Tianjin Protected Vegetable Cluster

Tianjin's protected-vegetable cluster entered the national construction list in 2024. Beichen has distinct greenhouse operations in Xiditou, Shuangkou and Shuangjie: tomatoes were growing in Hongda Agriculture's first-phase smart greenhouses in 2024; Yimu Yucai's aquaponic site in Shuangkou was documented on the ground and the firm still appeared on the city's 2024 technology-SME list; and Shuangjie Growers' Cooperative was still growing fruit and vegetables in 2025. These are not one park or one grant award, and earlier reporting is not a current production figure. Buyers should check seedling lots, growing inputs and climate records, post-harvest temperatures, grading and any processing licence.
