Abstract: In view of the shortage of traditional seed treatment technology, vacuum UV was generated by plasma glow discharge to activate the vigor of seeds and improve the seed resistance and crop yield. The key discharge technology of plasma seed activation equipment at home and abroad was compared and studied, and the automatic production line of plasma activation was developed to realize continuous production of plasma activation treatment for agricultural seed. The production technology of plasma activation for agricultural seed and the application research of demonstration base were also discussed. The results showed that the activation treatment had good repeatability, increased yield and enzyme activity, advanced harvest time, fast processing speed and high production efficiency. The plasma activation production line and its production technology provided a good paradigm for seed activation intelligent treatment.
