| 摘 要： | 采用田间小区试验的方法，设置不同施氮量、不同追氮时期和不同氮磷钾比例的试验，研究沿淮地区迟熟中粳糯稻“皖稻68”高产优质高效的施肥技术。结果表明，产量10000kg/hm2以上生产水平需施纯氮300.0～337.5kg/hm2，氮肥基蘖肥与穗肥比例为7:3条件下的追氮时期在倒4叶至倒3叶期，时间在7月下旬；氮磷钾比例在1:0.3:0.3～0.6为宜。

| 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. |
