烟气脱硫石膏改良新疆盐碱化土壤应用在棉花种植的优势分析与前景展望

Advantage Analysis and Prospect of Application of Flue Gas Desulfurization Gypsum to Improve Saline Alkali Soil in Cotton Planting in Xinjiang

本文针对新疆维吾尔自治区(下文简称新疆)盐碱土壤高发对棉花种植造成严重影响的现状,通过查阅烟气脱硫石膏改良盐碱化土壤的相关研究资料,对比多种土壤盐碱化改良措施的经济效益,结合烟气脱硫石膏改善土壤的机理及对不同盐度、碱度和各类离子浓度对棉花生长的影响,从烟气脱硫石膏改良盐碱化土壤特性和施用方式两方面论证烟气脱硫石膏改良盐碱化土壤应用于棉花种植的适用性,探讨目前烟气脱硫石膏改良盐碱化土壤在新疆棉花种植应用方面存在的问题。

Based on the current situation of high incidence of saline-alkali soil in Xinjiang,which has a considerable impact on cotton planting;this paper,compared the economic benefits of various soil salinization-improvement measures by consulting relevant literature on using flue gas desulfurization gypsum to improve the salinization soil;and further,demonstrated the applicability of flue gas desulfurization gypsum-facilitated improvement of saline-alkaline soil characteristics and application methods to cotton planting,in combination with the mechanism of soil improvement by flue gas desulfurization gypsum and the effects of different salinity,alkalinity,and ion concentrations on cotton growth.This paper demonstrates the applicability of the application of flue gas desulfurization gypsum to the improvement of saline alkali soil in cotton planting from two aspects of the characteristics and application methods of flue gas desulfurization gypsum to improve saline alkali soil,and discusses the problems existing in the application of flue gas desulfurization gypsum to the improvement of saline alkali soil in cotton planting in Xinjiang.
