LI Guangyu1, PENG Xianlong1, LIU Yuanying1, SHENG Dahai1, BAO Yong2 (1. Resources and Environmental Sciences College, Northeast Agricultural University, Harbin 150030, China; 2. Jiansanjiang Sub-bureau Farm, Fujin Heilongjiang 156100, China)  
The experiment was conducted to study the effects of applying N at later growth stage on rice quality and yield under the condition of applying the same amount of N (100 kg·hm-2) using field plot method. The results showed that the effects of application N at later growth stage on brown rice rate, milled rice rate, protein content, amylose content and other quality indexes were all unobvious, and only the head rice raised 4.4%-9.9%. There were different effects on chalkiness of rice by top-fertilization at different maturity degree of young plants, the chalkiness of rice could be lower if top-fertilization at the maturity degree of young plants was put off. In a word, there were no effects of applying N at later growth stage on rice milling quality and surface quality, and the influence of applying N at later growth stage on the quality of taste was not obvious.
