| Abstract: |
| This paper experimentally studied the efficacy of integrating fertilization with drip irrigation for improving the quality and yield of processing tomato based on the optimization method “3414” in an attempt to find an optimal irrigation and fertilization combination to sustain the tomato production. The results showed that increasing the application of macronutrients nitrogen (N), phosphorus (P), potassium (K) and micronutrients (MN) could significantly bolster tomato growth. Increasing P application alone together with MN considerably enhanced the investment-return ratio, while increasing N and K had no significant effect on tomato production. Meanwhile, reducing N and P resulted in a reduction in yield. It was also found that increasing K and MN improved food quality by, example, increasing sugar-acid ratio, reducing nitrate accumulation, promoting soluble solid formation and contrasting color difference in the fruit. In summary, increasing P and K and MN under drip irrigation could significantly improvefruit yield and quality. |
