Abstract: The effects of different fertilization application on rice main pests, diseases and yields of rice were compared by using rice cultivars Zhejing 88 and Chunyou 84 as materials. The results indicated that the population and damage of rice main pests （planthopper and leaffolder） and main diseases （sheath blight and rice false smut） in the fields with modified fertilizer application were significantly lower than those in control fields. Meanwhile, the yields of Zhejing 88 and Chunyou 84 were increased by 7.21% and 1.68%, respectively. The effects of modified fertilizer application, which based on local fertilization application of Xiaoshan district in Hanzhou city, the modified fertilizer application including nitrogen fertilizer applied later, increasing the proportion of nitrogen application during panicle and granular periods and utilizing more phosphatic and potassic fertilizer.
