**Begonia 'Sagittarius' (Saffron Begonia)**
**Plant Species:** Perennial small shrubs
**Common Names:** Sagittarius Begonia, Saffron Begonia
**Morphological Characteristics:**
The plant features upright stems with thickened segments that resemble bamboo. Its leaves are long and oval-shaped, with a vibrant green surface covered in numerous small white spots. The underside of the leaves is fuchsia, creating a striking contrast. The flowers are small but eye-catching, coming in bright red or pink hues. They bloom in clusters and have a long flowering period, making them ideal for indoor decoration. Their beauty and unique appearance make them a popular choice among plant lovers.
**Growth Habits:**
This begonia thrives in scattered light and is sensitive to direct sunlight, especially during the summer months. Proper care is essential to maintain its lush foliage and vibrant blooms. It is known as a four-season ornamental plant, with dark red flowers blooming throughout the year. The sturdy, bamboo-like stems and large, speckled leaves give it an elegant look that appeals to people of all ages.
**Summer Maintenance Tips:**
1. **Light Requirements:** During the summer, place the plant in a location with indirect, bright light. Direct sunlight can cause leaf tips to dry out, yellowing, and even leaf drop. A north-facing balcony or a shaded area under a porch is ideal.
2. **Avoid Dark Environments:** Prolonged exposure to low light can lead to weak growth, fewer flowers, and elongated stems. If kept in the dark for too long, the plant may suffer from yellowing leaves and eventual decline.
3. **Watering and Humidity Control:** Keep the soil consistently moist but not waterlogged. In hot, dry weather, mist the leaves and surrounding area 2–3 times daily to increase humidity and reduce temperature, which helps the plant thrive.
4. **Fertilization:** Apply a diluted organic fertilizer every 7–10 days during the growing season. Increase phosphorus and potassium when buds appear to encourage flowering, and reduce or stop fertilizing once the flowers begin to fade. Remove spent blooms promptly and prune flowered branches to promote new growth and more flowers.
5. **Pest and Disease Prevention:** High temperatures and humidity in summer can increase the risk of pests and diseases. Ensure good air circulation and avoid overwatering. Spray a fungicide like Bordeaux mixture or carbendazim every two weeks. For spider mites, use a fine mesh to trap them, and manually remove scale insects if found.
6. **Pruning:** If the plant becomes too tall or leggy, trim the top shoots to encourage bushier growth. This helps maintain a compact and attractive shape while promoting more flower buds.
With proper care, the Sagittarius Begonia will remain a stunning addition to any garden or indoor space, offering beauty and charm all year round.
Vtm Sampling Tube With Swab
[Sample requirements]
The collected nasopharyngeal swab samples should be transported at 2°C to 8°C and sent for inspection immediately, and the sample delivery and storage time should not exceed 48 hours.
[Testing method]
1. Before sampling, mark the relevant sample information on the label of the sampling tube.
2. According to different sampling requirements, use a sampling swab to sample in the nasopharynx.
3. The specific sampling methods are as follows:
a) Nasal swab: Gently insert the swab head into the nasal palate, stay for a while and then slowly turn to exit. Wipe the other nostril with another swab, immerse the swab head in the sampling solution, and discard the tail.
b) Pharyngeal swab: Wipe bilateral pharyngeal tonsils and posterior pharyngeal wall with a swab, also immerse the swab head in the sampling solution, and discard the tail.
4. Quickly put the swab into the sampling tube.
5. Break the part of the sampling swab higher than the sampling tube, and tighten the tube cover.
6. Freshly collected clinical specimens should be transported to the laboratory within 48 hours at 2°C to 8°C.
[Explanation of test results]
After the sample is collected, the sampling solution turns slightly yellow, which will not affect the nucleic acid test result.
[Limitations of the test method]
1. For samples that are seriously contaminated due to improper storage after collection, the final test results will be affected.
2. If the sample is not stored at the specified temperature, the final test result will be affected.
