Chinese
grain production and
fertilizer use were temporally and spatially analyzed in terms of the experimental data and
the results of investigation. It has been realized that the
fertilizer use is one of the great achievements in
grain production in China in the 20th century. The average rate of contribution of fertilizer use to grain production is 46.43 per cent. Using one ton of fertilizer can increase 8.84 tons of grain. The output of grain and the amount of fertilizer use will continuously rise in China in the 21st century. It is estimated that the increase of 100 million tons of grain output will at least need the increase in use of 10.2211.08 million tons of fertilizer. It is necessary to carry out the strategic distribution of continuously developing the eastern plain, increasingly developing the central plateau and exploiting the western frigid plateau and desert region in order to realize the sustainable development of grain and the high efficiency of fertilizer use. The production of grain with high quality and special use should be strengthened in each region mentioned in the above framework for purpose of raising the share rate of the domestic grain in the market.
