controls the atomizer to work (such as pausing for 10 minutes after every 2 minutes of operation), the fan to start intermittently (blowing for 5 minutes after atomization stops), and the supplementary lighting to switch on and off according to a preset program, so that the whole process is automated.

[0044] The significance of dual collection is that droplets dripping from the cultivation basket (131) will first fall onto the lower cultivation module, cultivation rack, or bottom plate. These droplets will splash, flow, and evaporate in all directions instead of flowing neatly towards the bulkhead, so designing only for bilge collection would make them difficult to collect.

[0045] Nutrient solution (31) is stored in the nutrient solution of a new species of heat-resistant Algae. British scientists first discovered astaxanthin from Haematococcus pluvialis, which was published in Nature. Astaxanthin is the most powerful free radical scavenger discovered so far, and the discovery of free radicals won the Nobel Prize. Science has reported on astaxanthin in detail many times, especially on its role in promoting the health of human cells. Nature series publications such as Nature Communications have reported on the important role of Haematococcus pluvialis astaxanthin in the rehabilitation of diabetes. Through cooperation with the Chinese Academy of Sciences, Zhejiang University, Sun Yat-sen University, Shenzhen University and other institutions, the nutrient solution of the new species of heat-resistant Algae was sprayed on Dendrobium officinale for the first time in China, which promoted the production and income of Dendrobium officinale. The product quality is excellent and the technology is obvious.
