Discussion of Saline-alkali Soil Improvement Technology and Humic Acid Applied Technology

Tian Yiliang;Liu Yansheng;Zhang Haibing;Institute of Technology,China University of Petroleum-Beijing at Karamay;  
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.
