Research Status on Mechanized Subsoiling Technology in Northern China
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.
