农业土壤盐碱化修复治理研究进展
|
Abstract:
农业土壤的盐碱化已经成为影响农业可持续发展的重要因素之一，本文综述了农业土壤盐碱化的主要因素，并为延缓农业土壤盐碱化的关键的治理技术进行简介。许多修复技术已经被应用于降低土壤盐度和碱度，包括上覆下隔阻隔控盐碱、暗管排盐脱盐碱、土壤改良增强脱盐碱、耕地土壤破粘降盐碱、灌溉调控、生物修复、酸碱平衡调控、土壤堆肥抑制盐碱、作物抗盐碱栽培等农田土壤盐碱化修复治理技术。农业土壤盐碱化修复需要根据土壤条件对其进行多技术综合应用，才能达到成本可控、绿色环保的修复治理需求。
The salinization of agricultural soil has become one of the most obstructive factors for the sus-tainable development of agriculture. This paper reviews the main factors of the salinization of ag-ricultural soil, and introduces the key technologies to remediate the salinization of agricultural soil. Many remediation technologies have been applied to reduce soil salinity and alkalinity, including over covering and underlying barrier, hidden pipe salt elimination, soil improvement, soil viscosity breaking, irrigation regulation, biological remediation, acid-base balance regulation, soil composting, crop saline-alkali resistant cultivation. The remediation of agricultural soil with sali-nization-alkaline need the comprehensive application of multiple technologies according to soil conditions for the requirements of cost controllable, green and environmental protection.
