Abstract
In order to explore the best fertilization amount in super rice cultivation,a plot experiment of different fertilization amounts was conducted in paddy field for early rice.The result shows that it has the highest yield for applying N of 625 kg/mu(average yield is 720.6 kg/mu) and lowest yield for applying N of 13.6 kg/mu(average yield is 625.0 kg/mu).The yield is decreasing along with the increase of fertilization amount.In the condition of previous tomato cultivation and straw-returning-field,the applying of 7～9 kg N/mu can reach best effectiveness and highest yield.
