With the gradual recovery of the domestic economy and factors affected by natural disasters, the rise in grain prices will increase farmers’ enthusiasm for growing grain and thus use fertilizers. The demand will increase. In addition, the domestic February to May and September to October are peak seasons for fertilizer use. Internationally, according to different circumstances, the fertilizer season is different. According to these various reasons, the demand for phosphate fertilizer has certain rules to follow. The relevant data shows that at present, the domestic demand for phosphate fertilizer production is about 70%, while the export volume is about 30%. However, the situation in Yunnan-Guizhou area is slightly different, and the export volume is larger, accounting for the total export volume of the country. About 50%, mainly because of the high degree of industrial concentration in these areas, production capacity. The demand of the world*s mainly comes from the increase in production of phosphate fertilizers for agriculture and non-fertilizer industry* such as non-ferrous metal beneficiation. At present, fertilizer use* accounts for 54% of total demand, and metal beneficiation* accounts for 46%. Since 2008, affected by the financial crisis, both the phosphate fertilizer industry and the non-fertilizer industry have seen a decline in the demand for **, but the consumption of both the fertilizer industry and the non-fertilizer industry will resume growth in 2010 and the demand will reach 70 million tons. Above, it exceeded the 2007 level. He said that in the future, the growth of demand will come from developing countries, especially in East Asia. It is predicted that the growth of Phosphatic fertilizer in East Asia in 2011 will account for 75% of the world's growth. In addition, the demand of India and Pakistan in South Asia will also increase. bigger. In summary, the demand for phosphate fertilizers has increased, and the demand for ** has fallen. The two sides have contrasted, and the demand for them has increased.
