This paper conducted pot experiment and studied the effects of corn stalks on
microenvironment，chemical and physical properties of the secondary salinized soil，and growth of tomato．
The results showed that adding corn stalks could enrich the microbial population in salinized soil．The
number of effective bacterial sequences in the soil microbial community was increased，and flora structure
became more abundant．The main effective flora were Enterobacteriaceae，Sphingomonadaceae，and
Xanthomonadaceae．Adding corn stalks could improve the aggregate structure of salinized soil，significantly
increase soil organic matter content，accelerate the release of mineral elements in soil facility，and reduce the
contents of alkali nitrogen，available potassium and available phosphorus in soil．With the treatment of adding
corn stalks，tomato plant height，stem diameter and photosynthetic index were significantly higher than that of
the contrast．And the tomato yield was also remarkably increased．
