First, the premium white No. 1 radish. This variety is a recent selection from the company, featuring a fleshy, white root with a long cylindrical shape, measuring 20-25 cm in length and 4-6 cm in diameter. The texture is firm, juicy, and very tender, with little to no spiciness and a mild flavor. It's resistant to mosaic disease and has a growth cycle of 55-60 days. Each plant weighs between 1-1.5 kg. These radishes can be planted from November to March of the following year, either in greenhouses, sheds, or open fields once spring temperatures rise. They are less likely to crack or become fibrous, even if they mature late or if the buds start to twitch.
Second, the improved White Jade Spring Radish, introduced from South Korea. It has green leaves, a smooth white skin, and a dense, cylindrical root that doesn’t easily crack or become woody. It’s highly resistant to splitting and shows rapid swelling. With a growth period of about 60 days, it’s an excellent choice for early spring harvests.
Third, the improved Chinese White Radish, also introduced from South Korea. It features fewer leaves, a smooth root surface, and a long cylindrical shape. Like the previous variety, it’s resistant to cracking and has minimal fibrous roots. It can be harvested around 60 days after sowing, making it a reliable option for consistent yields.
Key points for growing spring radishes:
1. Sowing Date: From late August through the following year, with covered film planting recommended for November sowing. Greenhouse planting is ideal from December to January. Sowing too early may cause premature bolting, while planting too late increases the risk of pests and diseases.
2. Soil Preparation and Fertilization: Choose deep, loose, and fertile soil. Apply 2000 kg of farm manure per acre, along with 35 kg of compound fertilizer and 1 kg of boron as a base fertilizer. This ensures good nutrient availability throughout the growing season.
3. Sowing Technique: Use on-demand planting, placing 1-2 seeds per hole. Maintain spacing of 35 cm between rows and 20 cm between plants. After sowing, cover with a plastic film. Use approximately 90 grams of seed per acre.
4. Field Management: About 10 days after sowing, remove the film and thin out weak seedlings. Ensure timely watering during dry periods, but avoid waterlogging. Apply top dressing when the radishes begin to shoulder (the point where the root starts to swell). Apply 25 kg of compound fertilizer per acre with irrigation. A second round of fertilization should follow two weeks later, using the same amount as the first application.
5. Pest and Disease Control: Common pests include aphids, thrips, and vegetable caterpillars. Diseases such as black spot and downy mildew may occur. Localized treatments should be applied based on specific conditions and symptoms observed in the field.
