1. Variety selection Select plant compact, plant erect, cold tolerance varieties or hybrid generation. Such as Tianjin fast round eggplant, Beijing Liu Yegu and aescinate and so on. 2. timely sowing nurturing seedling sowing age and seedling age directly affect the early maturity and high yield of eggplant. Sowing too early, seedling age, seedling is too large, slow seedling slowed after planting, affecting early maturity; sowing too late, short seedling age, less than the requirements of early maturity, suitable sowing period in Beijing in late January, strong seedling standard Is developed root system, height 18 ~ 20cm, 6 to 8 leaves, more than 70% of budding bud, stem thick, root developed.
