摘要
盐碱土壤水溶性全盐含量高、有机质含量低、结构不良等缺点严重降低蔬菜产量。设施蔬菜通过膜下滴灌可以显著降低表层土壤含盐量,形成淡化脱盐土层,提高灌溉水分的利用率。施用盐碱土壤调理剂在一定程度上能够改善土壤理化性状,改变土壤盐离子组成,降低土壤含盐量。施用有机物料能够增加盐碱土壤有机质,促进团粒结构形成,降低土壤pH值,提高盐碱地的养分含量,减缓蔬菜盐渍胁迫。
High salinity,low organic matter content and poor soil structure severely limited vegetable production in saline-alkali area.In facility vegetable production,drip irrigation could significantly reduce salt content in topsoil and improve water and nutrition utilization rate though forming desalinized soil layer.Application of conditioner in saline-alkali soil could partly improve soil physicochemical properties,change the composition of salt ions,and decrease salt content.Application of organic manure could alleviate salt stress by increasing soil organic matter content,promoting the formation of soil aggregate structure,decreasing pH value and increasing nutrients in saline-alkali soil,so relieved the salt stress to vegetables.
