盐碱土与非盐碱土团聚体差异、改良影响及启示

Shuitu Baochi Xuebao
目的团聚体是土壤肥力的重要指标，其稳定性直接影响土壤物理、化学和生物特性。在盐碱化条件下，团聚体受到土壤高盐分或强碱性的影响，易导致土壤结构退化和功能降低，严重限制农业生产。旨在总结盐碱土与非盐碱土团聚体的差异，分析盐碱化条件下影响团聚体形成和稳定性的因素。方法探讨改善盐碱土团聚体结构的方法与策略及非盐碱土团聚体研究对盐碱土的启示。结果综合分析发现，盐碱环境破坏土壤结构，降低微生物多样性和活性，导致大团聚体数量减少，微团聚体比例上升，团聚体稳定性较差。非盐碱土大团聚体和微团聚体数量均较高，且分布层次分明，

麻砂泥田与鳝泥田土壤团聚体分布特征及其对镉吸附与形态的影响

Shuitu Baochi Xuebao
目的为揭示土壤各粒级团聚体组分理化性质及其对镉（Cd）赋存形态的影响机制，研究典型水稻土团聚体分布特征及不同粒径团聚体对Cd环境行为的影响。方法选取Cd污染水稻土麻砂泥田（花岗岩发育）与鳝泥田（板页岩发育），通过湿筛法将土壤团聚体分为4个粒级：大团聚体（2~8 mm）、中间团聚体（0.25~2 mm）、微团聚体（0.053~0.25 mm）和粉黏粒（<0.053 mm），分析不同粒径团聚体去除有机质与游离态氧化铁对Cd的吸附作用。结果2种土壤均以大团聚体为主，鳝泥田团聚体结构较麻砂泥田稳定 ...
