1. Seed treatment: Soak seeds before drying for 1 to 2 days, then soak in 1% potassium permanganate solution for 30 minutes, remove and wash. Then soak seeds in warm water of 5 to 6 times the seed volume for 10 to 15 minutes at 50°C to 55°C. Stir constantly and soak for 8 to 10 hours at about 30°C. Remove the mucus from the surface of the seeds with fine sand meal. The treated seeds were wrapped in a wet cloth and germinated under conditions of about 30°C. During germination, wash it with clean water once a day, usually 5 to 7 days to germinate. Seeds when more than 70% of the seeds are white.
2. Pre-planting preparation: Mix 60% of fertile paddy soil and 40% of pig manure that have not been planted in solanaceous vegetables as a culture soil, plus an appropriate amount of ternary compound fertilizer and 25% of carbendazim 1 . Then make a seedbed with a bed 1.2 meters wide. When necessary, cover a hotline of 80 to 100 watts per mu, then lay 10 centimeters thick nutritious soil on top of it, and pour water to prepare for sowing.
3, sowing: sowing election on a sunny morning, the budding seeds are evenly sprinkled on the surface, cover a 1 cm thick nutrient soil, back cover film. The temperature during the day before emergence is maintained at 25°C to 30°C, 16°C to 20°C at night, and about 20°C at ground temperature. Generally, 5 to 6 days can be used to produce seedlings, and 70% of the seedlings are removed from the mulch after emergence.
4. Seedling management: After the seedlings are properly reduced, the room temperature should be 20°C～ 25°C during the day and 15°C at night. Sprinkle the dry nutrient soil to the seedbed to prevent unearthing with the cap. The two cotyledons should be fully spread and then sprinkled once. Thickness 0.3 to 0.5 cm. When the seedling grows to two leaves and one heart, separate the seedlings by means of 10 to 15 centimeters to open a small ditch, water in the ditch, swing it apart by 10 centimeters, and then cover the nutrient soil. After sub-seedlings, heat preservation is strengthened and the temperature is 28°C to 30°C during the day. 16°C to 20°C at night. When the heart of the seedlings begins to grow, the daytime temperature is controlled between 20°C and 25°C and at night between 13°C and 15°C to prevent leggy growth. About 10 days before planting, the seedlings are planted, about 20°C during the day and about 12°C at night.
