Description

Technical Field

[0001] This utility model relates to the field of Yunnan Polygonatum cultivation technology, specifically a hydroponic device for Yunnan Polygonatum breeding. Background Technology

[0002] As a traditional and precious Chinese medicinal herb, Polygonatum yunnanense has been widely used in the fields of medicine and health care, and market demand continues to rise. With the expansion of artificial cultivation, the demand for breeding high-quality varieties of Polygonatum yunnanense is becoming increasingly urgent. Efficient and precise breeding technology is the key support for cultivating superior varieties. Among them, hydroponics technology has become an important breeding method in Polygonatum yunnanense because it can precisely control growth conditions such as water, nutrients, and temperature, and avoid soil continuous cropping obstacles and pest infestation.

[0003] However, existing hydroponic devices for *Polygonatum yunnanense* breeding have many limitations in practical applications. For example, traditional hydroponic devices mostly use centralized water supply systems, meaning multiple culture units share the same water supply equipment. This makes it impossible to differentiate the management of *Polygonatum yunnanense* breeding materials from different batches and with different genotypes. *Polygonatum yunnanense* breeding materials exhibit significant diversity; different genotypes naturally differ in growth habits and nutrient requirements. Furthermore, the same material has drastically different requirements for water and nutrient solution at different growth stages, such as germination, seedling, and mature stages. For instance, some genotypes of *Polygonatum yunnanense* have fragile root systems in the seedling stage and require lower water levels to prevent root rot, while other genotypes require sufficient water in the mature stage to promote tuber enlargement. If a unified water supply is used, some materials may experience "overwatering," leading to root hypoxia and rot, while others may experience "insufficient watering," resulting in slow growth. This severely affects the survival rate and growth quality of the breeding materials, reducing the accuracy of breeding selection.

[0004] To address these issues, we have provided a hydroponic device for breeding Polygonatum yunnanense. Utility Model Content

The side end of the spring 402 is connected to the fixed plate 404. The spring 402 is used to increase the thrust of the fixed arc 401, so that the fixed arc 401 has the force to hold the Solomon's seal seedling. The support rod 403 is slidably connected inside the fixed plate 404. The support rod 403 is used to support the fixed arc 401 and prevent it from tilting. The operating lever 405 is connected to the tail end of the support rod 403. The operating lever 405 can easily pull the support rod 403 and can easily control the fixed arc 401.

[0040] The culture plate 3 has a water inlet 5 at the top, and the upper end of the water inlet 5 is connected to the positioning frame 6. A water supply pipe 7 is provided on one side of the culture rack 1, and a gate 8 is provided on the other side. A sealing strip is provided on the outer ring of the gate 8. The gate 8 is located at the end of the water storage channel 2 and is used to block the side end of the water storage channel 2. Multiple water supply heads 9 are connected to the side end of the water supply pipe 7. The water supply heads 9 are connected to the water inlet 5. The positioning frame 6 is used to facilitate the connection between the water supply heads 9 and the water inlet 5. A valve 10 is provided inside the water supply head 9. The valve 10 is used to control the opening and closing of the water supply head 9.

[0041] A pump 11 is connected to the side of the water supply pipe 7. A mixing tank 12 is installed on the side of the pump 11. The water inlet of the pump 11 is connected to the mixing tank 12 through a water pipe. The pump 11 can supply water for hydroponics to the water supply pipe 7. A water inlet pipe is connected to the side of the mixing tank 12, and a liquid inlet is connected to the top.

Specifically, the roots of the *Polygonatum yunnanense* seedlings are passed through the planting hole, so that the diameter of the stem is located between the two fixing arcs 401. The spring 402 provides thrust to the fixing arcs 401, thereby clamping the *Polygonatum yunnanense* seedlings between the two fixing arcs 401 to prevent them from tipping over; then, the cultivation plate 3 is slidably placed on the upper end of the water storage channel 2, so that its side end contacts the sealing plate 17. At this time, the water delivery head 9 is just located within the positioning frame 6. The water delivery head 9 is connected to the water inlet 5. Then, the telescopic rod 13 presses down the gate plate 8, so that the gate... Plate 8 blocks the water storage channel 2; pump 11 is started to draw the cultivation water from the mixing tank 12, and the cultivation water enters the water supply pipe 7. The opening and closing of the water supply head 9 is controlled by valve 10 to inject the cultivation water into the water storage channel 2 for hydroponic cultivation of the Yunnan Polygonatum seedlings; when it is necessary to replace the cultivation water in the water storage channel 2, simply raise the gate plate 8 by telescopic rod 13, so that the cultivation water will flow into the drainage ditch 14 and then be discharged from the device, and then replenished by water supply head 9; when it is necessary to remove the Yunnan Polygonatum seedlings, use telescopic rod 13 to fully raise the gate plate 8, and then slide the cultivation plate 3 out through the groove 16 of the water storage channel 2 to remove it, so that the cultivation plate 3 can be removed from the top of the cultivation rack 1.
