摘      要：Subsoiling has been widely used all over the world as an important operation method of no-tillage *** energy-saving and life-extension,the tillage resistance and wear-corrosion of subsoilers have attracted wide *** this study,the tillage resistance,soil disturbance,wear and corrosion of subsoiler with S-T-SK-2#biomimetic structures(S means subsoiler;T means tine;SK means shank;2#,h/s=0.57,h=5 mm andα=45°.)and self-healing coating under two seasons,two locations with different soil properties(black loam and clay soil)and subsoiling speeds(2 km/h and 3.6 km/h)were *** soil moisture content and compactness affected the tillage resistance and *** tillage resistance and degree of corrosion on all subsoilers were much larger in clay soil than that in black loam *** with S-T-SK-2#,the tillage reduction rate of C-S-T-SK-2#(S-T-SK-2#with self-healing coating)was up to 14.32%in clay soil under the speed of 2 km/*** significance tests of regression equation results showed that subsoiler type and soil properties had a significant impact on soil disturbance coefficient,swelling of total soil layer,bulkiness of the plough *** is of a guiding significance for the analysis of soil *** mechanism of subsoiler coupling with biomimetic structures and self-healing coating was analyzed in *** depicted the guiding effect of biomimetic structure and the shield function of self-healing coating,resulting in anticorrosion and wear resistance of subsoiler.
