Less than 9% of the world's arable land consumes 1/3 of the world's chemical fertilizer.
China's cultivated land accounts for 8% of the world's arable land, but it consumes 35% of the world's nitrogen fertilizer every year. The abuse of chemical fertilizer not only worsens the ecology of nitrogen oxide residues in agricultural products, but also directly aggravates air and water pollution, which is one of the main sources of haze pollution. It is urgent to pass legislation to limit abuse and improve utilization.
Yesterday, Wu Weihua, academician of the Chinese Academy of Sciences, member of the standing Committee of the CPPCC National Committee, vice chairman of the Central Committee of Jiusan Society, and professor of China Agricultural University, held a popular science lecture on "problems and challenges in the Construction of Agricultural Ecological Civilization in China" at Guangzhou No.2 Middle School.
Organic fruits and vegetables are the most popular food at present, but according to Wu Weihua, there is very little real organic food in our country. Wu Weihua said that in addition to polluting the soil and causing high nitrogen oxide residues in agricultural products, the abuse of chemical fertilizers. It is also one of the main sources of nitrogen oxide pollution in air and water. At present, haze pollution is spreading all over the country, and the abuse of chemical fertilizers is the main "accomplice" besides industrial production and automobile exhaust. The pollution of the water body can not be ignored, even affecting the water source of the middle route of the South-to-North Water transfer Project.
