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.

Strawberry cultivation in the south has a brilliant approach
In recent years, during strawberry cultivation experiments and production processes, the author has developed a comprehensive set of highly effective techniques tailored to meet the "early maturation, high yield, high quality, cost reduction, labor saving, and value enhancement" needs in southern regions. These methods have been carefully refined through extensive field trials and practical application.
I. Laying a Solid Foundation for Early Ripening and High Yield
1. Selecting early-maturing varieties is crucial for achieving both early harvest and strong market competitiveness. Varieties such as Fengxiang, Saga Suixiang, Gu Nugan, Zhang Ji, Tudela, Xingxiang, and Bengwengv have shown excellent adaptability to the climate of Guangdong and Guangxi, with high yield and superior fruit quality. These varieties also exhibit early flower bud differentiation, early flowering, and early fruit ripening, along with good disease resistance.
2. Using high-quality seedlings is essential for ensuring strong plant establishment. Healthy seedlings should be short and sturdy, with no pests, a fresh weight over 25 grams, a stem diameter of at least 0.8 cm, well-developed roots, 4–5 leaves, large green foliage, and full central buds. Virus-free seedlings produced through tissue culture can significantly improve yield by 15% to 30%.
3. Timely planting is key to maximizing growth potential. In Guangxi, the ideal planting window is from late September to mid-October when the average daily temperature is around 25–26°C. Planting should be done as early as possible, using a double-row triangular layout with spacing of 18–20 cm between plants, 30 cm between rows, and 7,400–8,200 plants per acre. This ensures robust plant development and earlier fruiting.
II. Strict Planting Techniques to Minimize Seedling Mortality
Proper planting depth is critical—seedlings should be planted just above ground level to avoid root exposure or deep burial. Shallow planting achieves a survival rate of nearly 99.5%. After planting, it’s important to water immediately and cover with shade nets, especially on sunny days. For long-distance or overnight seedlings, applying yellow mud to the roots before planting improves survival. Watering should be done daily for the first seven days, then reduced as the seedlings establish.
III. Efficient Fertilization and Labor Management
Applying basal fertilizer properly ensures consistent nutrient supply throughout the growing season, promoting healthy growth, flowering, and fruiting while reducing the need for frequent top-dressing. However, excessive fertilizer applied all at once can cause damage. The author implemented a layered fertilization method, including “sandwich†and “shallow ditch†techniques.
The “sandwich†method involves placing fertilizer in the middle layer of the bed, avoiding direct contact with seedlings and minimizing burn risk. It results in a survival rate of up to 99.5%. The “shallow ditch†method applies fertilizer in shallow trenches after two to three weeks, improving efficiency and ease of application.
IV. Mulching to Reduce Soil Management Efforts
Mulching with black or silver-black film helps retain soil moisture, suppress weeds, and reduce manual labor. In Nanning, Guangxi, mulching is best done in mid-to-late November. Too early or too late can harm root growth or reduce effectiveness. Black films are preferred over transparent ones for better weed control and temperature regulation.
V. Integrated Pest and Disease Control to Lower Costs
Common diseases include leaf spot, powdery mildew, gray mold, and root rot, while pests like spider mites, thrips, and aphids are prevalent. Prevention starts with crop rotation, resistant varieties, clean compost, proper planting density, and timely removal of diseased parts. Early detection and use of low-toxicity, high-efficiency pesticides help keep costs down and maintain plant health.
VI. Optimizing Flower and Fruit Management for Better Quality
Managing flowers and fruits effectively enhances fruit size, color, and quality. Removing weak or malformed flowers and fruits reduces defects and increases single fruit weight. Typically, 12–15 fruits per plant are recommended for optimal results.
VII. Proper Harvesting and Post-Harvest Handling to Enhance Value
Harvesting at the right maturity stage is essential to maintain quality and extend shelf life. Strawberries are usually harvested at 85–90% maturity, but during hot periods (March–May), harvesting at 70–80% maturity is advisable. Gentle picking and careful handling prevent damage. After harvesting, grading and packaging in transparent containers help increase market value and ensure uniform quality for transport.
