A pot experiment was designed under drought stress condition to study the effect of different nitrogen levels on lipid peroxidation and protective enzyme activities in the leaves of relay strip intercropping soybean. The activities of superoxide dismutase (SOD), peroxidase (POD), catalase (CAT) and the content of malondialdehyde (MDA) were measured. Results showed that under the drought stress condition, activities of SOD, POD, CAT, content of MDA were significantly increased when drought happened, and the value increased as the degree of drought stress became severely. Nitrogen application could reduce MDA content, increase SOD, POD, CAT activities, and then the membrane lipid peroxidation was reduced. The effects of different nitrogen application levels are different. Appropriate nitrogen fertilizer can increase the activity of enzyme and reduce the content of MDA, but much too high nitrogen treatment will be contrary.
