1 Introduction
Corn is the most high yield cereal and its production
increases almost every year in the world. Of the
various corn stover components that are collectible from
the field in a typical corn harvest, stalks dominate the
available biomass[1]. On dry mass basis, about 56% of
the total stover dry mass resided in the stalk[2]. For sustainable
development of agriculture, the cutting of corn
stalk is a fundamental process in conservation tillage
that demands appropriate amount of stalks are shattered
and put back to the field to promote the yield of corn and
protect the field[3–5]. For alternative energy source, corn
stalk as a type of biomass has been widely recognized as
a clean and renewable energy source with increasing
potential to replace conventional fossil fuels in the energy
market[6,7].
