Abstract: In order to account for project of fertilization Guixiangzhan,and probe into relationship of different levels of fertilizer application and effect of various factors of production and quality. This thesis studied on the effects of the usage of massive elements which included nitrogen,phosphorus,Potassium and silicon on yield and quality of Guixiangzhan.After delete the unapparent factors underα= 0.5 level,the analytic results showed that when the usages of Urea,Super phosphate,Potassium chloride and Sodium silicate were 26,0,48,56 g/ m²,the maximum yield was 5 352.6 kg/ ha.The influences to the yield in single factors are P > N,and K,Si have little influence underα= 0.5 level;The influences to the yield in compound factors are:the product of Kand Si has a positive effect on yield > the product of P and K has a negative effect on yield > the product of P and Si has a negative effect on yield.Besidesthe relativities of each factor are calculated.

Key words: Aromatic rice, Yield, Quality, Nitrogen, Phosphorus , Potassium, Silicon
