| Abstract: In order to break through the single restriction of the agricultural production mode and overcome the influence of continuous cropping on soil, ecology and crop yield, a green and efficient breeding mode of ecology tomato–fish was summarized after studying and analyzing the advantages and disadvantages of the traditional vegetable–aquatic symbiosis system. The ecosystem of tomato–fish symbiosis was structured by taking the border as the nursery and the ditch as the pond, which mode vegetable–fish and aquatic– dry farming combinet and got high efficient production. After the application of technologies which contained the selection of cultivars, ditch patching, drip irrigation and water filling, shelter and shade, timely harvesting and fish stock mixing, drainage, irrigation and drying, precise baiting, and fishing, the comprehensive benefit of the production of 667 m2 of tomato–salmon per growing season was between 9 500～10 500 yuan. In addition, the quality of tomatoes and salmon had been improved. Compared with the conventional cropping field of tomato, although the planting area had been reduced by 10%～15%, the total income had increased by 10%～15%, and the overall production efficiency had been significantly improved. |
