摘要
早衰严重影响玉米的产量和品质,解决玉米早衰问题已成为当前广大农业工作者研究的重点。结合目前生产中存在的犁底层深厚这一现状,从根系与地上部分的关系,深松对土壤蓄水量、土壤容重、根际微生物和酶活性的影响及根系生长发育等方面,综述了深松打破犁底层对延缓衰老调控作用的进展,并对今后如何从栽培和耕作学角度来研究玉米早衰问题进行了展望,以期为解决生产中玉米早衰问题提供帮助。
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.
