随着田间作业机械化的发展,出现了大型的农机具,它们具有省工、省时、作业效率高、相对节省油料、降低成本的优越性。但是大型农机具作业也带来了田间土壤被压实的负效果。国营农场观时正值农机具更新换代的时期,需要研究农机具—作物—作业方法—土壤管理的关系以及形成土壤压 With the development of mechanization of field operations, large-scale farm machinery has emerged. They have the advantages of labor-saving, time-saving, high operation efficiency, relatively saving fuel and reducing costs. However, the operation of large-scale agricultural machinery has also brought negative effects of compaction of the soil in the field. During the time when the state-owned farms were in the process of upgrading their farm machinery, it was necessary to study the relationship between farm machinery, crops and operating methods, and soil management, and the formation of soil pressure
