The field position fertilization test was conductd on new terraced field in the case of natural rainfall,the results showed that(1)in the different treatments,the most significant treatments on yield increase was the mixture of organic fertilizer and inorganic fertilizer,the next was the mixture of nitrogen and phosphours,the yield of only apply phosphours was equivalent to the ckeck experiment.(2)the effects of crop biological characters on the different fertilization were similar with yield's.Because fertilization may increase the amount of stems and leaves,it would increase the biomass.(3)on the new terraced fields,increasing the amount of fertilizer,especially organic fertilizer applied and paying attention to its mixture with chemical fertilizer were the main way for improving water used efficiency and yield of the crops.
