In recent years, due to factors such as low domestic crop prosperity and environmental protection production restrictions, my country's phosphate fertilizer production capacity and output have begun to shrink. According to the data of China Phosphate and Compound Fertilizer Association, the total output of phosphate fertilizer in China in 2018 was 16.963 million tons, down 0.9% year-on-year; of which high-concentration phosphate fertilizer was 16.101 million tons, up 0.2% year-on-year, and low-concentration phosphate fertilizer was 863,000 tons, down 18.1% year-on-year. The output of monoammonium phosphate and diammonium phosphate in 2018 was 15.092 million tons and 16.238 million tons respectively, an increase of 10.18% and 0.61% year-on-year respectively.

In the future, the environmental protection pressure of the chemical industry, including phosphate fertilizers, will exist for a long time, and the supply of phosphate fertilizers in my country will continue to shrink.

In 2018, the output of the top 5 provinces in domestic phosphate fertilizer production accounted for 85.7% of the country's total phosphate fertilizer output, and the top 10 enterprises accounted for more than 63% of the country's total phosphate fertilizer output. With the continuous development and growth of domestic phosphate fertilizer production enterprises, especially in recent years, mergers and acquisitions have been strengthened, the number of mergers and acquisitions has increased, the number of basic fertilizer enterprises has decreased, and large-scale, comprehensive, cross-industry and cross-regional enterprise groups have increased, and my country's phosphate fertilizer industry is concentrated. greatly increased.
