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.%为了解生物炭对滴灌春小麦产量及土壤肥力的影响,通过2年田间试验对灰漠土土壤和春小麦养分及产量等进行了研究.结果表明:与CK相比,施用生物炭显著(P<0.05)增加了土壤肥力,并显著(P<0.05)增加春小麦对N、P和K的吸收,还对春小麦产量及构成具有积极的促进作用.与NP处理相比,NP+B6处理显著(P<0.05)增加了土壤有机质、 全氮和速效钾含量以及植株吸磷量.与NP+M6处理相比,NP+B6处理显著(P<0.05)增加了土壤全氮、 速效钾和植株养分吸收量.
