Abstract: With Dong Ling Bai , through the methods of field experiment、chemical analysis and biological statistics, the effects of applying N、P、K、Zn fertilizer on forming law of yield and the absorption of N、P、K and nutrient quality were researched.The resualts were as foilwings: (l)The relations of the concentration and the amount of absorption and accumulation of N、P、K and applying fertilizer were analyzed, the ralations of the changing regulation of absorption rate and applying fertilizer were analyzed.The absorption requirements of N、P、K、Fe、Mn、Cu、Zn of 1000kg/day were offered.(2)With the condition of different fertilizer, the relations of the dry matter content and the amount of nutrient absorption of N、P、K and days were analyzed by the equation: Y= a+bx+cx2+dx3.The fastest rate and appearance time of absorption of N、P、K and accumulation of dry matter were discovered.(3)N、P、K fertilizer increased the fresh grass yield significantly, 50.2% by N fertilizer, 36.4% by P fertilizer, 13.2% by K fertilizer.

Key words: Silage Maize, Banlance Fertilizer, Yield, Nutrition absorption law
