Medical sterile container is a common medical equipment, mainly used for the storage of instruments in the process of packaging, sterilization, transit, storage, etc.
The sterilization box as a whole is made of anodized aluminum, which provides anti-pressure, moisture-proof and dust-proof protection during sterilization, transportation, transit and use. The sterilization container has good sealing performance, and the sealing ring is made of silicone material:. The safety lock device is locked once to avoid misoperation.

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 the "early maturing, high yield, high quality, cost-saving, labor-saving, and value-added" requirements in southern regions. These methods have proven successful in adapting to local climate conditions and improving overall productivity.
**I. Building a Strong Foundation for Early Ripening and High Yield**
1. **Choosing Early-Maturing Varieties**: Selecting suitable early-maturing varieties is crucial for achieving high returns. Varieties such as Fengxiang, Saga Suixiang, Gu Nugan, Zhang Ji, Tudela, Xingxiang, and Bengwengv have shown excellent adaptability to Guangdong and Guangxi climates. They not only offer high yield and quality but also exhibit early flower bud differentiation, early flowering, and early fruit ripening, along with strong disease resistance.
2. **Using High-Quality Seedlings**: Healthy, large seedlings with sufficient nutrient reserves ensure higher survival rates after planting, faster root development, and stronger resistance to pests and diseases. Ideal seedlings should be short and sturdy, weigh over 25 grams, have well-developed roots, and possess 4–5 healthy leaves. Virus-free seedlings produced through tissue culture can increase yields by 15%–30%.
3. **Planting at the Right Time and Spacing**: Planting strawberries in late September to mid-October (when average daily temperatures are around 25–26°C) ensures adequate vegetative growth before flowering. A double-row triangular planting pattern with spacing of 18–20 cm between plants and 30 cm between rows, covering 7,400–8,200 plants per acre, helps maximize yield and early fruiting.
**II. Ensuring Successful Planting and Reducing Seedling Mortality**
Strict attention to planting techniques is essential. First, the planting depth should be just above the soil surface to avoid root exposure. Shallow planting achieves a survival rate of up to 99.5%. Second, watering immediately after planting and using shade nets help reduce stress. On sunny days, it’s important to water and shade in rotation. Third, long-distance or overnight seedlings should be dipped in yellow mud before planting to enhance survival. Lastly, consistent irrigation in the first week after planting ensures proper establishment.
**III. Efficient Fertilization Techniques**
Applying basal fertilizer effectively supports plant growth and reduces the need for frequent top-dressing. However, over-application can cause fertilizer burn. The author implemented a layered fertilization method—using either “sandwich†or “shallow ditch†techniques. The “sandwich†method involves placing compost and fertilizer in the middle of the bed, avoiding direct contact with seedlings. This method increases survival rates to 99.5%. The “shallow ditch†method applies fertilizer in shallow trenches between rows, improving efficiency and reducing labor.
**IV. Using Plastic Mulch to Reduce Labor**
Mulching with black or silver-black film improves moisture retention and suppresses weeds, significantly reducing manual weeding. It should be applied in mid-to-late November in Nanning, Guangxi, to avoid issues like root overheating or poor insulation. Transparent films are not recommended due to increased weed growth.
**V. Integrated Pest and Disease Management**
Key diseases include leaf spot, powdery mildew, gray mold, and root rot, while pests like red spider mites and aphids are common. Prevention starts with crop rotation, using resistant varieties, and maintaining good field hygiene. Early intervention with low-toxicity, high-efficiency pesticides is essential to control outbreaks effectively and minimize costs.
**VI. Enhancing Fruit Quality Through Proper Flower and Fruit Management**
Proper management of flowers and fruits is critical. Removing weak or malformed blossoms and fruits helps improve fruit size and quality. Thinning should be done carefully, leaving about 12–15 fruits per plant. This reduces deformities and enhances marketability.
**VII. Timely Harvesting and Post-Harvest Handling**
Harvesting at the right maturity stage is vital to maintain quality and reduce spoilage. Strawberries should be harvested when they are 80–90% ripe, depending on the season. During hot periods, harvesting at 70–80% maturity is advisable. Careful picking and immediate grading and packaging in transparent containers help preserve quality and increase commercial value.
