【目的】探明生物炭、有机肥与化肥配施对春玉米养分利用及产量的影响,为生物炭农业应用和玉米高效生产提供参考依据。【方法】在湖南省浏阳市开展田间小区长期定位试验基地,设置不施肥(T1)、单施化肥(T2)、化肥与生物炭配施(T3)、化肥与有机肥配施(T4)、化肥+生物炭+有机肥混施(T5)5个处理,春玉米生育期氮、磷和钾总养分施用量分别为240、120和150 kg/ha,对春玉米的地上部氮磷钾累积量、肥料利用率、地上部鲜重及籽粒产量等指标进行测试分析。【结果】施肥有助于春玉米对养分的吸收利用及增产。与T2处理相比,T3、T4和T5处理均不同程度地增加春玉米地上部氮磷钾累积量、肥料利用率、穗鲜重、茎叶...
