How to cultivate pepper seedlings in greenhouse cultivation

How to Successfully Cultivate Pepper Seedlings in a Greenhouse Greenhouse cultivation is an effective method for growing pepper seedlings, allowing farmers to bring their products to market earlier and significantly boost economic returns. To ensure successful seedling development, several key steps must be carefully followed: 1. **Choose the Right Nursery Site** Select a high-elevation area that is well-drained, sunny, and not prone to waterlogging. The soil should be loose and free from previous plant diseases or pests. Avoid areas with heavy clay or poor drainage, as these can hinder root development. 2. **Prepare the Seeds Properly** Before sowing, it’s essential to treat the seeds to improve germination. Soak them in warm water (60–65°C) while continuously stirring until the temperature drops. Let them soak for 8–10 hours to allow full hydration. Afterward, place the seeds in a warm environment (28–30°C) to encourage germination. Once 60–70% of the seeds have sprouted, they are ready to be planted. 3. **Control Temperature During Germination** After planting, cover the seedbeds with a layer of plastic film to maintain warmth. Keep the daytime temperature between 28–30°C and nighttime temperatures around 15–18°C. Remove the plastic film once the seedlings emerge to prevent overheating and promote healthy growth. 4. **Transplant Seedlings at the Right Time** When the seedlings have developed 2–3 true leaves, they should be transplanted. Space them about 10 cm apart in rows. Be careful not to damage the roots during the process. Maintain a daytime temperature of 26–30°C and nighttime temperatures of 15–18°C. Ten days before final planting, begin hardening off the seedlings by gradually increasing ventilation to acclimate them to outdoor conditions. 5. **Use Rooting Agents for Better Growth** Applying a rooting agent like "Root Seedling Strong" can greatly benefit the seedlings. It helps increase germination rates, promotes stronger growth, and improves resistance to disease and environmental stress. This product also helps prevent leggy growth and extends the harvest period. **Application Methods:** - **Seed Sowing:** Dilute 50 ml of the product in 10–20 times water and mix it into 50 kg of nutrient-rich soil or apply it directly to the seedbed (4–5 ml per square meter). - **Seedling Stage:** Dilute the product 30 times and apply 5–10 kg per square meter through watering or spraying. - **Transplanting:** Dilute the product 500 times and use it for watering or root dipping to speed up root establishment. By following these steps, growers can ensure strong, healthy pepper seedlings that are well-prepared for transplanting and eventual high yields. With proper care and attention, greenhouse-grown peppers can reach the market faster and provide better profitability.
