摘　　要：近年来随着农业机械化水平的快速提高,土壤机械压实问题越来越突出。通过分析土壤机械化耕作对土壤容重、坚实度、孔隙度、地表水分渗透、土壤含水率等特性的影响,阐述了农田机械化耕作后引起的土壤结构变化,以及对甜菜生长的影响,提高甜菜产质量。在促进农业机械化发展的同时,应切实考虑其负面影响,采取切实的措施,改善土壤压实情况,确保甜菜可持续生产。In recent years, with the rapid increase of agricultural mechanization level, the soil compaction problem is becoming increasingly prominent. Through the analysis of mechanized ness, porosity, surface caused by mechanized farming on soil bulk density, firmwater infiltration, soil moisture content and other characteristics, soil structure change farming were explained, as well as sugar beet growing and production of sugar beet. While promoting the development of agricultural mechanization, mechanized farming ＇s negative effects should be seriously considered, the practical measures should be taken to improve soil compaction and ensure the sustainable production of sugar beet.
