Abstract
7 nitrogen fertilizer treatments of 0, 6, 9, 12, 15, 18, 21 kg / 667m2 were applied on the Yanliangyou 2208 and Yangliangyou No.6 during the whole growth period, the effects of nitrogen fertilizer application on yield and quality of rice were studied. The results showed that increasing nitrogen application within a given range improved rice yield. Yanliangyou2208 and Yangliangyou No.6 had maximum yields with 12 kg / 667 m2 nitrogen fertilizer treatment. The amount of nitrogen application had a certain regulation effect on the quality of rice with no obvious pattern. Growth period of rice was prolonged with the increase of nitrogen application.
