How to raise seedlings for winter sowing

Before sowing, the seeds are sun-dried for 2-3 days, and then soaked with warm water or pesticides. Soak the seed with warm water, soak the seed with water, then soak it in warm water of 55°C for 15 minutes. Soak the seed with the water and soak in the seed for 2 hours. Soak the seed with 75% chlorothalonil 800 times for 20 minutes and rinse with clean water. The seeds were germinated and germinated at 25-30°C until 70% of the seeds were whitened.

Seed beds should be selected to shelter from the sun, loose fertile, 2-3 years have not been planted solanaceous vegetables fields, flattening before the sowing.

Usually sowed in mid-December, with 50 grams per acre. Before seeding, the seedbed shall be poured with bottom water. Seeds shall be uniformly spread on the seedbed and compacted with a flat plate so that the seed is fully bonded with the soil. Then, 5% of the thin fertilizer water is poured, and 0.5-1 cm thick is covered on the seedbed. Nutritious soil, then covered with film or take a small shed insulation moisture. When 30% of the seedlings emerged, they were stripped of the mulching film. Qimiao seedlings after 1-2 times, post-migration and transplanted before the topdressing of a 5% manure water, seedlings to let the seedlings ventilated see light. Seedling management is mainly to control the seedlings, to avoid bed soil too wet. The nutritious soil is not white and not watered, and it is poured on water, and it is usually watered in the sunny afternoon. According to the growth of seedlings, urea or compound fertilizer can be applied in combination with watering.

Seedlings 2-3 leaves when the cold head warm sunny days with a drug zone soil planting, watering the edge of the false planting, 3-4 days before planting the appropriate hardening seedlings, strengthen ventilation, temperature 19-25 °C, night Temperature 13-15 °C. After the planting, it was covered with a small arch shed, which was kept moist for 4-5 days. The temperature inside the shed was maintained at 28°C. Spray 75% chlorothalonil 800 times or 70% mancozeb 800 times to prevent disease after prosthesis. After the seedlings, the temperature in the shed should not be higher than 25°C. The seedlings should be planted about one week before planting. The night temperature should be 13-15°C, and the water should be controlled to gradually increase the ventilation. Planting stage seedlings generally have 9-12 true leaves and begin to branch with several buds, the plants are robust, the leaves are hypertrophic, the leaves are dark green, the root system is developed, there is no pests and diseases, and the height is not high.
