In the embodiment of the present disclosure, the structural parameters such as the number and the width of the central seam 21 and the side seams 22 are determined according to the actual size and the structure of the greenhouse, and are not limited to the foregoing specific limitations.

In some embodiments, a central seam 21 is reserved on one side or two sides of the top 101 of the greenhouse supporting frame 10. The arrangement of the film 20 is determined according to the reserved position of the center seam 21, but is not limited.

In a first specific application example, as shown in fig. 1, a first central seam 211 is reserved on the first side surface 102 of the greenhouse supporting frame 10; the film 20 includes a first film 23 and a second film 24; the first film 23 is laid from the upper edge of the first central seam 211 upwards to the second side surface 103 by passing around the top 101 of the greenhouse support frame 10, and then downwards to the lower edge of the second side seam 222 of the second side surface 103, and forms an overlap of a first preset width with a film (such as the second bottom film 27 shown in fig. 1) below the second side seam 222; the second film 24 is laid from the lower edge of the first middle seam 211 to the lower edge of the first side seam 221 of the first side surface 102 of the greenhouse supporting frame 10 and forms an overlap (the edge seam overlapping part 252 shown in fig. 1) with a first preset width with the film (the first bottom side film 26 shown in fig. 1) below the first side seam 221; and extends from the lower edge of the first center seam 211 up to the upper edge of the first center seam 211 and overlaps the first film 23 by a second predetermined width (the center seam overlapping part 251 shown in fig. 2); the second film 24 is fixedly attached to the lower edge of the first central slit 211.

In the embodiment, the central seam 21 is reserved on only one side of the greenhouse support frame 10, so that the width of the central seam 21 can be properly larger, and the ventilation quantity is ensured. For example, the width of the center slit 21 in this embodiment is 80 to 150cm, and the second predetermined width is 30 to 50cm. For another example, the width of the central slit 21 in this embodiment is 100 to 120cm, and the second predetermined width is 40 to 50cm. Generally, the second predetermined width is in a direct proportion relation with the width of the central seam 21, and the larger the width of the central seam 21 is, the larger the second predetermined width is, so as to ensure the sealing property when the central seam 21 is covered with the film.

In this embodiment, the first predetermined width is 30 to 50cm, which ensures the sealing property of the side seam 22. Optionally, the first preset width is 40cm. Generally, the first predetermined width is proportional to the width of the side seam 22, and the larger the width of the side seam 22 is, the larger the first predetermined width is, so as to ensure the sealing property when the film is covered on the side seam 22.

The first film 21 comprises a first sub-film and a second sub-film, and the first sub-film is laid from the upper edge of the first middle seam 211 to the upper edge of the second middle seam after passing the top 101 to the second side surface 103 of the greenhouse support frame 10. The second sub-film is laid from the lower edge of the second middle seam to the lower edge of the second side seam 222 of the second side surface 103 of the greenhouse support frame 10 and forms an overlap (shown as a side seam overlapping part 252 in fig. 1) with a first preset width with a film (shown as a second bottom side film 27 in fig. 1) below the second side seam 222; the lower edge of the second middle seam extends upwards to the upper edge of the second middle seam and is overlapped with the first sub-film with a second preset width; the second sub-film is fixedly connected with the lower edge of the second middle seam so as to be opened and limited when the second middle seam is opened. In the first specific application example, the present embodiment is implemented by modifying only the first film 23, and the arrangement of the second film 24 is not changed. The second side seam is not shown and may be provided with reference to the structure of the first center seam 211 in fig. 1.

In this embodiment, the middle seams 21 are reserved on both sides of the top 101 of the greenhouse supporting frame 10, so the width of the middle seam 21 on each side can be properly smaller, and the ventilation volume is ensured. For example, the width of the center slit 21 of the present embodiment is 50 to 120cm, and the preset width is 30 to 50cm. For another example, the width of the central slit 21 in this embodiment is 80 to 100cm, and the preset width is 30 to 40cm.

In the embodiment of the disclosure, the larger the width of the central seam 21 is, the larger the preset width can be controlled to be, and the sealing performance is ensured.
