为实现南荻秸秆炭化利用，缓解洞庭湖区因其处置不当造成的环境压力，评估南荻生物炭农用增效潜力。选用南方第四纪红土母质发育的红黄泥和花岗岩母质发育的麻砂泥水稻土，设置6个不同用量的南荻秸秆生物炭处理（质量比0、1%、2%、4%、6%和8%；0～20 cm土层），采用水稻盆栽试验，研究南荻秸秆生物炭不同施用量对两种类型土壤下水稻养分利用特征的影响。结果表明，南荻秸秆生物炭不同施用量和土壤类型对水稻各器官及地上部干物质累积、养分吸收均有影响。与不添加生物炭相比，添加1%～8%生物炭处理下的红黄泥和麻砂泥水稻土地上部干物质量分别提高了0.6%～18.6%和15.6%～42.4%；添加4%生物炭的麻...
