随着现代农业的发展,化肥在农业生产中日益显示其重要作用。世界各国农业现代化的过程,是以先进的工业装备农业的过程。工业装备农业的渠道主要有二条:一是机械化,二是化学化。机械化可以大幅度提高农业劳动生产率;而单位面积产量的高与低,则主要由矿物营养、品种以及其他因素决定的。大量增施化肥是争取高产的重要措施之一。根据有关资料介绍,第二次世界大战以后,世界化肥产量大约每十年增加一倍;战后美国农业的增产,30—40％归因于增施化肥,而玉米的增产,有50—60％是增施化肥的结果。
With the development of modern agriculture, fertilizer has increasingly shown its important role in agricultural production. The process of agricultural modernization in all countries in the world is based on the process of equipping advanced agriculture with industry. There are two main channels for industrial equipment agriculture: one is mechanization, and the other is chemicalization. Mechanization can greatly improve agricultural labor productivity; and high and low yield per unit area, mainly by the mineral nutrition, variety and other factors. Large-scale fertilization is one of the important measures for high yield. According to relevant information, after the Second World War, the world’s chemical fertilizer production about every 10 years doubled; the post-war American agricultural output, 30-40% attributed to the increase of fertilizers, and corn production, there are 50-60 % Is the result of fertilizers.
