Agricultural Research Round-Leaf Lettuce Seeds - Rich flavor, cold tolerant, suitable for multi-season cultivation

Overview
Agricultural Research Round-Leaf Lettuce is a high-quality leafy lettuce variety developed for modern cultivation. The plants reach about 28 cm in height, with round leaves approximately 5 cm wide. Both stems and leaves are oil-green, soft in texture, and rich in flavor. This variety combines cold tolerance with moderate heat resistance and exhibits low susceptibility to pests and diseases, making it suitable for temperate climates. The optimal germination temperature is 10–25°C. In high-temperature seasons, low-temperature germination treatment (e.g., refrigeration or well-hanging methods) is required to promote sprouting. Direct seeding with shade netting is recommended in summer, while transplanting is suitable for autumn. With proper cultivation, this variety ensures stable yields and excellent quality.

Key Features
• Unique Round-Leaf Morphology: Round, broad leaves with an attractive oil-green appearance and soft texture, ideal for fresh consumption and processing.
• Strong Stress Resistance: High cold tolerance, moderate heat resistance, and reduced susceptibility to common pests and diseases, lowering cultivation risks.
• Rich Flavor: Leaves are aromatic with a delicate taste, suitable for salads, stir-fries, and various culinary uses.
• Multi-Season Adaptability: Can be cultivated in spring, summer, and autumn with temperature management, requiring shade measures in high-heat seasons.
• Cultivation Flexibility: Supports both direct seeding and transplanting methods, with 12×14 cm spacing to optimize space utilization.

Cultivation Guidelines
• Temperature Management: Optimal germination temperature is 10–25°C. In high temperatures, use low-temperature germination treatment (e.g., 5–10°C refrigeration for 24–48 hours) to prevent germination difficulties or bolting.
• Sowing Method: Direct seeding with shade netting is recommended in high summer temperatures; transplanting is suitable in autumn with a spacing of 12×14 cm.
• Water and Fertilizer Management: Keep soil moist but avoid waterlogging. Apply balanced liquid fertilizer every 2–3 weeks during the growth period to promote leaf development.
• Pest and Disease Control: Regular inspections are advised. Use biological agents for minor pest issues and avoid continuous cropping to reduce disease risk.
• Harvest Timing: Harvest in batches when plants reach 25–28 cm in height, retaining the base to encourage lateral regrowth.
