Abstract:: 10 tomato varieties were used as materials，different rhizosphere hypoxia stress on SOD of hydroponics tomato were carried out，in order to promote hydroponic tomato technology in large scale，to solve hydroponic tomato cultivation in the root zone hypoxia problem.The results showed that，the rhizosphere in the early hypoxic hypoxia stress could promote the activity，activity increased in the rhizosphere hypoxia with time decreased；different tomato varieties and hypoxic environment in the rhizosphere caused different degree of reduced activity，and there were differences among varieties.Under hypoxic conditions rhizosphere，tomato variety ‘Zimeigui’ had strong SOD activity，variety ‘Danhong F1’had weaker SOD activity.
