Abstract

An experiment was carried out to study the effects of nitrogen management on rice quality with hybrid rice Chuanxiangyou 9838 in winter paddy field. The results showed that the nitrogen application amount and nitrogen distribution had no significant effects on brown rice rate, head rice rate, chalky rice rate, gel consistency and amylose content; the nitrogen application amount had highly significant negative correlation with chalkiness degree and highly significant positive correlation with protein content, but had no significant correlation with length-width ratio. The nitrogen distribution has different effects on chalkiness degree in 2011 and 2012, and had no significant correlation with protein content.
