DETAILED DESCRIPTION

[0026] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only some of the embodiments of the present application, not all.

[0027] Reference Figures 1 to 7 A traditional Chinese medicine planting and seedling raising device includes an upper planting frame 1 and a lower processing frame 2, and the upper planting frame 1 is fixedly installed on the top of the lower processing frame 2. A plurality of moving wheels 3 are fixedly installed on the bottom of the lower processing frame 2, and the position of the device can be flexibly adjusted according to the layout of a seedling raising site, which helps to reduce the labor intensity of manual carrying. An electrical cabinet 4 and a water storage tank 6 are fixedly installed in the lower processing frame 2. The electrical cabinet 4 is used to realize automatic management of the seedling raising process (this is prior art, and details are not described herein again). The outer wall of the water storage tank 6 is fixedly connected with a nutrient device 5. The nutrient device 5 can accurately prepare corresponding nutrient solution (such as the proportion of nitrogen, phosphorus, potassium and trace elements) according to the growth requirements of different traditional Chinese medicine varieties, so as to meet the nutrient requirements of different medicinal materials in the seedling raising period (this is prior art, and details are not described herein again). The nutrient device 5 reduces the error and workload of manual preparation, improves the seedling raising efficiency and consistency, and the outer wall of the water storage tank 6 is fixedly connected with a water guide pipe 18. The water guide pipe 18 is connected with a valve control mechanism (not shown in the figure, which is prior art). The valve control mechanism controls the water guide pipe 18 to realize the switching of the water inlet and drainage functions, so that the water guide pipe 18 can not only supplement clean water into the water storage tank 6, cooperate with the nutrient device 5 to prepare new nutrient solution, or dilute and adjust the nutrient solution when the concentration of the nutrient solution is too high, but also quickly discharge the waste liquid in the water storage tank 6 when the nutrient solution is invalid, thereby reducing the workload of manual pouring. The inner wall of the water storage tank 6 is fixedly installed with a sensor 16. The sensor 16 monitors the composition (such as the concentration of nitrogen, phosphorus and potassium, pH value, etc.) and state of the nutrient solution in real time, judges whether the nutrient solution can still meet the growth requirements of seedlings, and if the composition still meets the standard, the nutrient solution can be continuously used by only supplementing the missing nutrients. If the composition is unbalanced or contaminated (such as the breeding of bacteria), the nutrient solution is discharged through the water guide pipe 18 and replaced with new solution, so as to avoid resource waste caused by blind replacement or affect the seedling raising effect due to long-term non-replacement.

The capillary column 25 on the first capillary plate 23 is pulled down, and the herbaceous medicinal materials (such as peppermint, andrographis, and perilla) with strong oxygen preference and root system resistance to erosion are planted in the planting basket 21 above the first capillary plate 23, so that the top of the capillary column 25 on the first capillary plate 23 does not contact the bottom of the planting basket 21, and the capillary column 25 on the second capillary plate 24 is pushed up, and the root and rhizome medicinal materials (such as American ginseng, angelica, and atractylodes) with fleshy roots and fear of flooding are planted in the planting basket 21 above the second capillary plate 24, so that the top of the capillary column 25 on the second capillary plate 24 is close to the bottom of the planting basket 21 above it. For the herbaceous medicinal materials with strong oxygen preference and root system resistance to erosion, the capillary column 25 on the first capillary plate 23 is pulled down to form sufficient space, so that the capillary column 25 is in full contact with the flowing nutrient solution, creating an excellent growth environment for the herbaceous plants, ensuring that the root system has enough space to contact the air, and the nutrient solution is accurately delivered to the plant root through the capillary effect of the first capillary plate 23, meeting the oxygen and nutrient requirements of the plants.For the root, the root of the rhizome medicine, push the capillary column 25 on the second capillary plate 24, make it close to the bottom of the planting basket 21, let the root system of the rhizome medicine contact with the capillary column 25, strengthen the stability of the root, at the same time, through the capillary effect, high efficiency supplement nutrients, effectively reduce the risk of root rot, the capillary column 25 on the first capillary plate 23 can form the karman vortex street effect in the flowing nutrient solution, help to enhance the turbulence degree of the nutrient solution, greatly improve the oxygen dissolution efficiency in the nutrient solution, equivalent to increase the“oxygen agitator”in the nutrient solution, make the nutrient solution can better provide sufficient oxygen for the plant root system, help to reduce the plant root rot phenomenon, provide a good oxygen environment for the plant growth, arrange different traditional Chinese medicine varieties at intervals, effectively avoid the mutual entanglement and competition in the process of root growth, divide the growth territory for different medicines, let them grow healthily without interference, be beneficial to fully utilize the planting space, improve the planting density, at the same time, ensure that each medicine can obtain enough growth resources, promote the healthy growth of each medicine, improve the overall planting benefit.

