生物质炭和果胶对再生水灌溉下玉米生长及养分、重金属迁移的影响
Shuitu Baochi Xuebao, 2017 利用根箱试验方法比较了生物质炭和果胶对再生水灌溉下土壤—植物系统养分和重金属迁移特征的影响及差异性。结果表明,再生水灌溉不利于植物的生长,果胶和生物质炭两个处理相比,虽然植株生长无显著差异,但果胶处理植株的生长状况优于生物质炭处理;再生水灌溉时,果胶处理地上部生物量比对照增加了59.32%。与蒸馏水灌溉相比,再生水灌溉增加了根际土壤pH;灌溉水源相同时,果胶处理根际土壤pH略低于生物质炭处理。生物质炭和果胶都增加了土壤养分的含量,果胶对土壤碱解氮、有效磷和有机质的增加效果优于生物质炭 ...刘, 崔二苹, 李中阳, 杜臻杰, 高, 樊向阳 +5 moredoaj Defoliation and fertilisation differentially moderate root trait effects on soil abiotic and biotic properties
Journal of Ecology, Volume 111, Issue 12, Page 2733-2749, December 2023., 2023 Our results indicate that defoliation and fertilisation, two common grassland perturbations, have contrasting impacts on root traits of grassland plant species, with direct and indirect short‐term consequences for a wide range of soil abiotic and biotic properties that underpin ecosystem functioning.Yan Liu, Irene Cordero, Richard D.

Methods in Ecology and Evolution, Volume 14, Issue 6, Page 1443-1456, June 2023., 2023 Abstract Successful use of stable isotopes (δ2H and δ18O) in ecohydrological studies relies on the accurate extraction of unfractionated water from different types of soil samples. Cryogenic vacuum distillation (CVD) is a common laboratory‐based technique used for soil water extraction; however, the reliability of this technique in reflecting soil ...Bin Yang, Gbadamassi G. O.

工程设计与施工, 2020 生物质炭具有较强的吸附性特点,能针对土壤当中的无机污染物进行有效处理,从而促进土壤环境质量的提升。生物质炭在表面电荷、含氧官能团和孔隙结构方面具有一定的特殊性,因此也决定了其吸附能力的强大。同时,能降低成本投入,保障污染处理的高效化。明确生物质炭对土壤无机污染物迁移行为的影响特点,有助于生物质炭价值的充分发挥,为实践工作提供依据。论文针对生物质炭的特性进行介绍,分析生物质炭对土壤无机污染物迁移行为的影响机制,探索生物质炭在土壤无机污染物治理中的应用价值。代永 博semanticscholar +1 more sourceThe handbook for standardized field and laboratory measurements in terrestrial climate change experiments and observational studies (ClimEx)
