近年来,土地过度开垦致使土地沙漠化、干旱等自然灾害问题越来越严重,因此提出了基于保护性耕作的深松技术. 以深松技术代替铧式犁翻耕,是利用深松机具的部件在土壤不被翻转条件下疏松土壤、打破坚硬犁底层、加深耕作土层,以此来调节土壤3 相(固、液、气态)比,改善土壤内部结构,降低土壤被侵蚀度,提高土壤蓄水保墒的能力,达到高产、少耕、环保的目的,促进农业的可持续发展. 为此,主要介绍了基于保护性耕作深松技术在国内外发展现状 ,旨在为保护性耕作和深松机械的制造和发展提供一定的依据.

In recent years ,land desertification , drought and other natural disasters are becoming more and more serious with the excessive reclamation of land .In order to solve this problem ,a subsoiling technology based on conservation till-age was proposed .With the deep loosening technology instead of mouldboard plow tillage , deep loosening machines were used to loose soil , break the plow pan and deep tillage layer under the condition of not turning the soil , achieving the purpose of high yield , reduced tillage and environmental protection with regulating soil 3 phases ( solid, liquid, gas) ra-tio , improving soil structure , reducing soil erosion and improving water holding capacity .The development status of sub-soiling technique based on conservation tillage was introduced at home and abroad , providing a basis for the manufactur-ing and development of conservation tillage and subsoiling machinery .
