Abstract：The effects of 3 tillage methods including conventional tillage , rotary tillage and no-tillage, and straw returning on wheat growth and yield were studied .The results showed that the leaf area index was higher at early growth stage of wheat under conventional tillage and at late growth stage of wheat under no -tillage.The plant height of wheat was reduced by rotary tillage and no -tillage.The dry matter accumulation of wheat under rotary tillage and no -tillage decreased by 7 .2%and 17 .7%respectively compared to conven-tional tillage.The yield of wheat under rotary tillage and conventional tillage were not different obviously , and it was reduced by 10.8% under no -tillage.Straw returning could increase yield of wheat ,especially under rotary tillage treatment,which was increased by 9.8%.
