Open the cultivation shell 11, place the receiving frame 13 on the inner side of the cultivation shell 11, and place the seedlings on the tray 14 to carry and cultivate the seedlings. The positioning device 19 squeezes the outer side of the receiving frame 13 to achieve the effect of squeezing and fixing the components, preventing shaking during subsequent operations, improving the stability of component operations, and avoiding affecting the subsequent operation results. When the positioning device 19 releases the squeezing of the receiving frame 13, it is convenient for replacement and installation, reducing the difficulty of component replacement. Gas is transported to the inside of the cultivation shell 11 through the low-temperature device 2 to achieve the effect of low-temperature cultivation, adapt to physiological characteristics, promote root development, enhance stress resistance, cope with extreme weather, regulate the growth cycle, meet production needs, inhibit pests and diseases, and reduce chemical intervention. Low-temperature cultivation is an important technical means for bitter melon seedling cultivation. It stimulates the seedlings' resistance to stress by simulating adverse environments, while optimizing growth rhythm and reducing production risks. This technology is especially suitable for off-season cultivation in facility agriculture, early spring marketing or large-scale seedling cultivation scenarios.

Secondly, it is easy to cause corrosion to the equipment, thereby affecting the service life of the equipment. On the one hand, water flows to the side of the drainage shell 16 and then flows outward. On the other hand, moisture is discharged through the ventilation device 3. This technology is particularly suitable for off-season cultivation, early spring listing or large-scale seedling cultivation in facility agriculture. It can achieve a win-win situation of economic and ecological benefits while ensuring the quality of seedlings. The light source for the seedlings is supplemented by the light lamp 12, simulating natural light to meet the photosynthesis needs of plants, especially in low temperature environments to supplement the problem of insufficient light, promote the seedlings to have thick stems and green leaves. During the cultivation process, water vapor is easily attached to the inside of the equipment. By opening the U-shaped groove 15, the condensed water is guided to be discharged in an orderly manner to avoid retention, and then the water is discharged through the ventilation device 12. Position 3 adjusts the humidity inside the equipment, increases the oxygen inside the equipment, and maintains the growth of seedlings, thereby reducing condensation inside the equipment, ventilating the interior of the equipment, maintaining the balance of gas components, reducing pollution and metabolite accumulation, and air flow can reduce the formation of condensed water, keep the box dry and clean, control the uniformity of temperature and humidity, avoid local overheating or overcooling, and increase the oxygen inside the equipment through air flow to avoid the accumulation of metabolic waste, lack of oxygen or pollution risks caused by poor air circulation. The second grid plate 36 plays the role of blocking impurities, preventing external impurities from entering, and preventing them from affecting the cultivation process.
