Abstract: The fertilizer application amount change trend was studied by referring to statistical yearbook and surveying on farmers’fertilization habit. This article analyzed the characteristics of fertilizer application increase in rice and provided references for“zero increase”of fertilizer in the production of rice and other crops. Statistics showed that the amount of fertilizer application showed an increasing trend year by year, the annual average growth rate was 1.387% during 2001 to 2015. The amount of fertilizer application on rice accounted for a big proportion in whole crop production. The growth rate of rice fertilizer amount from 2005 to 2015 was 55.4%, which was significantly higher than the physical volume growth rate (2.9%), the unreasonable N/P/K application was maintained. Based on this paper, to achieve the target of chemical fertilizer“zero increase”, the application of fertilizer should focus on the pure amount of fertilizer and follow the“four adjustments”and“four changes”.
