After the harvest of red peony, the majority are stored in cellars and sold gradually over time. However, improper storage conditions can sometimes lead to rotten cellars, which cause significant losses. To prevent this issue, the following measures are recommended:
Before storage—about 10 to 15 days after harvest—it is essential to take preventive steps. Red peonies have high moisture content right after harvest, making them vulnerable to bacterial infections from the field. This can result in diseases that lead to rot during storage. Therefore, it's crucial to implement disease control before placing the peonies in the cellar. At this stage, select disease-free and insect-free roots and treat them with either 40% carbendazim wettable powder diluted 800 times or thiophanate-methyl wettable powder at 1000 times. Soaking the roots thoroughly is important, then allowing excess water to drain and drying them before they are placed into the cellar.
During the initial storage period—approximately 30 days after the peonies are placed in the cellar—the respiration rate of the red peonies is still high. If the temperature and humidity inside the cellar are too high, the roots may start to sprout or develop mold. To avoid this, proper ventilation, cooling, and moisture control are necessary. The ideal temperature should be kept below 15°C, preferably between 12°C and 13°C. High humidity often leads to "sweating" on the surface of the pile, which can damage the roots. Covering the pile with a layer of hay helps protect against moisture damage. The cellar’s humidity should be maintained around 85%.
In the middle of the storage period—around 30 days after being placed in the cellar until early spring—the temperature drops, increasing the risk of cold damage. At this point, maintaining warmth and moisture is key. The cellar temperature should be controlled between 12°C and 14°C, not falling below 10°C. Relative humidity needs to stay between 90% and 95%. Stacking grass around and on top of the pile helps improve insulation and retain heat.
During the late storage period—just before spring arrives—the temperature begins to rise, but cold air pockets can still occur. At this stage, the red peonies have weaker respiration and lower resistance to environmental stress. It is important to keep the cellar temperature stable and ensure good ventilation. Monitor weather changes closely and maintain a temperature of around 12°C. The relative humidity should not drop below 80%. If signs of rot appear, do not remove the entire batch immediately. Instead, handle the affected areas as soon as possible. Any rotting parts on the surface should be removed promptly to prevent further spread.
Mini Locking Plate
The mini locking system can be used for the fixation of ossicles and small bone fragments, osteotomy, arthrodesis, and replantation and reconstruction of ossicles and small bone fragments.
It is composed of micro locking plate 1.5mm/2.0mm/2.4mm/2.7mm series, covering a variety of plate types and a wide range of indications. The plates are all anatomical design, which reduces the need for shaping and helps to reduce the workload of surgeons. Low profile and countersunk screw design can reduce soft tissue injury. Matching orthopedic screws self-tapping design, convenient implantation, screw plum design, reduce screw hexagonal sliding teeth. The composite hole design can not only realize the compression of the fracture end, but also can be used as a locking internal orthopedic fixation frame. Part of the reconstruction structure is convenient for the surgeon to tailor the implant according to the actual situation in the reoperation, and increase the flexibility of the operation. Its indications are mainly phalanx, metacarpal, scaphoid and other carpal bones, ulnar styloid process and capitulum, radial head and styloid process fracture fixation. The 1.5mm orthopedic implants titanium system is mainly used for the middle and proximal phalanx, the 2.0mm orthopedic plates system for the metacarpal bones, the 2.4mm implant locking plate system for the first metacarpal bones and carpal bones, and the 2.7mm mini plate system is mainly used for the distal ulna and radius. According to the clinical research, the micro-locking plate internal fixation in the treatment of multiple comminuted metacarpal fractures can effectively achieve the anatomical reduction and healing required by the clinic. The patients have good postoperative healing, and the functional recovery of the affected limb is good during the postoperative follow-up. It has good clinical effect and can be further promoted and applied.
