摘要 为了解玉米免耕技术发展的情况,为该技术的研究和推广提供参考,从3个方面综述了玉米免耕机理的研究进展:1)玉米免耕对土壤理化性状的影响,主要包括土壤结构、气体排放、pH值、水分、微生物、温度、养分以及土壤酶活性等;2)玉米免耕对根系、植株生长和产量的影响;3)玉米免耕对经济效益的影响。并指出玉米免耕机理的研究空白领域以及玉米免耕具有两面性的特点。 To know the development status of no-tillage technology of maize and to provide a reference for its research and extension,research progress in no-tillage mechanism of maize was reviewed from three aspects: 1) Effect of no-tillage on soil physics and chemistry characters which included soil structure,gas emissions,pH,moisture content,microorganism,temperature,nutrient as well as soil enzyme activity;2) Effect of no-tillage on corn root system,plant growth and yield of maize;3) Effect of no-tillage on economic efficiency.The blank research domains and dual characters of no-tillage maize were also put forward in this paper.
