Abstract: This thesis studied on the effects of the usage of massive elements which included nitrogen、phosphorus、potassium and silicate on yield and quality of one aromatic hybrid rice combination, PeizaRuanxiang. The results showed that, with increase of nitrogen fertilizer level , yield、 effective panicle and whole grain rice rates enhanced; With increase of phosphorus fertilizer level, yield、effective panicle and 1000-grain weight droped；the potassium chloride fertilizer levels had no obvious influence to the yield, the effective panicle , the grains per panicle and the burliness rate；With increase of silicate fertilizer levels, the whole grain rice rate and the degree of chalkiness droped.
