In order to research the effects of minimum tillage and no-tillage patterns on yield and senescence of flag leaf of winter wheat, four tillage patterns were adopted in Longkou city, Shandong Province, China for three years. Four tillage patterns were as follows: conventional tillage with straw turnover, rotary tillage with straw turnover, serrated disk harrow tillage with straw turnover, no-tillage with straw cover. Effects of different tillage patterns on the activities of superoxide dismutase, peroxidase and the contents of malondialdehyde and soluble protein of the winter wheat flag leaves after anthesis were analyzed.
