Abstract
Rice yield and grain quality of Shanyou 63 and Zhendao 88 were investigated by applying nitrogen at different growth stages with fertilizing 300 kg pure nitrogen per hectare during whole growth duration. The results showed that the nitrogen application with the ratio of basal fertilizer∶tiller fertilizer∶spikelets protecting fertilizer of 4∶2∶4 could not only enhance productive stems, increase photosynthetic rate and nitrogen content of leaves at heading stage, promote matter production from heading to maturity, and increase yield and nitrogen utilized efficiency, but also improve rice milling quality, reduce chalky percentage and increase crude protein content in grains.
