The traditional cultivation method of lettuce in Nanchang City is transplanting of winter sowing seedlings and harvesting in spring. No lettuce supply during September-October autumn season. In order to increase the varieties of off-season vegetables, I and the suburbs of Nanchang City, some brigade, production team vegetables research group planted autumn lettuce, basically successful.
