在农业史上,化学肥料的使用为期尚短。1830年智利硝石首次运往欧洲,过磷酸钙的生产始于1843年,钾肥于1861年开始生产,而氮肥则于1902年才第一次制造。在化肥工业发展初期,产品单调,养分含量较低。然而,它对于农业生产却起了巨大的促进作用。随着农业生产的发展,化肥消费量也不断增加。1905年世界化肥的消费量大约为1.9百万吨(指有效成分,下同),到了1970—1971年度则增长到68.2百万吨。其中,N
In the history of agriculture, the use of chemical fertilizers is short-lived. Chilean saltpeter was first shipped to Europe in 1830, the production of superphosphate began in 1843, potash production began in 1861, and nitrogen fertilizer was first produced in 1902. In the early days of the fertilizer industry, the product was monotonous with low nutrient content. However, it has played a huge role in promoting agricultural production. With the development of agricultural production, the consumption of fertilizers has also been increasing. In 1905, the world’s consumption of fertilizers was about 1.9 million tons (referring to the active ingredients, the same below) and by 1970-71 it increased to 68.2 million tons. Among them, N.
