The hottest national slow and controlled release f

The national slow and controlled release fertilizer engineering technology research center was established

the national slow and controlled release fertilizer engineering technology research center recently settled in Shandong Jinzhengda group. This is the only national scientific research platform in China's slow-release and controlled-release fertilizer industry. The establishment of the center marks that China's fertilizer industry has entered a new era of development, and will help promote the R & D, promotion and application of slow-release and controlled-release fertilizer industry to a fast track

the so-called slow and controlled release fertilizer, It is a mode of nutrient release through various control mechanisms. According to the design, users are welcome to visit our factory for guidance (including release rate and continuous effective release, "our high gloss materials create an elegant appearance similar to glass") It is synchronized with the absorption of nutrients by crops - that is, fertilizer consistent with the law of nutrient absorption by crops. Slow and controlled release fertilizer is known as "new environmental protection fertilizer in the 21st century" because of its characteristics of saving time and labor, increasing production and efficiency, energy conservation and environmental protection

statistics show that from 1996 to 2008, the use of chemical fertilizer in China increased by 36.9%, but the total grain output increased by only 4.7%, and the production input ratio showed a downward trend year by year. The reason for this situation is the low utilization rate of traditional chemical fertilizers. The research shows that the utilization rate of nitrogen fertilizer in China is only 30% - 35%, phosphorus fertilizer is 15% - 20%, and potassium fertilizer is 35% - 40%. The loss of unused fertilizer causes serious pollution to the natural environment. According to the Research Report of Nanjing Institute of soil research, Chinese Academy of Sciences, there is a quick manual box. Every year, there are 1.235 million tons of nitrogen flow in China. It not only reflects the parameters into rivers and lakes, 494000 tons into groundwater and 2.99 million tons into the atmosphere

"China's total amount of chemical fertilizer and the amount of fertilizer applied per unit area are the first in the world, but the fertilizer utilization rate is only about 30%, and most of it has been lost. If the fertilizer utilization rate is increased to 50%, first, it can save costs, second, it will not pollute the environment, and at the same time, it will also improve food production. The popularization and application of slow-release fertilizer has changed the traditional fertilization method and improved the fertilizer utilization rate, which is the progress of fertilizer science and technology." Yuan Longping, an academician of the Chinese Academy of engineering, said. The establishment of the national slow and controlled release fertilizer engineering technology research center is of great significance to promote the sustainable development of China's agriculture, ensure national food security, reduce agricultural non-point source pollution, and build an energy-saving society, which will bring epoch-making changes to China's agriculture

it is reported that as the leading enterprise in the production of slow-release and controlled-release fertilizers in China and the supporting unit of the national slow-release and controlled-release fertilizer engineering technology research center, Jinzhengda group has long been committed to the promotion and application of slow-release and controlled-release fertilizers in China, established the world's largest slow-release and controlled-release fertilizer production base, and cooperated with the National Agricultural Technology Extension Service Center and other units to demonstrate and promote slow-release and controlled-release fertilizers in more than 20 provinces across the country, covering an area of 22million mu
