| Abstract: | 【Objective】 To study the effects of applying different amounts of phosphate fertilizer on the yield. 【Method】 Phosphorus utilization efficiency of tomato under drip irrigation using Jinfan 1606 processed tomato as a test variety through field experiments.Based on the same nitrogen and potassium (N 240 kg/hm2, K2O 90 kg/hm2), five treatments were set up in the test: (1) P0: no phosphate fertilizer was applied; (2) P60: phosphate fertilizer (P2O5) was used at 60 kg/hm2; (3) P120: phosphate fertilizer (P2O5) is 120 kg/hm2; (4) P180: phosphate fertilizer (P2O5) is 180 kg/hm2; (5) P240: phosphate fertilizer (P2O5) is 240 kg/hm2. 【Result】 The results showed that compared with the treatment without phosphorus fertilizer, the application of phosphorus fertilizer significantly increased the phosphorus absorption of processed tomatoes, and the P absorption rate increased with the increase of phosphorus application, but the utilization efficiency of phosphate fertilizer decreased with the increase of phosphorus application.At the same time, the application of phosphate fertilizer significantly increased the yield of processed tomatoes, which increased 3.6%-7.4% compared with no phosphate fertilizer.When the amount of phosphate fertilizer was less than 120 kg/hm2, the yield of processing tomatoes increased with the increase of phosphorus application; and when the amount was over than that, the yield no longer increased significantly.The application of phosphate fertilizer had no significant effect on the quality of processing tomatoes. 【Conclusion】 Under this experimental condition, the suitable phosphorus application rate was 129.7 kg/hm2, and the optimal economic yield was 121 t/hm2. |
