摘要
世界钾肥消费近年来呈增长之势,但国际市场已成高度垄断局面。我国钾肥自给率仅30%。当前,加拿大萨斯卡彻温南部及老挝万象钾矿勘探及开发均有较好进展。为缓解我国钾盐短缺状况,需要从加大找钾工作投入;加强找矿基础地质及预测研究;加强海水和苦卤提钾技术研究;开展不溶性钾资源的开发和利用;改善施肥对策、科学施肥、重视农家肥的作用等方面入手。
In recent years, expenses in kalium fertilizer of the world is growing, but in the international market it was highly monopolised. The domestic content ratio is only 30%. The exploration and development of kalium minerals at the south of Saskatchewan in Canada and Vientiane in laos are well currently. In order to resolve the lack of sylvite in our country, we should increase the work at prospecting sylvite, the basic geology and the studies on prediction, refining the kalium with seawater and acrid bittern, as well as develop the infusibility kalium resource and fertilization measures scientifically.
