How to cultivate pepper seedlings in greenhouse cultivation

Growing pepper seedlings in a greenhouse is an effective method to advance the market season of peppers and significantly boost economic returns. Proper nursery management is crucial for successful cultivation. Here are the key steps to follow: First, choose an appropriate nursery site. It should be on higher ground, well-lit, with good drainage, and not prone to waterlogging. Avoid areas where previous crops might have left residual pathogens or pests. Next, prepare the seeds properly. Before sowing, soak them in warm water at 60–65°C, continuously stirring until the temperature drops. Let them soak for 8–10 hours to ensure they absorb enough moisture. After soaking, place the seeds in a warm environment (28–30°C) to encourage germination. Once about 60–70% of the seeds have sprouted, they are ready to be planted. Temperature control is essential during the early growth stages. After planting, cover the seedbeds with a layer of plastic film. Maintain daytime temperatures between 28–30°C and nighttime temperatures around 15–18°C. Remove the plastic as soon as the seedlings emerge. Timely transplanting is important. When the seedlings have developed 2–3 true leaves, carefully separate them, keeping a spacing of 10x10 cm. Be careful not to damage the roots during this process. Keep the temperature in the seedbeds at 26–30°C during the day and 15–18°C at night. About 10 days before transplanting, start ventilating and hardening off the seedlings to help them adapt to outdoor conditions. Using a root-stimulating agent can greatly improve seedling health. Products like Root Seedling Strong can enhance root development, promote earlier germination, and strengthen weak seedlings. During planting and transplanting, it helps seedlings establish quickly and enter the high-yield phase sooner. It also prevents leggy growth, extends the harvest period, and improves resistance to diseases and environmental stress. Application methods include: - For seeding: Dilute 50 ml of Root Seedling Strong in 10–20 times water and mix into 50 kg of nutrient soil, or use 4–5 ml per square meter in a seedbed. - During the seedling stage: Dilute 30 times and apply 5–10 kg per square meter by watering or spraying. - At transplanting: Dilute 500 times and apply to the roots. By following these steps, you can ensure healthy, vigorous pepper seedlings that are well-prepared for transplanting and ultimately lead to a more productive and profitable harvest.
