The peroxidase（POD） activity increased by an average of 344mU⋅L-1 and 28.82 （20 mU⋅L-1 ，respectively. In contrast the content of malondialdehyde（MDA） decreased by 45.28nmol⋅L-1 and 495 nmol ⋅L-1 ，respectively. Studies have shown that aerated irrigation has a wide range of application potential in salinized areas.
