Description

Technical Field

[0001] This utility model relates to the field of transplanting seedlings of Polygonatum yunnanense, specifically a device for improving the survival rate of transplanted seedlings of Polygonatum yunnanense. Background Technology

[0002] "Yunnan Polygonatum seedlings" refers to seedlings of *Polygonatum yunnanense* that have undergone a period of growth and development and have reached a stage where they can be transplanted or used for other production purposes. Transplanting of *Polygonatum yunnanense* seedlings is an important step in the artificial cultivation process, and it is generally carried out in spring or autumn. Spring transplanting is best done from late March to early April, when the temperature gradually rises and the soil moisture is suitable, which is conducive to the growth of *Polygonatum yunnanense* seedlings and the recovery of their root system. Autumn transplanting is done from mid-October to early November, when the above-ground parts of *Polygonatum yunnanense* grow slowly, but the underground root system still has a certain degree of growth vitality, allowing it to adapt to the new environment more quickly after transplanting.

[0003] A search revealed Chinese Patent Publication No. CN 218550743 U, which discloses a seedling raising device for *Polygonatum yunnanense*, comprising a box and a seedling tray. The seedling tray is slidably connected to the box, and several seedling troughs are provided on the tray. A seedling pushing plate is slidably connected to the inner cavity of each seedling trough, and a seedling pushing hole is provided on the bottom surface of each trough. A support column is fixedly connected to the bottom surface of the box, and the upper end of the support column abuts against a movable plate. A seedling pushing mechanism is provided inside the box to drive the seedling tray to slide within the box. This invention, through the cooperation of the seedling pushing mechanism and the support column, can push *Polygonatum yunnanense* seedlings and substrate together out of the seedling trough during transplanting. This seedling removal method does not damage the roots and stems of the seedlings, which helps to improve the survival rate of transplanting. Furthermore, it can simultaneously remove all the *Polygonatum yunnanense* seedlings from the seedling tray, improving the efficiency of seedling removal and saving manpower.

[0004] Regarding the aforementioned technologies, the inventors have discovered the following drawbacks: In actual use, when watering transplanted seedlings of Polygonatum yunnanense, it is necessary to manually carry a watering can to water each seedling individually, which results in low watering efficiency and uneven watering, affecting the survival rate of the seedlings. Excessive water in the roots of the seedlings can cause root necrosis at the bottom, while also wasting water. Utility Model Content

[0014] (III) Beneficial Effects

[0015] This invention provides a device for improving the survival rate of transplanted *Polygonatum yunnanense* seedlings. It has the following beneficial effects:

[0016] 1. This device for improving the survival rate of transplanted *Polygonatum yunnanense* seedlings involves setting up a cultivation rack, cultivation cups, a watering pipe, and a connecting pipe. *Polygonatum yunnanense* seedlings can be planted in the cultivation cups. Water is supplied through the watering pipe, which directs the water to the cultivation rack, then flows over the bottom of the cultivation cup and into the cup through the inlet hole. The roots of the *Polygonatum yunnanense* seedlings inside the cultivation cup can penetrate a baffle, allowing them to absorb water. The water flow then passes through the connecting pipe into the next cultivation rack for further watering. This achieves a circulating water flow, conserving water resources and increasing the survival rate of *Polygonatum yunnanense* seedlings.

[0017] 2. This device for improving the survival rate of transplanted *Polygonatum yunnanense* seedlings utilizes a horizontal plate. During rain, rainwater can directly water the top layer of cultivation cups. Excess water can flow through drip holes on the horizontal plate into the cultivation rack for cyclical watering, effectively utilizing natural water resources. Simultaneously, adding an aqueous solution to the water automatically treats the roots of the *Polygonatum yunnanense* seedlings. Compared to manually dipping the seedlings in the solution, this improves work efficiency, reduces the labor burden on growers, and ensures more even root treatment, thus contributing to a higher transplant survival rate.
