摘要
目前,我国是世界上土壤盐渍化问题较为严重的国家之一,主要分布在东北、华北、西南、西北以及沿海地区.盐渍化土壤存在养分不足、盐度高和生产力低等主要缺点,可通过添加功能性肥料进行改良.文章在总结了盐渍化土壤现状和危害的基础上,综述了目前改良措施、功能性肥料的特性和用于改善盐渍化土壤的机理及影响,对未来改良盐渍化土壤的技术进行了展望.为功能性肥料的进一步开发及在盐渍化土壤治理中的应用研究提供参考,对选择经济、合理和高效的治理措施改善盐渍土壤质量和提高作物的产量具有借鉴意义.
Abstract
At present,China is one of the countries with serious soil salinization problems in the world,mainly distributed in Northeast China,North China,Southwest China,Northwest China and coastal areas.Salinized soil has the main disad-vantages of insufficient nutrients,high salinity and low productivity,which can be improved by adding functional fertilizers.In this paper,on the basis of summarizing the current situation and hazards of salinized soil,the current improvement meas-ures,the characteristics of functional fertilizers,the mechanism and impact of improving salinized soils are reviewed,and the future technologies for improving salinized soils are prospected.This paper provides a reference for the further develop-ment of functional fertilizers and their application in salinized soil treatment,and has reference significance for selecting e-conomical,reasonable and efficient treatment measures to improve the quality of saline soil and increase crop yield.
