摘要
土壤污染导致土壤的物理、化学和生物学性质发生改变,降低农作物的产量和质量,并最终危害人体健康。腐植酸具有良好的生理活性和吸收、络合、交换等功能,能较好的改良土壤。本文介绍了腐植酸的特性,腐植酸对重金属的污染的防治、对农药的增效及污染防治、对酸性土壤性能的影响及节水抗旱作用几方面内容,并对腐植酸的应用前景进行了展望。
Soil pollution could change the physical, chemical and biological properties of soil, reduce the yield and quality of crop, and then do harm to human health. Humie acid can improve soil quality due to its physiological activity, absorption, complexation, exchange, and other functions. The prevention and treatment of heavy metal pollution, efficiency improvement and pollution prevention of pesticides, influence on the performance of acidic soil, and water - saving characteristics of humic acid were shown in the paoer. Also the develooment trends and aoolieation nrosnect of humic acid was indicnted.
