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 Codonopsis pilosula. Background Technology

[0002] Codonopsis pilosula ( Codonopsis pilosula (Franch.) Nannf. Codonopsis pilosula, belonging to the genus Codonopsis in the family Campanulaceae, is a perennial herbaceous vine. It has extremely high medicinal value and is known as the "King of Qi Tonification." In Traditional Chinese Medicine (TCM), Codonopsis pilosula is believed to tonify the middle energizer, replenish qi, promote body fluid production and nourish blood, strengthen the spleen and lungs, and can be used to treat symptoms such as spleen and stomach weakness, qi and blood deficiency, fatigue, loss of appetite and thirst, and chronic diarrhea with rectal prolapse. Furthermore, Codonopsis pilosula can enhance immunity, combat fatigue, and delay aging, and has a good conditioning effect on the common sub-health conditions in modern people.

[0003] Currently, existing Codonopsis pilosula 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. These techniques generally suffer from long seedling cycles, fixed sowing times, difficulty in controlling sowing density, and are constrained by the natural environment, resulting in 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 Codonopsis pilosula seedling cultivation method that shortens the growth cycle, saves resources, and can be applied in industrial settings. Summary of the Invention

[0004] This invention proposes a factory-scale seedling cultivation method to shorten the growth period of Codonopsis pilosula, which significantly shortens the seedling cultivation cycle, improves the survival rate, reduces the seedling cost, and solves the problems of long growth period, numerous pests and diseases, and high cost of artificial cultivation of Codonopsis pilosula in natural environment.

[0005] To achieve the above objectives, the technical solution specifically adopted by the present invention is as follows: A method for factory-scale seedling cultivation that shortens the growth period of Codonopsis pilosula includes the following steps: S1. Select the cultivation environment; S2. Based on the factory area, a cultivation rack is set up. Each layer of the cultivation rack is equipped with an LED light source, a tidal irrigation system, a seedling tray, a temperature and humidity sensor, a light sensor, and a CO2 concentration sensor. The data from each sensor is uploaded to the central control system in real time. The central control system includes a 24-hour controllable temperature and humidity system, a micro-sprinkler irrigation control system, a ventilation system, a light intensity control system, and a fire prevention system.

[0006] S3. Using vermiculite and perlite (mass ratio 2:1) as the seedling substrate, evenly sow the Codonopsis pilosula seeds, which have been sterilized by gamma rays and undergone germination treatment, in the seedling trays, controlling the seed quantity at 20-40 g / m². 2 Then cover the seed surface with a 3cm thick seedling substrate; S4. A special nutrient solution for Codonopsis pilosula 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 and enables remote monitoring and automatic alarm functions.

[0007] Furthermore, in step S2, a 15-layer stainless steel seedling rack is used to build the cultivation rack, which increases the seedling capacity per unit area by 15 times. Each layer of the seedling rack is equipped with 9 8W LED plant supplement light strips with a red-to-blue ratio of 4:1.

[0008] 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 6.9 before recycling.

[0009] Furthermore, in step S3, the sowing time is as follows: the first crop is cultivated in early March each year, and the second crop is cultivated in early September each year, achieving two crops of cultivation within one year.

[0010] Furthermore, the cultivation environment parameters include: air temperature 18–25℃, air humidity 40–60%, and light intensity 1000–10000 lux.

[0011] Furthermore, in step S4, the Codonopsis pilosula-specific nutrient solution is sprayed 2-7 times per month at a rate of 6 L / m³. 2 The formula for the Codonopsis pilosula-specific nutrient solution is as follows: potassium dihydrogen phosphate 10-100 mg / L, magnesium sulfate 100-350 mg / L, calcium sulfate 200-700 mg / L, ferrous sulfate 2-10 mg / L, EDTA 5-15 mg / L, boric acid 0.001-0.05 mg / L, manganese sulfate 0.01-0.1 mg / L, potassium nitrate 100-500 mg / L, zinc sulfate 0.01-0.1 mg / L, copper sulfate 0.00001-0.0002 mg / L, ammonium molybdate 0.0002-0.001 mg / L, ammonium nitrate 10-100 mg / L, potassium iodide 0.001-0.01 mg / L, and cobalt chloride 0.00002-0.001 mg / L.

[0012] Furthermore, in step S4, the Codonopsis pilosula 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.

[0013] Compared with existing technologies, this invention has the following characteristics and beneficial effects: the seedling cycle is shortened to 6 months, reducing the time by 50% 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 Codonopsis pilosula cultivation, and provides important technical support for the large-scale and standardized cultivation of Codonopsis pilosula.
