First, prepare a nutrient-rich soil mix that has been used for the past three years. Use 60% garden soil from cucurbit crops and 40% organic fertilizer, which includes 30% compost and 10% wood ash. Additionally, add 0.2% diammonium phosphate or 1 kg of superphosphate per cubic meter of rice nutrition soil. Before use, mix the soil with 800 times diluted thiophanate-methyl to prevent fungal diseases. Next, create the seedbeds in a well-lit area. If possible, use electric heating cables, placing them at 100 watts per square meter. Fill each container with 80% of the prepared nutrient soil, and arrange the pots neatly on the seedbed to ensure even growth. For seed treatment, dry the seeds in the sun for 2-3 days. Soak them in a 500-600 times diluted carbendazim solution for 24 hours, then rinse them thoroughly. Finally, soak the seeds in water at 50-55°C for 3-4 hours to enhance germination. After soaking, remove the seeds from the water and wrap them in a damp cloth. Place them in a warm area (25-30°C) to encourage germination. Once about 80% of the seeds have sprouted, they are ready to be sown. When sowing, first water the seedbed thoroughly. Then place the germinated seeds into individual planting holes, cover them with 1-1.5 cm of fine sifted soil, and apply a layer of mulch to retain moisture and warmth. Once the seedlings emerge, gradually remove the mulch to avoid overheating. Seedbed management is crucial for healthy plant development. During the germination phase, maintain daytime temperatures around 30°C and nighttime temperatures above 20°C. After the seedlings emerge, lower the temperature to 25°C during the day and 14-16°C at night. Once true leaves appear, keep the temperature between 22-25°C during the day and 13-15°C at night. Seven days before transplanting, begin hardening off the seedlings by reducing the temperature further. In addition to temperature control, avoid overwatering throughout the growing period. Water only when necessary, preferably in the morning on dry days. Ensure sufficient light exposure and monitor regularly for pests and diseases. Prompt action can prevent major issues and promote strong growth. Strong seedlings should be 10-15 cm tall, with one main stem, sturdy and disease-free. They should have short internodes, thick stems, dark green leaves, and well-developed roots. The ideal age for transplanting is around 35 days. This method ensures healthy, vigorous plants ready for field planting.
