Description

Technical Field

[0001] This invention relates to the field of medicinal plant seedling technology, specifically a factory-scale seedling production method for shortening the growth period of Pinellia ternata. Background Technology

[0002] Pinellia ternata ( Pinellia ternata (Thunb.) Ten. ex Breitenb. Pinellia ternata is a perennial herbaceous plant belonging to the genus Pinellia of the family Araceae. In the wild, it is often found in shady and damp grassy areas or under forests on hillsides and streamsides. It has poor ability to survive alone and has obvious weed characteristics, often growing alongside other shade-loving and damp plant groups.

[0003] Pinellia ternata is a commonly used Chinese medicinal herb. Its tuber can be used medicinally. It is poisonous and can dry dampness and resolve phlegm, relieve nausea and vomiting. When used raw, it can eliminate boils and swellings. It is mainly used to treat cough with excessive phlegm, nausea and vomiting. Externally, it is used to treat acute mastitis and acute and chronic suppurative otitis media.

[0004] Currently, existing Pinellia ternata seedling cultivation techniques mostly use non-renewable peat moss as the substrate, rely on experience for water and fertilizer management, and lack precise control methods. They generally suffer from long seedling cycles, fixed sowing times, difficulty in controlling sowing density, susceptibility to natural environmental constraints, low space utilization, and extensive management. Furthermore, traditional planar seedling cultivation requires a large area, making it difficult to meet the needs of large-scale production. Therefore, there is an urgent need to develop a Pinellia ternata seedling cultivation method that shortens the growth cycle, saves resources, and can be applied in industrial settings. Summary of the Invention

[0005] The purpose of this invention is to overcome the shortcomings of the prior art and propose a factory-scale seedling cultivation method that shortens the growth period of Pinellia ternata, which can significantly shorten the seedling cultivation cycle, improve the survival rate, and reduce the seedling cost.

[0006] To achieve the above objectives, the technical solution specifically adopted by the present invention is as follows: A factory-scale seedling cultivation method for shortening the growth period of Pinellia ternata is proposed. This method achieves three-dimensional, precise, and efficient Pinellia ternata seedling cultivation by innovatively designing a multi-layer seedling rack integrating a sensor network, a tidal irrigation system, vermiculite and perlite substrate recycling technology, and a digital management platform. The specific steps include: S1. Select the cultivation environment; S2. Erect a cultivation rack, with LED light sources and a tidal irrigation system between layers. Each layer is equipped with seedling trays, temperature and humidity sensors, light sensors and CO2 concentration sensors. Data from each sensor is uploaded to the environmental control integrated control system in real time. S3. Using vermiculite and perlite as seedling substrate, evenly sow the Pinellia ternata seeds that have been disinfected by gamma rays and treated for germination in the seedling tray, and cover them with a 3cm thick layer of seedling substrate. S4. A special nutrient solution for Pinellia ternata is supplied at regular intervals through a tidal irrigation system, and data from various sensors is analyzed using a digital management platform to dynamically adjust cultivation environment parameters and water and fertilizer supply. The digital management platform optimizes the growth model based on machine learning algorithms, enabling remote monitoring and automatic alarm functions.

[0007] Furthermore, in step S2, a 15-layer stainless steel seedling rack is used, with 9 8W LED plant grow light strips installed on each layer of the seedling rack, and the red-to-blue ratio is 4:1.

[0008] Furthermore, the environmental control system integrates a central control unit for temperature and humidity control, a micro-sprinkler irrigation control system, a ventilation system, a light intensity control system, and a fire prevention system.

[0009] Furthermore, in step S3, the mass ratio of vermiculite to perlite is 2:1, and the material is sterilized at 120°C for 30 minutes. Humic acid is added to adjust the pH to 7.0 before recycling.

[0010] Furthermore, in step S3, the seed quantity is controlled at 15–35 g / m³. 2 The sowing time is as follows: the first crop is sown in early January each year, and the seedlings are transplanted at the end of April. The second crop is sown in early May each year, and the third crop is sown in early September each year, achieving three crops of cultivation within one year.

[0011] Furthermore, the cultivation environment parameters include: air temperature 18–25℃, air humidity 40–60%, and light intensity 1000–10000 lux.

[0012] Furthermore, in step S4, the Pinellia ternata-specific nutrient solution is sprayed 2-7 times per month at a rate of 6 L / m². 2 The formula for each dose is as follows: potassium dihydrogen phosphate 40-80 mg / L, magnesium sulfate 100-300 mg / L, calcium nitrate 350-500 mg / L, ferrous sulfate 2-8 mg / L, EDTA 5-10 mg / L, boric acid 0.03-0.2 mg / L, manganese sulfate 0.01-0.2 mg / L, potassium iodide 0.0002-0.002 mg / L, zinc sulfate 0.003-0.005 mg / L, copper sulfate 0.00001-0.0003 mg / L, and ammonium molybdate 0.0001-0.001 mg / L.

[0013] Furthermore, in step S4, the Pinellia ternata seedlings are watered 2 to 4 times a week for 0.5 to 3 hours each time. During the growing season, the indoor temperature is controlled at 15 to 30°C, and ventilation is maintained.

[0014] Compared with existing technologies, this invention has the following characteristics and beneficial effects: the seedling cycle is shortened to 4 months, reducing the time by 60% compared with traditional methods; substrate costs are reduced by 60%, and space utilization is increased by 80%; digital management reduces manual intervention by 90%, and the seedling survival rate is ≥85%. This greatly improves the sustainability and economic benefits of Pinellia ternata cultivation and provides important technical support for the large-scale and standardized cultivation of Pinellia ternata.
