| Abstract: | In this paper, based on the monitoring data, the fertilizer application rates on rice during 1984 to 2000 in Guangdong province were studied. The effects of fertilization on rice yield, soil organic matter and soil nutrients were also discussed. Through analysis of the fertilization system such as different kinds of fertilizers, application periods, application methods, and the utilization rate of fertilizers, the rationality of fertilization was valued. In order to get higher yield and quality of rice, it is essential to take measures to improve the fertilizer potential. |
