Burdock, also known as Chinese burdock or arctium, is an annual herb belonging to the Compositae family. It is widely used in traditional medicine for its ability to dispel wind, clear heat, detoxify the body, and promote circulation. While the entire plant is utilized, the root is the most commonly used part, especially in culinary applications. Burdock is considered a nutritious vegetable, often referred to as a "pollution-free" food. In many developed countries, adults consume approximately 100 kilograms of burdock annually, making it a staple in daily meals. As awareness of its health benefits grows, so does its popularity, offering promising potential for agricultural development.
**First, Biological Characteristics**
1. **Botanical Features**: The burdock plant typically reaches a height of 1-2 meters. It has a deep, fleshy main root that is grayish-white in color. The leaves are alternate, long-stalked, and egg-shaped with a rounded tip. The inflorescence is tufted at the top of the stem, and the flower is tubular with purple petals. Flowering occurs from June to July, while fruiting takes place from July to August. The time from flowering to seed maturity is about 30-40 days. The 1000-seed weight ranges between 12-14 grams, and the seeds remain viable for 3-5 years.
2. **Biological Traits**: Burdock is adaptable, thriving in warm temperatures and showing good heat resistance. However, it is not very cold-tolerant. Seeds germinate best at 20-25°C, and the optimal growth temperature is also 20-25°C. The above-ground parts may die in winter, but the roots survive and regrow in the following spring. Burdock is a long-day plant, requiring sufficient light and day length to develop properly. It thrives in warm conditions, and its fleshy roots grow rapidly and become full under these circumstances.
**Second, Cultivation Practices**
1. **Site Selection and Preparation**: Burdock prefers well-drained, loose, and deep sandy soil. The soil should be rich in organic matter, with at least one meter of depth to accommodate the long roots. If the soil is too loose, it may lead to hollow roots and poor nutrient absorption. Applying 2000-3000 kg of compost per acre is recommended to ensure good growth.
2. **Sowing**: Burdock can be sown twice a year—once in mid to late April for spring planting and again in August to September for autumn planting. Sow approximately 200 grams per acre, with rows spaced 90 cm apart. Plant 9000-10,000 seedlings per mu (about 667 square meters), placing each seed 7-10 cm deep. Soak the seeds in fresh water for 10-24 hours before sowing, and keep them at 25°C for two days before planting. Germination usually occurs within 7 days.
3. **Field Management**:
- During the seedling stage, burdock requires consistent moisture. Keep the soil moist, especially in spring.
- Thin out the seedlings, leaving one per hole.
- Apply a mixture of thiophanate-methyl and foliar fertilizer during the early growth phase to prevent damping-off and encourage healthy development.
- Once new leaves appear, remove any dead leaves. When 4-5 new leaves have developed, apply 10 kg of urea per acre and water regularly. Avoid overwatering in summer to prevent root rot.
- For pest control, diseases like blight can be managed using bactericides such as carbendazim or thiophanate-methyl. Root rot can be prevented with lime milk. Aphids can be controlled using omethoate as a pesticide.
**Third, Nutritional Value and Health Benefits**
Burdock is rich in essential nutrients and offers numerous health benefits. It helps improve blood circulation, reduce the risk of hypertension, heart disease, and cerebrovascular disorders, and may even help lower blood sugar levels. Additionally, it aids in alleviating stomach cramps and promotes skin health, contributing to overall well-being. Its versatility and nutritional profile make it a valuable addition to a balanced diet.
Viral Transportation Medium Tube
Uses: used for the detection and sampling of influenza, hand, mouth, foot and other epidemic diseases
Inspection principle:
The combination of multiple antibiotics has broad-spectrum antibacterial and antifungal effects;
As a protein stabilizer, bovine serum albumin can increase the survival time and infection stability of the virus;
Buffers such as Hank's build a neutral environment, which helps to increase the survival time and infection stability of the virus;
Phenol red is an acid-base indicator, the discoloration area is 6.6 (yellow)~8.0 (red), and it is red at 7.2~7.4.
Steps:
1. According to the sampling requirements, use a sampling swab to collect samples.
