Seed processing method
1, low temperature treatment, also known as frozen processing, commonly used in melons and eggplant vegetables. The method is: The seeds that will germinate after bloating are frozen at a temperature of about 0° C. for 1 to 2 days, and then sown to promote germination and enhance the cold resistance of the seedlings.
2, temperature change processing. The tomato or cucumber seed to be germinated is placed at a relatively low temperature of 1 to 5°C for 12 to 18 hours per day, and then transferred to a high temperature of 18 to 22°C for 12 to 16 hours, and thus repeated for several days. Significantly increase the cold resistance of vegetable seedlings and accelerate their growth and development.
Low-temperature hardening method
1, about 10 days before the planting of seedlings, strictly control the watering, and gradually increase the ventilation, the seed bed temperature dropped to 15 ~ 20 °C during the day, night (cucumber, pepper, eggplant, etc.) dropped to 5 ~ 10 °C (for Robust tomato seedlings can be reduced to 1 to 5°C).
2. Remove all coverings 3 to 4 days before colonization. In this way, the seedlings can be better adapted to the open environment after colonization, which will help shorten the seedling period and increase the survival rate.
