This study designed the field plot test to examine the effects of fertilization on dry matter accumulation,nutrient uptake and yield of processing tomato under drip irrigation.The results showed that,compared with all phosphate fertilizer as basal,65% phosphate fertilizer as basal and 35% phosphate fertilizer as top dressing treatment（Optimization）before first fruiting period improved of processing tomato dry matter by 11.51% and yield increased by 3.59%,and improved the utilization rate of nitrogen,phosphorus and potassium fertilizer increased by 6.06,4.15 and 5.26 percentage points,respectively,when drip fertilization of all nitrogen in the whole growth period of processing tomato and drip fertilization of 70% potassium after first fruiting period.The yields of the treatments with drip fertilization of nitrogen and phosphate before first fruiting period and drip fertilization of nitrogen and potassium after first fruiting period were significantly less than that of the optimization,and fertilizer efficiency of the optimal treatment was also better than the drip irrigation formula fertilizer treatments.Drip fertilization of nitrogen and phosphate before first fruiting period and drip fertilization of nitrogen and potassium after first fruiting period increased processing tomato yield and improved the utilization rate of fertilizer.
