Abstract: The present disclosure relates to a method for activating a crop seed by high-voltage electric field cold plasma (HVCP), and use thereof, belonging to the technical field of crop planting. The present disclosure provides a method for activating a crop seed by HVCP, including the following steps: (1) mixing a crop seed with water and immersing the crop seed in water for 4 h to 24 h to obtain an immersed crop seed; and (2) conducting discharge activation on the immersed crop seed at a voltage of 80 kV to 130 kV to obtain an activated crop seed. In the present disclosure, the method can improve heat-resistant and disease-resistant properties of crops, and provide a scientific basis for subsequent acquisition of excellent seeds.

Abstract: A sterilizer includes a cold plasma generator; an ultraviolet (UV) light generator; and an airflow circulation system. The cold plasma generator and the UV light generator are disposed in the airflow circulation system. The cold plasma generator is configured to generate a cold plasma airflow; the UV light generator is configured to emit an UV light; the UV light generator is disposed in a downstream of the cold plasma airflow of the cold plasma generator, so that the cold plasma airflow is exposed to the UV light to form a disinfecting airflow that is then sprayed on a surface of a sample contaminated with a pathogen comprising coronavirus.
