摘  要：
要:盐碱化土壤改良和开发利用是世界研究热点。从土壤结构分析,结合土壤团粒结构及其水盐运移规律,揭示土壤盐碱化成因主要是土壤中粒径≥0.25 mm团粒结构减少,毛细管水增加,促进易溶性盐类向地面方向聚集,对植物形成"生理干旱"。利用土壤团粒结构-水-盐一体化调控改良土壤,是盐碱化土壤从源头治理的方向;依次从土壤团粒结构-水-盐一体化的思路分析盐碱地的物理改良、化学改良、生物改良、水利工程改良、腐植酸改良的进展,提出盐碱地腐植酸绿色可持续改良技术方案。

摘  要：
The improvement and exploitation of saline-alkali soil is a hotspot in the world.In this paper,the saline-alkali soil formation was discussed based on the analysis of soil granular structure,migration law of water and salt in soil.The saline-alkali soil formation was due to the decrease of granular structure particle with size≥0.25 mm,subsequently caused the increase of capillary water and promoted aggragation of easy soluble salts in the direction of the ground that forming"physiological drought"to the plant.The direction of soil salinization in source governance is to control the integration soil granular structure-water-salt.The salinealkali humic acid green sustainable improvement technical solutions depended on the progress in saline-alkali improvement technologies including physical,chemical,biological,water conservancy project and humic acid improvement that were analyzed from the idea of soil granular structure-water-salt integration.
