我国国产钾肥目前每年只有 2 6万ｔ,仅占需求量的 5% ,远远不能满足需要。我国是一个钾盐资源匮乏的国家。专家认为 ,中国土壤缺钾问题要得到根本解决 ,2 1世纪中国钾肥出路有三条 :国内生产、国外风险勘查开发和进口。国内生产主要是加快开发利用青海柴达木盆地盐湖钾盐资源的 China’s domestic potash fertilizer currently only has 26,000 tons per year, which only accounts for 5% of the demand, far from meeting the needs. China is a country with a shortage of potash resources. Experts believe that the problem of potassium deficiency in soil in China needs to be fundamentally solved. There are three ways of potash fertilizer in China in the 21st century: domestic production, foreign risk exploration and development, and import. Domestic production is mainly to speed up the development and utilization of salt lake potassium resources in Qaidam Basin, Qinghai Province
