摘要
中国钾肥消费逐年增加，进口依赖度已高达达70％，国际钾肥价格的过快增长给国内钾肥市场带来了极大的影响。通过分析资源、工业生产、农田需求3个环节，提出了我国钾肥发展的战略方向。我国现有钾资源可利用年度仅66年左右，受自然条件限制钾肥产量增长困难，需要根据钾肥需求合理调控资源利用和产业发展。通过技术优化和合理调配，我国近期农田钾肥需求可以调控到400万～550万tK2O。通过调控农田需求，加强化学钾肥、土壤钾和有机钾资源的循环利用和补偿，钾肥自给率在2010年可达55％，2015年可达70％，国际钾肥市场的冲击将逐步降低。但从长远来说，我国仍要加强资源勘探，加强国内、海外投资和国外钾资源三者之间的调配。
Po ＇rash fertilizer consumption has increased siguificandy in China in the past several years, but 70% of potash fertilizer in China relays on the international market. Its rapid increasing price in international market has brought very big effects on China＇s market. An integrated analysis on the resource, fertilizer industry and agriculture/demmld is made and the developing strategy for China＇ potash fertilizer industry is put forward. The results present that the explored potash mines in China would be used up for 66 years, and the potash fertilizer production cannot be enlarged very fast in next few years because of the limitation of natural resources. This makes China have to regulate the utilization of resources and industrial development of potash fertilizer. By way of technological optimization and reasonable arrangement the demand for potash fertilizer in China can be controlled between 4 million to 5.5 million tons of K2O before 2015. Therefore the domestic fertilizer production can reach 55% in 2010 and 70% in 2015 by controlling farmland demand and improving reuse and compensation of K in soil, inorganic and organic fertilizers. The impact from the international market will be reduced gradually, but in a long period of time China must strengthen the exploration of potash resource, and arrange well the domestic, overseas investment and resources.
