秸秆和生物炭的应用有助于改善不同水分含量下土壤质量,土壤生化性质,以及促进植物生长。本研究的目的是探讨不同水分条件下秸秆和生物炭对番茄幼苗生长及土壤质量的影响。通过温室盆栽试验评估不同水分条件下秸秆和生物炭的作用。总共有14种处理,三种生物碳水平(1%,3%和6%),三种秸秆水平(1%,3%和6%)和两种水分含量(M1,40%的饱和含水量)和(M2,70%的饱和含水量),对照无任何添加物。结果表明,在M1和M2两种含水条件下,小麦秸秆和生物炭对土壤pH值无显著影响,增加了土壤有机碳(SOC)含量。在M1含水量下,添加6%生物炭,使得全氮(TN)增加了45%。秸秆和生物炭添加,显着增加了土壤有效磷和钾含量。与秸秆和对照处理相比,生物炭处理显着降低了土壤NO-N,而NH-N含量,但在两种水分水平下无显着差异。对于M2处理,与1%秸秆添加相比,1%生物炭显着增加土壤脲酶活性(15%),并降低脱氢酶和β葡糖苷酶的活性(67%和56%)。生物炭提高了枝条和根干重,以及生物量和叶绿素a含量,而降低了叶绿素b含量。在添加秸秆处理中,植物抗氧化酶和丙二醛(MDA)含量显着增加;然而,在生物炭处理中呈现下降趋势。目前的研究结果表明,在M2水分条件下,半干旱地区施用6%的生物质炭和1%的秸秆将是一种合理的管理措施,能显著改善番茄幼苗的土壤理化性质和生理特性。

土壤水力学性质和功能的变化是评价长期施肥是否维持土壤可持续健康发展的重要方面。该研究通过采取"国家黄土肥力与肥料效益监测基地"的表层原状土壤,分析测定了撂荒(LH)、休闲(XX)、不施肥(CK)、单施氮肥(N)、氮磷钾肥(NPK)和有机肥与氮磷钾肥配施(MNPK)6个处理的土壤水分特征曲线、饱和导水率和紧实度等指标,评价了长期定位施肥对土壤基本物理性质和水力学性质的影响。结果表明:1)与CK、N和NPK处理相比,MNPK处理显著提高了土壤有机碳、饱和导水率和孔隙度,而降低了土壤容重和紧实度(P9μm大孔隙范围内,其次是<0.2μm小孔隙范围,0.2～9μm之间的中孔隙分布较少。综上,MNPK有助于改善土壤结构,提高土壤持水性,降低土壤容重和紧实度,有助于作物生长和高产,是关中地区较为适宜的施肥措施。
