Abstract：The cultivation technique with straw returning has become one of the key problems in wheat production at present.In order to further fulfill the yield increasing potential,a field located experiment was conducted in growing season of 2014 ~2015 to study the effects of tillage mode and nitrogen fertilization under straw returning on yield of new wheat variety Rumai 1.Four tillage modes with straw returning and three nitro-gen rates were designed.The results showed that deep tillage under straw returning combined with 20 kg per 666.7m2 of nitrogen was the best for increasing the yield of Rumai 1,while the mode of two -year rotary tillage +one -year deep tillage after straw returning was more economic.
