土壤酸化及酸性土壤改良技术研究进展

Research Progress in Soil Acidification and Acid Soil Improvement Technology

近年来,土壤酸化越来越严重,其作为土壤退化的重要指标之一,已严重影响着作物的生长。综述了自然与人为情况的两大酸化原因以及酸化对土壤质量、作物生长及微生物生命活动等的危害。最后从酸雨沉降的控制、土壤改良剂的使用、生物及农业措施等方面提出对酸性土壤的改良与修复方法。

In recent years, soil acidification has become more and more serious, and it is one of the important indicators of soildegradation, which has seriously affected the growth of crops. In this paper, the two main acidification causes of natural and man-madeconditions and the harm of acidification on soil quality, crop growth and microbial life activity were reviewed.In the end, the methods ofimprovement and restoration of acid soil were put forward from the control of acid rain deposition, the use of soil amendments, biologicaland agricultural measures.
