Currently as China's accelerating development of agricultural industrialization and the increase of the agricultural production investment, the demand for chemical fertilizers increases year after year. Simultaneously as China's scientification in fertilization and fertilization ratio of the nitrogen, phosphorus, and potassium fertilizer tending to be reasonable, the chemical fertilizer demand structure will possibly change, the chemical fertilizer market environment will also change, the chemical fertilizer industry will run to the direction of high efficiency and environmentally no harm. Comparing to ordinary urea, large urea has many merits. These merits include big rime, glabrous pellet, smooth and well-mixed, not easy to crush or agglomerate in moist environment, suitable for long distance bulk transport and storage, and so on.
