Phosphate fertilizer: From a blank to the world's first

This year marks the 100th anniversary of the founding of the Communist Party of China, the 63rd year of the development of the phosphate fertilizer industry, and the opening year of the "14th Five-Year Plan"
.

For the phosphate fertilizer industry, this year is a new round of industrial reform

During the period of the first five-year plan, China's phosphate fertilizers had initial development
.

However, based on the actual situation at that time, China chose to start with low-concentration phosphate fertilizers and mainly produce phosphate rock powder.

In order to meet the agricultural demand for phosphate fertilizer, the Nanjing Phosphate Fertilizer Plant was completed and put into operation in 1958.
Since then, China's phosphate fertilizer industry has officially set sail
.

During this period, China's phosphate fertilizer industry has formed a development pattern that combines large, medium and small enterprises, and at the same time, there has been a significant increase in production technology and product output

In the 1960s, the development direction of phosphate fertilizers in the world turned to large-scale, high-concentration, compound, multi-specification, and multi-variety specialty fertilizers
.

By the end of the 1970s, the output of high-concentration phosphate compound fertilizers in developed countries accounted for 70% of the total phosphate fertilizer output, while China was basically in a blank at that time

It was not until 1978 that the former Ministry of Chemical Industry organized a delegation to study and inspect developed countries in Europe and the United States, and determined that China's phosphate fertilizer industry should implement the development policy of "simultaneous development of independent development and introduction of technology"
.

At this time, China's phosphate fertilizer industry began to adjust its product structure

Since 1980, China has successively started to build 15 phosphate fertilizer plants, 3 phosphate mines, 1 pyrite mine, and 1 potash mine, and successively introduced technology and equipment from abroad.
These projects were completed and put into operation after 1990
.

Subsequently, China has done a lot of work in digestion, absorption, innovation and localization.

Since then, China's phosphate fertilizer industry has started a rapid development model and prospered all the way, which can be seen from the number of phosphate fertilizer companies in China
.

Data show that in 1980, there were 739 phosphate fertilizer enterprises nationwide, with a total industrial output value of 1.

Not only that, China's phosphate fertilizer output has also become the world's first
.

According to statistics, China's phosphate fertilizer output in 1980 was 2.

Since the "13th Five-Year Plan", China's phosphate fertilizer industry has been guided by supply-side structural reforms, through optimization and adjustments, to comprehensively promote transformation and upgrading
.
Nowadays, China's phosphate fertilizer industry pays more attention to green environmental protection
.
With the continuous improvement of waste gas treatment technology in recent years, purification equipment has gradually replaced low-efficiency absorption equipment with high-efficiency and energy-saving equipment, and the pollutants discharged into the environment have been reduced accordingly
.
At present, all domestic large and medium-sized phosphate fertilizer companies and some small phosphate fertilizer companies have built sewage treatment engineering installations, with a relatively high coverage of treatment facilities and good pollutant removal effects
.

Not only that, the comprehensive utilization of phosphogypsum, a by-product of the phosphate fertilizer industry, has also achieved world-renowned achievements.
The utilization channels have gradually expanded, and the utilization level and utilization rate have increased year by year
.
At the same time, the comprehensive utilization of phosphogypsum, such as cement retarder, construction gypsum powder, gypsum block, gypsum mold box, etc.
, has continuously expanded the production capacity, and the start-up rate has continued to increase; the operation of the chemical treatment of phosphogypsum and the development of new technologies New progress has been made; the research and development of harmless pretreatment technology and preparation of high-strength gypsum technology has laid a solid foundation for the promotion of resource utilization of phosphogypsum
.

　　During the "14th Five-Year Plan" period, China's phosphate fertilizer industry will strive to achieve the overall goals of structural adjustment, quality and efficiency improvement, innovative development and green development, enhance overall competitiveness, make the industry better meet the needs of modern agricultural development, and ensure national food security
