Abstract: In this study, plot experiment which included different nitrogen rates, different nitrogen topdressing stages and different ratios of npk was designed to study fertilizer application techniques for high yield, high quality and high benefit of late maturity japonica and glutinous rice cultivar “Wan Dao 68”.The results showed that 300.0~337.5kg/hm2 pure nitrogen were essential in yield production level above 10000 kg/hm2; The nitrogen topdressing stage was from inverse fourth stage to inverse third stage and the fitting time was in the last 10-day period of July while nitrogen fertilizer ratio of basal-tillering and panicle was 7:3; the suitable ratios of npk were 1:0.3:0.3~0.6.