The valve pipe 14 is used for controlling and distributing water flow to each group of planting assemblies. The inner wall of the upper planting frame 1 is fixedly installed with a backwater pipe 9. The water outlet of the backwater pipe 9 extends into the water storage tank 6. A plurality of water inlets of the backwater pipe 9 are fixedly communicated with a plurality of water collecting pipes 10 respectively. The plurality of water collecting pipes 10 correspond to a plurality of groups of planting assemblies respectively. The side wall of the water collecting pipe 10 is fixedly communicated with a plurality of water outlet pipes 11. The plurality of water outlet pipes 11 correspond to a plurality of fixed frames 20 respectively and are fixedly communicated with water outlets of the corresponding fixed frames 20. The fixed frame 20 is arranged obliquely, and the water inlet 26 is higher than the water outlet. The inner wall of the fixed frame 20 is fixedly installed with a stepped water falling block 27. The water falling block 27 and the water inlet 26 are located at the same end of the fixed frame 20, and the water falling block 27 is located below the water inlet 26. After the water pump 17 is started, the nutrient solution is uniformly delivered to the water inlet 26 through the filtering device 12, the valve pipe 14, the distribution pipe 13 and the water inlet pipe 15, and flows back to the water storage tank 6 through the water outlet pipe 11, the water collecting pipe 10 and the backwater pipe 9, forming a stable circulation path. The filtering device 12 filters the nutrient solution, can intercept silt, microbial debris or other suspended matters in the water, avoids pipe blockage or affects seedling root absorption, at the same time, filtering can reduce the interference of impurities on the detection accuracy of the sensor 16, ensures data accuracy, removes part of metabolic waste or pollutants through filtering, can delay the deterioration speed of the nutrient solution, prolongs the use cycle thereof, when the nutrient solution impacts the stepped water falling block 27 from the water inlet 26, the water flow cuts air and produces splashing in the falling process, forms a large amount of fine water droplets in contact with air, significantly increases the dissolved oxygen content, without additional aeration equipment, efficiently improves the oxygen content of the nutrient solution through physical action, provides sufficient oxygen for the root system of the oxygen-loving medicinal material, reduces the risk of root rot caused by oxygen deficiency, the inclined state of the fixed frame 20 makes the nutrient solution flow in from the high end and flow out from the low end, utilizes gravity to accelerate the water flow speed, at the same time, the water flow forms natural turbulent flow on the inclined surface, further destroys the laminar flow state of the liquid surface, increases the oxygen dissolving surface area, maintains the dissolved oxygen content in the nutrient solution at a high level, is especially suitable for oxygen demand sensitive fleshy roots and waterlogging-averse medicinal materials, effectively prevents root system from rotting due to oxygen deficiency, improves the survival rate of medicinal materials, and the upper part of each planting assembly is provided with a light supplementing assembly. The light supplementing assembly comprises a plurality of light supplementing lamps 8. The light supplementing lamps 8 are fixedly connected with the inner wall of the upper planting frame 1 through mounting rods 7. Starting the light supplementing lamps 8 provides sufficient and suitable light for the water-cultivated Chinese medicinal seedlings. Customized light can be provided according to the light demand (such as shade and sun characteristics) of different Chinese medicinal varieties.Make up the problem of insufficient natural light, ensure the photosynthesis efficiency of medicinal materials, promote the synthesis of chlorophyll and the accumulation of organic matter, and provide stable light energy support for the growth of medicinal materials.

