Under field conditions,effects of different row spacings on matter transforming and grain filling characteristics were studied in Zhengzhou experimental farm of Henan province.The result indicated that row spacing could influence the dry matter production and transforming efficiency.The highest dry matter production came from the row spacing of 15 cm,and the lowest from 30 cm.Spike axis and husk had the lowest contribution rate to grain dry matter accumulation,stalk and sheath the highest,and leaves the middle.The highest total dry matter transforming amount to grain was from the row spacing 20 cm,and the lowest from 30 cm.Besides,grain filling course was imitated by logistic equation.In all,20 cm row spacing was benefitial to 1 000-grain weight.
