Description

Technical Field

[0001] The utility model relates to the technical field of sheds, in particular to a small steel-frame shed for growing flue-cured tobacco seedlings. Background Art

[0002] Floating seedling cultivation is the most common method of current flue-cured tobacco seedling cultivation. It is usually necessary to build a greenhouse outside the seedling cultivation pool. Most of the existing greenhouses are connected by welding, which makes it difficult to disassemble and reuse the greenhouse. In order to facilitate disassembly and assembly, there are also detachable greenhouses in the prior art. For example, the utility model with announcement number CN206442804U records a movable steel frame seedling greenhouse, including a greenhouse frame and a greenhouse film fixed on the greenhouse frame. The greenhouse frame includes a rectangular ground frame and an arch frame connected to the rectangular ground frame by plugging. The rectangular ground frame is formed by a pair of longitudinal enclosure rods and a transverse enclosure rod assembly connected to the two ends of the longitudinal enclosure rods by plugging. The longitudinal enclosure rods are provided with interval-arranged greenhouse rod inserts. During the installation process, the length and width of the seedling greenhouse are determined by the length of the longitudinal enclosure rods and the width of the greenhouse rods, and it is difficult to adjust according to the actual occupied space. In this regard, in order to overcome this technical problem, the utility model provides a flue-cured tobacco seedling greenhouse with a steel frame. Utility Model Content
