Abstract:

Premature senescence may induce reduction of the corn yield and severely degrade the corn quality. At present, solving premature senescence becomes a research emphasis for many agriculturists. Based on deep plow pan layers existed in agricultural production, This review summarizes advance in the regulatory effect of subsoiling in breaking plow pan layers on delaying premature senescence of corn. The overview concludes the relationship between root and aboveground part of corn, influences of subsoiling on soil water storage capacity, soil bulk density, soil enzymatic activity and rhizosphere microorganisms as well as root growth and development and so on. At the same time, a prospect for solving premature senescence of corn in terms of cultivation and farming is presented in this article, which may provide a help for solving this problem.
