Abstract: To clarify the suitable application rate of the soluble ammonium polyphosphate fertilizer for tomato,the nitrogen(N) rates of soluble ammonium polyphosphate fertilizer on yield,quality,N uptake and distribution,N balance and N utilization efficiency of autumn-winter tomato were studied in a plastic greenhouse.The results showed that the yield of tomato was the highest at 137.8 kg/ha and the fruit weight was the highest at 116 kg/ha.The most appropriate N rate for tomato quality was 116 kg/ha.As the N uptake of tomato roots and stems,the difference between treatments was not significant;the most appropriate nitrogen rate for tomato fruit and whole-plant were 71.39,84.39 kg/ha respectively.The nitrogen utilization efficiency(NUE) was higher than other treatments at 116 kg/ha.For this treatment, the apparent loss of nitrogen was 113.75 kg/ha.In summary,the most appropriate nitrogen rate for a higher autumn-winter tomato yield was at 116 kg/ha and the NUE was 27.6% under this soil fertility.

Key words: Ammonium polyphosphate, Soluble fertilizer, Facilities tomatoes, Nitrogen uptake, Nitrogen utilization efficiency
