在农业上, 尿素是一种中性速效高含氮量化肥。其特点是缩二脲含量低, 无色、无味、无臭、易溶于水、易施用、颗粒均匀、饱满圆润、粉尘少, 是目前固体氮肥含氮量最高的一种。除作追肥以外, 在农业上, 尿素还有其它多种用途, 如调节花量、疏花疏果、水稻制种和防治虫害等北京翻译公司。
In agriculture, urea is a kind of neutral-type chemical fertilizer which is highly efficient and with high nitrogen content. It is characterized by low content of biuret, few dusts as well as even, plump and smooth particles. It is without color, smell and is odorless. It can easily be solved in water and be applied.

Chemical fertilizers are the key symbols of modern agriculture. At present, China is vigorously popularizing the use of organic fertilizers. In spite of this fact, in order to make sure the sustainable development of agriculture and satisfy the ever-growing wants and needs on agricultural products, it is expected that, in the future, chemical fertilizers will still be the principal parts of fertilizers and the industry of chemical fertilizer will be booming. As one of the most major kinds of chemical fertilizers, urea approximately accounts for more than 30% of the consumption of chemical fertilizers in our country. In addition, as the consumption structure of chemical fertilizers is more and more optimized and the market demand on high-concentration nitrogenous fertilizer with urea increases, the wants and needs of urea will be further enlarged.
