中文摘要
我国南方日趋严重的农田土壤酸化不仅导致农作物大幅度减产甚至绝收，而且促进重金属等有害物质在农产品中吸收累积，威胁国家粮食安全和民众健康。但因酸性土壤分布详情不清，作物酸害阈值不明，土壤酸化预测的研究不足，酸化防治技术严重缺乏，红壤酸化没有得到有效控制。采取有效措施改良酸化农田土壤、遏制土壤的持续酸化，将热带和亚热带地区的土壤酸度维持在较低水平，对我国农业可持续发展和乡村振兴战略的实施具有重要意义。
英文摘要
Soil acidification of croplands in South of China became serious in recent decades. This not only led to the reduction in crop yields, but also enhanced uptake and accumulation of heavy metals in agricultural products, which threatened peoples' health. The main scientific issues for soil acidification control are:(1) the distribution of acidic soils in detail and the critical pH and soil Al concentration to harm various crops are not clear; (2) the prediction of soil acidification trends needs to be investigated; (3) the controlling strategies for soil acidification need to be developed. It is significant for sustainable agriculture and revitalizing rural economy to develop various technologies to ameliorate soil acidity and inhibit soil acidification and thus maintain soil acidity at low level.
