回顾了近几十年来国内外尤其是欧美等机械化发达国家在土壤机械压实危害方面的研究成果。土壤机械压实危害主要表现在土壤容积质量和机械阻力增加,大孔隙减少,土壤物理、化学、生物性状恶化,进而影响作物的生长发育,土壤结构发生退化,已成为当前制约农业可持续发展的障碍因素之一。 The research results of mechanical compaction hazards of mechanized developed countries at home and abroad, especially Europe and the United States, have been reviewed in recent decades. Soil compaction hazards are mainly manifested in the increase of soil volumetric mass and mechanical resistance, the reduction of macropores, the deterioration of soil physical, chemical and biological properties, which in turn affect the growth and development of crops and the degradation of soil structure, which have become the current constraints on the sustainable development of agriculture One of the obstacles.
