This cultivation method has a long harvest period, and the main growth period is at a low temperature. Under weak and warm conditions, it is required that the greenhouse has strong heat preservation or heating equipment; the varieties that are resistant to low temperature, low light and strong growth potential are also used for grafting technology.
