[Objective] The proper amount of nitrogen fertilizer was used in Sujing NO.815 and the fertilization method in tillering stage was groped in the test for providing basis for its high-yield cultivation.[Method] Randomized block design was used in two field subtests:subtest of nitrogen fertilizer application and subtest of different balanced fertilizer applied in tillering stage.[Result] The nitrogen rate for the maximum yield of Sujing No.815 was 270 kg/hm2.Application of balanced fertilizer increased the amount of productive tillers,but decreased the number of grain per ear,and finally influenced its yield formation.[Conclusion] The proper nitrogen rate applied in high-yield cultivation of Sujing No.815 by manual transplanting was 270 kg/hm2.And tillering stage dressing should be applied enough once and balanced fertilizer application wasn' t required.
