Abstract: The present disclosure discloses a tobacco leaf foliar spraying substance for reducing harmful ingredients in cheroot, a method for reducing carcinogenic components in flue-cured tobacco leaves and flue-cured tobacco shreds. The tobacco leaf foliar spraying substance contains a lotus leaf extract, the harmful chemical ingredients comprise N-nitrosonornicotine, 4-(N-methyl-nitrosamine)-1-(3-pyridinyl)-1-butanone, N-nitrosoanabasine and N-nitrosoanatabine. Foliar spraying is performed on a fertile field by using the lotus leaf extract before tobacco leaves are harvested and modulated, which not only significantly promotesagronomic characters and economic traits of tobacco and alleviates tobacco leaf browning but also effectively reduces harmful chemical ingredients unique to tobacco leaves, such as nitrosamine and nicotine.

Abstract: An information processing device and a control method applied to the information processing device is described. The information processing device includes a display unit configured to display images; an input unit configured to receive inputs from a user; a motion detecting unit configured to detect motion of the information processing device and to generate data related to the motion; and a processing unit connected to the display unit, the input unit and the motion detecting unit. The processing unit is configured to receive the motion-related data from the motion detecting unit, and enable/disable of the display unit and/or the input unit based on the data related to the motion.
