The invention relates to a plasma crop seed treatment production line and a production technology of the plasma crop seed treatment production line. The plasma crop seed treatment production line comprises a plasma discharge vacuum container, an automatic feeding mechanism, an automatic discharging mechanism, a conveying mechanism and an electric control cabinet. After crop seeds enter a feeding container, impurities are removed after the crop seeds are vibrated, the crop seeds enter the electrode of the vacuum container for plasma processing, and the processed crop seeds enter a discharging container, are conveyed to the conveying mechanism through the automatic discharging mechanism and are packed and encased through a mechanical arm. The plasma crop seed treatment production line is suitable for plasma processing of different crop seeds such as wheat seeds, the processing result is good in repeatability, the structure is reasonable, stability is good, automatic control over the production is achieved, manual intervention is avoided, labor intensity is relived, the machining cycle is shortened, and production efficiency is improved.
