Abstract	S156.4; [目的]改善滩涂区土壤理化性质,降低耕层盐分,提高土壤肥力,提高滨海滩涂区盐渍土生产力,实现该区农业可持续发展.[方法]通过盆栽试验,设置普通生物炭(A)和酸改性生物炭(B)及其不同施量(2％、4％、8％)共6个处理,不添加生物炭作为对照(CK),研究了生物炭及其施量对土壤理化特性的影响.[结果]不同施量的生物炭均显著降低了土壤体积质量,增大了土壤孔隙度,有效提高了土壤的持水性能,且施量越高正效应越强,普通生物炭改善效果略优于酸改性生物炭.适量添加生物炭可增强土壤盐分淋洗,提高脱盐率,调节土壤pH值,添加2％酸改性生物炭处理(B2)土壤脱盐率最高,为72.05％,但高施量普通生物炭(A8)不利于土壤脱盐.添加生物炭显著提高了土壤有机质(SOM)和硝态氮量,试验组内以A8、B4处理有机质和硝态氮量较高.[结论]普通生物炭及酸改性生物炭均能有效降低滩涂区土壤含盐量并提高土壤肥力,综合考虑土壤水、盐、肥状况,适量的酸改性生物炭(4％)方案比较适宜研究区盐渍土改良利用.
