摘　　要：深松技术是旱地保护性耕作体系的重要技术措施之一。随着保护性耕作技术的推广,深松技术在改善耕层土壤结构、提高土壤蓄水抗旱和渗透能力方面起着重要作用。当前,国内外学者对深松技术和相应的深松机具进行了大量的研究,并取得了较大的成果。为此,介绍了深松技术、相应深松机具、深松铲的类型和特点,并对现有深松铲的结构改进和优化、改善深松部件与土壤接触时的抗磨损性及减阻性能的措施和研究现状进行了总结。同时,分析了影响深松技术提高的影响因素,提出了进一步研究和改进深松技术的思考和建议。Mechanized subsoiling, which is effective in improving soil structure and enhancing soil water-holding capaci-ty, has been widely promoted in dry land farming areas in northern China.This article summarized current subsoiling technology and characteristics of subsoiller.It presented current studies on the structural optimization of existed subsoiling shovels, and the techniques of wear-resistance improvement and penetration-resistance reduction for subsoiller.Further-more , the factors that affect subsoiling’ s effects were analyzed, and the suggestions for future research of subsoiling tech-nology were proposed in this study.
