Abstract
The experiments were carried out under pot cultural condition with Indica cultivar Yangdao 6 and Japonica cultivar Mippomadare. By treatments of N application date applied, differed substance and energy hull growth needed were attained. Effect of N application date on hull size (hull length, hull width and hull area), weight and plumpness (hull weight per unit area) at different positions of the panicle in rice were analysed. The results were as follows: ① Compared with no fertilizer, N application of tiller promoting would result in bigger size of hull and heavier hull weight on different positions of the panicle, especially lower parts of primary and secondary branches of the panicle. But effect on hull plumpness varied among two cultivars; N application of spikelet promoting, spikelet sustaining or redundant fertilization would result in smaller hull size,lighter hull weight and smaller hull plumpness on different positions of the panicle, especially upper or middle parts of primary and secondary branches of the panicle, regardless of different rice cultivars. Effect of basal fertilization on hull characters had difference between two cultivars. ② Promoting hull growth and development was beneficial to substance accumulation of grain, and would result in increment of length, width, thickness, volume and weight of brown rice respectively, and heavier grain weight was attained in the end.
