摘要
利用金山围填海项目围堤、吹填之际,在模拟盐碱土上整体覆土。经过对5种处理的pH、电导率(EC)、全盐量、有机质这些指标的统计分析后,提出土壤与有机改良材料的最低体积比为4∶1;建议设置隔盐设施条件下的覆土高度,大规格乔木2.0 m,一般乔木1.5 m,灌木1.0 m,地被和草坪0.6~0.8 m;指出有机材料优先选择酸性,并持续投入,保证用量。
During the embankment and reclamation engineering for Jinshan reclamation project,the simulated saline-alkali soil was covered with the soil for planting.After statistical analysis of pH,EC,total salt content and organic matter of the covering soil in 5 kinds of processing,the paper proposed that the minimum volume ratio of soil to organic modified materials was 4∶1.It was suggested that the covering height under the condition of salt separation facilities should be 2.0 m for large size trees,1.5 m for general trees,1.0 m for shrubs,and 0.6-0.8 m for ground cover and lawn.It was pointed out that organic materials should be preferentially acidic,and should be continuously input to ensure its amount in the soil.
