脱硫石膏改良盐碱土的研究进展

摘要

随着人口资源矛盾的加剧,盐碱地开发、改良成为普遍关注问题.利用工业副产物脱硫石膏,可以有效改良盐碱地,提高作物产量.综述了石膏改良盐碱土的原理、研究方法以及影响石膏改良盐碱土的因素,着重讨论了石膏施用方法、石膏施用量以及灌水量和灌水次数对石膏改良碱土的影响,并对石膏改良盐碱土研究工作的思路进行了初步的探讨和展望,以期为石膏改良盐碱土提供借鉴.%With the population-resource conflicts strengthening,saline-alkali soil improvement has become a common concerned problem.Utilization of industrial by-product gypsum can be effective in improving saline-alkali soil and increasing crop yield.Principle,gypsum saline-alkali soil improvement methods and influence factors of gypsum saline-alkali soil improvement were reviewed.Emphatically,the application of gypsum,gypsum dosage and method of irrigation amount and frequency effects on gypsum improving alkaline soil were discussed,as well as the gypsum saline-alkali soil improvement research ideas,in order to provide reference for gypsum improvement of saline-alkali soil.
