Abstract: The experiment was carried out by three tillage methods of first year strip deep totary tillage （TX）,second year exchange row strip deep totary tillage （GTX） and the conventional shallow tillage （ck）.Through measured the soil compaction,the density of dry root weight,tile diameter of root,the density of root length,the density of root superficial area and the yield,and so on, revealed the effect of strip deep totary tillage on the soil compaction and root characters.The results showed that TX and GTX can effectively broke the plow pan,reduced soil compaction for 10.0-27.5cm soil layer, and increased the distribution of dry root weight,root length and root superficial area for 15-60cm soil layer,and lowered the diameter of root,and increased the yield by 19.68% and 24.35%,respectively.