[0030] In use, the lower processing frame 2 is first opened, clean water is injected into the water storage tank 6 through the water guide pipe 18, the sensor 16 is turned on, and the nutrient solution required for water culture is precisely prepared according to the variety of traditional Chinese medicine to be cultivated by using the nutrient device 5. After the preparation of the nutrient solution is completed, the upper planting frame 1 is opened, the capillary column 25 on the first capillary plate 23 is pulled down to form a sufficient space between the capillary column 25 and the first capillary plate 23, so that the capillary column 25 on the first capillary plate 23 is in full contact with the flowing nutrient solution. Subsequently, the herbaceous medicinal materials with strong oxygen preference and root system resistant to flushing are planted in the planting basket 21 above the first capillary plate 23, thereby creating an excellent growth environment for the oxygen-loving herbaceous plants, and the nutrient solution is precisely delivered to the plant roots through the capillary effect of the first capillary plate 23; the capillary column 25 on the second capillary plate 24 is pushed up to be close to the bottom of the planting basket 21, and the root stem medicinal materials with fleshy roots and fear of waterlogging are planted in the planting basket 21 above the second capillary plate 24, so that the root system of the root stem medicinal materials can be in contact with the capillary column 25, thereby not only enhancing the stability of the roots, but also efficiently supplementing nutrients through the capillary effect, effectively reducing the risk of root rot, and the capillary column 25 on the first capillary plate 23 can form a Karman vortex street effect in the flowing nutrient solution, thereby significantly enhancing the turbulence degree of the nutrient solution and greatly improving the oxygen dissolution efficiency in the nutrient solution, which is helpful to reduce the phenomenon of plant root rot.

[0031] The light supplementing lamp 8 is started to provide sufficient light for the water-cultured traditional Chinese medicine, the water pump 17 and the filtering device 12 are turned on, the nutrient solution in the water storage tank 6 is pumped to the valve pipe 14, the nutrient solution can flow into the distribution pipe 13 uniformly through the adjustment valve, and then is delivered to the water inlet 26 through the water inlet pipe 15. After the nutrient solution flows out of the water inlet 26, it first impacts the stepped water falling block 27 in the fixed frame 20. The water flow cuts the air and produces sputtering in the falling process, which significantly increases the oxygen dissolution amount of the nutrient solution. The fixed frame 20 is in an inclined state, the nutrient solution flows in from the high end of the fixed frame 20 and flows out from the low end, and the flow is driven by the gravity of the water flow itself, without the need for additional power assistance. Not only does this make the nutrient solution naturally form a turbulent flow in the inclined tank, further promoting oxygen dissolution and effectively preventing root hypoxia, but it also avoids the formation of dead water areas in some areas, reducing the probability of plant root rot. The nutrient solution flowing through the planting basket 21 is collected into the water collecting pipe 10 through the water outlet pipe 11, and finally returns to the water storage tank 6 through the backwater pipe 9. The sensor 16 monitors the nutrient solution composition in real time. If it can still be used, it continues to be recycled after supplementing nutrients. The filtering device 12 pretreats the nutrient solution. When the nutrient solution reaches the use limit, it is discharged through the water guide pipe 18 and new water is injected.

[0032] The above merely describes preferred specific embodiments of the present application, but the protection scope of the present application is not limited thereto, and any person skilled in the art, according to the technical solution and inventive concept of the present application, makes equivalent replacement or change within the technical range disclosed by the present application, which should be covered within the protection scope of the present application.
