随着人口的增长,对农产品的需求量亦随之增加。尽管农作物的种植面积仅占陆地面积的10％,但再要增加耕地面积是极其有限的。因此,要满足人类对农产品不断增长的要求,将主要依靠提高单位面积产量。而肥料是提高单产的重要因素之一。目前,世界上约1/4人口的食用农产品靠合理施肥的增产部分来提供,无机肥料对增加人类食品具有很重要的意义。没有无机肥料生产和应用水平的不断提高,农业生产的集约化是不可思议的。
As the population grows, the demand for agricultural products also increases. Although the area planted with crops is only 10% of the land area, increasing the area of arable land is extremely limited. Therefore, to meet the growing demand of mankind for agricultural products, we will mainly rely on increasing the yield per unit area. Fertilizer is one of the important factors to increase yield. At present, about 1/4 of the world’s population of edible agricultural products is provided by the increased production of rational fertilization. Inorganic fertilizers are of great importance to human food. Without the continuous improvement of the level of production and application of inorganic fertilizers, the intensification of agricultural production is inconceivable.
