what is Food safety and Quality services?
1. Regulatory Advisory and Compliance Services: Provide advice on national and international food safety regulations, standards and guidelines to help food companies understand and comply with relevant legal requirements.
2. Risk assessment and management: Identify and assess possible food safety risks in the food production chain, and develop and implement a risk management plan to reduce these risks.
3. Laboratory testing and analysis: Provide chemical, microbiological, physical and sensory testing and analysis services for food samples to ensure food quality and safety.
4. Supply chain monitoring and traceability: Through advanced technology and systems, real-time monitoring and traceability of the food supply chain to ensure traceability and transparency of the product source.
5. Education, training and capacity building: Provide food enterprises and related personnel with food safety and quality management training and education to improve their knowledge and skills.
6. Technical support and research and development: Provide technical support and research and development services for specific food or production process, including new product development, production process improvement and food safety technology research and development.

Boxwood is a southern evergreen tree species belonging to the Cyclovirobuxaceae family. For many years, it has been highly favored for its compact, leafy, and evergreen characteristics, making it a popular choice in landscaping. It's widely used for hedges, topiaries, and ornamental plantings. In northern China, boxwood is one of the most commonly used trees in landscape design. However, due to climate differences, it has been challenging to grow boxwood seedlings in the north. As a result, green seedlings are often transported over long distances from the south, which increases costs and reduces survival rates.
To address this issue, we carefully reviewed our experiences and lessons learned in boxwood propagation. We adjusted the timing of cuttings from winter to summer, changed the soil medium to a stone-based mix, and used young shoots instead of old branches. These changes created a more favorable environment for growth. After extensive testing, we developed an effective cutting technique that has now been successfully applied on a large scale in northern China. The survival rate exceeds 85%, and the process is easy to implement. This breakthrough has significantly improved the availability of boxwood seedlings in the region. Last year, we successfully produced 400,000 seedlings using this method. Here are the detailed steps:
**1. Cutting Bed Preparation**
The cutting bed should be located in a well-ventilated and well-drained area. The bed should be 1 to 1.2 meters wide, with 0.5 to 0.6 meters between each row. The bed should be built with vertical bricks around the edges, and the surface should be leveled and filled with a suitable substrate. The working area should be paved with bricks for better access.
For the substrate, a mix of crushed stone and sand with good drainage and aeration is ideal. A 4–5 cm layer of this mix is recommended, with a 2 cm layer of coarse sand at the bottom for additional drainage.
Shading is essential during the growing season. A 65% shade net or a solar greenhouse can be used. If no greenhouse is available, bamboo frames or steel structures can be set up. The structure should be sturdy enough to support winter cover.
A micro-sprinkler system is crucial for maintaining humidity and cooling. Nozzles should be evenly distributed to avoid dry spots. An automatic misting system is preferred, but manual control is also acceptable.
**2. Cutting Techniques**
Cutting should take place between mid-May and early August, ideally just before or after the peak of new growth.
Choose healthy, young plants (1–5 years old) that are vigorous and free from pests. Cuttings should come from semi-hardened branches of the current year or robust two-year-old branches. Avoid using branches older than three years.
Harvest cuttings in the early morning or late afternoon to reduce water loss. After cutting, place them in the shade. Each cutting should have 4–5 cm of base with leaves, and 2–3 leafy shoots at the top. Leave 5–6 cm of the tip to encourage rooting. Wounds from trimming help stimulate root formation. After preparation, bundle 30–50 cuttings together and place them in a container with 2–3 cm of clean water.
**3. Planting the Cuttings**
Before inserting, ensure the base is fully moistened. Treat the cuttings with a 500 g/kg rooting hormone solution.
Space the cuttings 4x4 cm or 5x5 cm apart, or even 2x2 cm if space allows. Insert them 4–5 cm deep into the substrate, and gently press the soil around the base to secure them.
**4. Post-Insertion Care**
Maintaining proper humidity is critical. The substrate should stay moist at 15–25%, and air humidity should remain above 70%. Adjust misting frequency based on weather and root development. In hot weather, increase misting, but reduce it during rainy days or early/late hours. Once rooted, gradually decrease watering. Drain excess water after heavy rain to prevent rot.
Pest control is important due to high humidity. Spray carbendazim or chlorothalonil every two weeks. If pests appear, treat them immediately.
If not transplanted in the same year, apply a 0.3–0.5% urea or compound fertilizer spray every 15 days.
If planted in the same year, remove the shade net and gradually reduce watering after two months to acclimate the seedlings to outdoor conditions.
