Abstract: Abstract: Test in Wuchuan County in Inner Mongolia, the northern foot of dry farmland Yinshan .It carried out by Traditional Tillage as a comparison study of No-tillage, Annual Subsoiling, Annual Asamatsu, Light Rotation ,Subsoiling over year, six tillage treatment on weeds control and oat yield. The results showed that: ① It contains large proportion of monocotyledonous weeds in farmland. mainly Setaria viridis, wild oats, etc., all of them are the grassy weeds, accounting for 81.7%; Others for the dicotyledonous weeds, mainly Salsola, Chenopodium album, Artemisia annua, etc. which contains eight kinds of weeds, accounting for 18.3% of all the weeds. ②No-tillage, Annual subsoiling, Following year subsoiling in the frequency of large weeds, shallow loose and shallow rotary on the weed control is relatively good, no-tillage weed density than shallow loose, the traditional increased 42.4%, 22.1%. ③ Combination of herbicides with different tillage strains of anti-efficiency and the fresh weight control effect of glyphosate are the highest, respectively, 76.3% ~ 82.1% and 79.3% ~ 93.2%. ④ In addition to Light Rotation, all the other farming methods yields were significantly higher than traditional farming.
