| 摘 要： | 为探讨生物有机肥对不同类型盐渍土壤(设施次生盐渍土、滨海盐渍土)水盐动态和作物产量的影响,采用盆栽试验方法研究不同施肥(不施肥、化肥、生物有机肥、生物有机肥+化肥(比例为1∶1))处理对盐渍土土壤含水率、电导率、盐分离子组成变化和番茄产量、水分利用效率的影响。结果表明:(a)单施生物有机肥处理和生物有机肥+化肥处理均可以提高土壤含水率;(b)单施生物有机肥处理的土壤电导率最低,其次为生物有机肥+化肥处理;(c)对于设施次生盐渍土,与化肥处理相比,单施生物有机肥处理和生物有机肥+化肥处理的土壤盐分离子总量分别降低了23.63%和15.60%;(d)对于滨海盐渍土,与化肥处理相比,单施生物有机肥处理和生物有机肥+化肥处理的土壤盐分离子总量分别降低了22.34%和10.32%;(e)番茄收获后,设施次生盐渍土各处理的NO_3~-和SO_4~(2-)在土壤盐分中的占比降低,滨海盐渍土各处理的Na~+、K~+和Cl~-占比降低;(f)单施生物有机肥处理最有利于土壤微生物的增加,其次是生物有机肥+化肥处理;设施次生盐渍土中生物有机肥+化肥处理的番茄产量最高,比单施生物有机肥处理增产165.5%;(g)施用生物有机肥可以提高设施次生盐渍土的作物产量和灌溉水利用效率,而单施化肥则可能会造成作物绝产;(h)施用化肥虽然提高滨海盐渍土的作物产量,但施用生物有机肥处理的灌溉水利用效率相对较高。
