T1：不施肥;T2：底肥单层条施于8 cm深处;T3：底肥单层条施于16 cm深处;T4：底肥单层条施于24 cm深处;T5：底肥按1﹕2﹕3的比例分层条施于8、16和24 cm深处。下同
Fig. 1. The activity of superoxide dismutase (SOD) and catalase (CAT), content of malondialdehyde (MDA) and soluble protein in flag leaves after anthesis under different treatments
T1 for no basal fertilize; T2 for basal fertilizer layered at 8 cm depths and in stripes; T3 for basal fertilizer layered at 16 cm depths and in stripes; T4 for basal fertilizer layered at 24 cm depths and in stripes; T5 for basal fertilizer was divided into three parts with the proportion of 1﹕2﹕3 and applied in stripes of 8, 16 and 24 cm depths of soil. The same as below
