生物质炭与有机肥对盐碱土壤特性的影响
发布时间：2021-07-20 14:43
土壤盐碱化是当今世界土壤退化问题最严重的问题之一。尽管土壤盐碱化程度在全世界范围内都有所增加,但是单施或混合施用有机肥被认为是具有潜力的改良土壤盐碱化的措施。盐碱土土壤生产力低,因此改良土壤盐碱化以提高作物产量迫在眉睫。有学者建议向盐碱土壤施用有机改良剂（生物炭+有机肥）来提高盐碱土的土壤肥力和改善理化性质。本试验采用560℃和800℃高温产生的生物炭混合有机肥（猪粪）,来探究生物质炭单施、有机肥单施和生物炭有机肥混合施用对盐碱土改良的适用性和持久性。本试验处理包括:不施用改良剂（T0）,单施生物炭15 t·ha-1（T1）,单施生物炭30 t·ha-1（T2）,单施猪粪15 t·ha-1（T3）,单施猪粪30 t·ha-1（T4）,混合施用生物炭猪粪共15 t·ha-1（T5）,混合施用生物炭猪粪共30 t·ha-1（T6）,以上每种处理施加在两个土层中（0-15和15-30 cm）。土壤有效养分含量连续测定两...
