Manual watering requires frequent operation, which is time-consuming and labor-intensive. Uneven water control can easily lead to seedlings suffering from water shortage or waterlogging. When placed directly on the ground, the bottom of the flowerpot is prone to water accumulation and root rot due to damp ground. Furthermore, the discharged water is not recycled, resulting in water waste. Utility Model Content

[0020] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0021] In modern agricultural development, vegetable seedling cultivation, as the starting point of the planting process, directly impacts the yield and quality of subsequent production. Traditional seedling cultivation methods, due to insufficient flexibility and significant resource waste, are no longer sufficient to meet the demands of large-scale, precision modern agricultural production. The emergence of modular vegetable seedling trays offers an innovative solution to these problems by breaking down the seedling system into standardized modules that operate independently yet collaboratively. This design, incorporating industrial modular thinking, scientifically separates environmental control, nutrient supply, and seedling management, giving the seedling trays combinable, easily replaceable, and expandable characteristics, effectively improving the adaptability and efficiency of seedling operations.

[0022] Tracing its development, early seedling cultivation relied on single-function plastic trays or seedling pots. These containers not only failed to precisely control environmental parameters but also suffered from drawbacks such as extensive water and fertilizer management and poor variety compatibility. With the advancement of agricultural technology, after 2010, seedling trays began to evolve towards basic functional modularization, with designs combining them with pluggable irrigation modules. From 2016 onwards, temperature control and LED lighting modules were integrated through magnetic or slotted designs, such as the "intelligent temperature-controlled seedling tray system," which can adjust local temperatures as needed. From 2021 to the present, intelligent integrated modules that combine sensors and IoT technology have become mainstream. For example, the "AI intelligent seedling module combination" can monitor substrate moisture in real time and automatically trigger irrigation, driving the development of seedling cultivation towards intelligence.

[0023] From a core design perspective, the modular vegetable seedling tray is composed of multiple functional modules working together. The seedling unit module, as the basic carrier, adopts a standardized tray design, with customized hole depth and spacing based on crop characteristics. For example, shallow holes are suitable for leafy vegetables, while deeper holes are suitable for root vegetables. The material is food-grade PP plastic with added antibacterial agents, and the bottom ventilation holes and drainage channels balance oxygen supply and flood prevention needs. The intelligent irrigation module includes drip irrigation, tidal irrigation, and a fertigation system. The drip irrigation module achieves precise water replenishment with a flow accuracy of ±5% through micro-pressure differential capillaries, saving over 30% of water. The fertigation module automatically mixes nutrient solution according to EC values, saving over 70% of fertilizer. The environmental control module integrates temperature control, light, and humidity subsystems. The temperature control module uses PTC heating elements and fans to maintain the temperature difference within ±1℃. The LED lighting module can switch the spectrum (blue light promotes root development during the seedling stage, and red-blue composite light promotes photosynthesis during the growth stage). The humidity submodule maintains the substrate humidity within the optimal range of 60%-80% through an ultrasonic atomizer. The data monitoring module transmits data such as EC / pH value, temperature and humidity in real time through LoRa technology, and supports threshold alarm function, such as automatic warning when the matrix EC value exceeds 2.5mS / cm.

[0024] In practical applications, modular design demonstrates significant advantages. In terms of production efficiency, parallel operation mode shortens the single-batch seedling cycle by 15%-20%. One farm, after adopting this design, increased seedling efficiency from 3000 seedlings / day to 4500 seedlings / day. Furthermore, by changing the seedling unit module, the switch from leafy vegetables to root crops can be completed within 48 hours. Regarding resource utilization, drip irrigation and fertigation technologies reduce water and fertilizer losses to below 10% and 8%, respectively. Temperature control and LED lighting modules save 40% more energy than traditional greenhouses. In terms of management costs, automation modules reduce labor costs per acre from 800 yuan / season to 300 yuan / season, increase seedling survival rate from 75% to 95%, and reduce loss costs per hectare by approximately 2000 yuan. In terms of flexibility, it is compatible with the cultivation of over 20 kinds of vegetable seedlings. From small farms to intelligent greenhouses of tens of thousands of square meters, it can be expanded and adapted through modules, with an equipment reuse rate exceeding 90%.

[0025] However, the technology still faces challenges in its promotion. The initial equipment cost of 12,000-20,000 yuan per set puts pressure on small and medium-sized farms; inconsistent module interface specifications from different manufacturers lead to insufficient compatibility; and the operational threshold of the IoT system deters some farmers. In response, the industry has explored solutions: government subsidies and a "quarterly rental" model (rent approximately 2,000 yuan per quarter per set) reduce procurement pressure; the interface technical specifications released by the Ministry of Agriculture and Rural Affairs in 2023 standardized module standards; and the one-click control interface of a mobile APP simplifies the operation steps to within three steps, coupled with voice prompts to reduce the difficulty of use.

[0026] Looking ahead, modular seedling trays will develop towards deeper integration with intelligence. AI prediction seedling raising technology can predict the optimal temperature and humidity curves through historical data and give early warnings of disease risks; the application of 5G and edge computing will shorten the remote control response delay from 10 seconds to within 1 second. In terms of material innovation, corn starch-based bioplastic seedling units can be degraded into the soil, and nano-TiO2 coated modules have photocatalytic antibacterial functions. In terms of function integration, the integrated seedling raising and transplanting module can increase the survival rate to 98% through degradable planting cups, and the newly added image recognition camera module can give real-time warnings of diseases and pests such as downy mildew and aphids.

[0027] As the core innovation of modern agricultural seedling raising, the modular vegetable seedling tray has broken through the traditional bottlenecks in the mode of "function splitting - standard integration - intelligent collaboration", and has significant advantages in resource conservation, cost control and flexibility. Despite the current challenges of cost and standardization, its deep integration with Internet of Things and new material technologies is driving the seedling raising towards precision, intelligence and low carbon. With the iteration of technology and the improvement of the industrial ecosystem, this system is expected to become the core infrastructure for the upgrading of facility agriculture, providing solid technical support for the stable supply of vegetables and rural revitalization.
