保护地土壤次生盐渍化的研究进展

Progress in the study on soil salinization of protected farmland

保护地土壤次生盐渍化防治是设施栽培中普遍存在的技术难题。本文根据近年来国内外有关研究成果 ,综述了保护地土壤次生盐渍化诱发的作物生长发育营养障碍因子及土壤次生盐渍化发生机理 ,从离子组成变化的角度阐述了保护地次生盐渍土的基本特性 ,并有针对性地提出了保护地土壤次生盐渍化的防治途径和措施。

Prevention and cure are very difficult by agritechnology for soil salinization of sheltered farmland. On the basis of research achievements in recent 10 years, the nutriental barrier of crop growth and development led by soil salinization and the mechanisms of soil salinization were reviewed, the characteristic of salinized soil in sheltered ground was discussed based on the composition variation of ions, and the keys to prevent soil salinization of sheltered ground was put forward.
