秸秆和生物炭对不同含水量下土壤性质和番茄幼苗生长的影响
发布时间:2020-12-20 17:17
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NO3--N,而NH4+-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...
