摘要
我国是钾资源匮乏的国家,一半以上的钾肥依赖进口。随着我国察尔汗和罗布泊地区储量有限的可溶性卤水钾资源的大量开发,钾资源供应紧张形势将日趋严重。重点介绍了我国在难溶性钾资源、海水钾资源高效、低耗、低成本开发利用技术方面取得的重要进展,并就未来发展趋势提出展望。
China is a country deficient in potassium resources, more than half of its potash fertilizer is relied on import. With mass exploitation of soluble potassium brine resources, which limit reserved in the Qarhan and Lopnor regions, the situation of tight supply of potassium resources will increasingly tighter. The important progress in use and development of indissoluble potassium resources and potassium resource in seawater with high efficient, low energy consumption and low cost is presented with the emphasis and future development trend is predicted.
