Greenhouse for test

The utility model relates to a greenhouse for tests. Comprising a greenhouse frame covered with transparent base materials, and a plurality of experiment areas are defined in the greenhouse frame through the transparent base materials; a carbon dioxide discharge branch pipe connected with a carbon dioxide waste gas pipeline of a coal chemical enterprise is arranged in the experiment area, and a greenhouse roof fan is arranged at the top of the greenhouse frame corresponding to the experiment area; the device has the advantages that the experiment cost is reduced, carbon dioxide waste gas is recycled, the utilization efficiency of land in the greenhouse is improved, and the concentration of carbon dioxide is accurately controlled. 本实用新型涉及一种试验用温室大棚；包括覆盖有透明基材的大棚框架，所述大棚框架内部通过透明基材围成若干个实验区；所述实验区内设有与煤化工企业的二氧化碳废气管道相连的二氧化碳排放分管，实验区相对应的大棚框架顶部设有棚顶风机；具有降低实验成本、对二氧化碳废气再利用，以及提高温室大棚内土地的利用效率，以及对二氧化碳浓度进行精准控制的优点。
