Abstract:: In order to investigate the effects of different tillage methods on compaction of windy and sandy soil, four-treatment experiment involving the broken ridge, original ridge tillage, rotary original ridge tillage and no tillage was conducted in the maize field in the science and technology park of Taikang of Daqing City. The variations of soil compaction of each 5 cm in the depth range of 0—40 cm were measured at three stages including the before sowing of corn, after sowing of corn and harvesting. The results showed that rotary tillage made surface soil relatively loose, but the soil compaction below the depth of 35 cm was significantly higher than the topsoil due to mechanical operation; broken ridge made the compaction phenomenon more obvious, making the soil quality unsustainable. Rotary original ridge tillage could significantly improve soil compaction below the depth of 20 cm, and soil compaction at the depth of 0—20 cm demonstrated insignificant effect compared with the other tillage practices, which protects the surface soil from erosion and makes the root zone (20—40 cm) become loose. Therefore, the rotary original tillage practice deserves widespread application.
