The 1-3 months each year is the season of each region with the lowest annual gas temperature and illumination intensity, the least number of illumination hours and frequent cold invasion. The unfavorable climate conditions lead to that plants in various places are subjected to heat preservation and concentrated seedling raising measures, but the cultivated plants are weak due to insufficient illumination, poor in stress resistance and long in seedling stage after transplanting, so that the growth yield and quality of the plants are greatly influenced. Therefore, the temperature is low, and the insufficient illumination time is one of the main reasons that the plant quality of the tobacco areas is difficult to improve.
