Twoyears field experiment was carried out to explore the effect of biochar on soil fertility，crop nutrient uptake and spring wheat yield under drip irrigation condition.Results showed that biochar treatments significantly increased soil fertility and crop nutrient untake content comparing with CK treatment.Biochar had positive effects on yield and components of spring wheat.NP+B6 treatment significantly increased soil organic matter，soil total nitrogen，soil available potassium，phosphorus absorption of spring wheat comparing with NP treatment.Soil total N，available potassium and nutrient uptake of wheat were significantly（P<0.05）increased under NP+B6 treatment comparing with NP+M6 treatment.
