The present invention makes it possible to produce a large amount of microbubble water containing a high concentration plasma to be dissolved in water in a microbubble state by generating a large amount of plasma having a high concentration nitrogen oxide in a plasma state that is commercially available, and spray it on agricultural products to store agricultural products. And it relates to a combined cultivation system for sterilization of agricultural products using a thunderbolt discharge and microbubble water for sterilization during cultivation and washing. The present invention supplies high-voltage power to the air pressure increasing means (10) having a tornado conversion means (12) for allowing external air to swirl and blow in the ventilation pipe (11) and a pair of discharge electrodes (21) in the ventilation pipe (11). Thus, a thunderbolt discharge device 100 having a discharge means 20 for generating a discharge flame (K) for generating a plasma having nitrogen oxide, and the plasma gas discharged from the ventilation pipe 11 are blown at high pressure. There is a plasma generation supply device (1) having a ring brush fan (7), and a water receiving chamber (40a) in which plasma gas is supplied and water is supplied from the plasma generation supply device (1). A microbubble water production unit 40 having a plasma bubble generating means 50 for allowing plasma gas to become a plasma bubble in the chamber 40a, and water having plasma bubbles generated in the microbubble water production unit 40 A colloid generator that is pumped through the bypass pipe 34 by the pump 45 to become microbubbles while passing through the microbubble processing chamber 63 to obtain the number of microbubbles (W) converted to OH - radicals ( 60) And, the microbubble water is supplied from the microbubble water production unit 40, and is made to be sprayed by the high-pressure spray pump 48 and the injection pipe 49 from the top of the agricultural product (S).본 발명은 상용화가 가능한
