[0002] The fast growth characteristics of Pennisetum giganteum endow it with certain commercial value, and in the northwest region of China, the cultivation of Pennisetum giganteum has been continuously introduced. On the one hand, Pennisetum giganteum can improve the soil environment in the northwest, and on the other hand, it can be used as an excellent livestock feed. However, the temperature difference between day and night is relatively large in spring, autumn and winter in the northwest region. When the temperature is lower than 5°C, the seedlings of Pennisetum giganteum will stop growing, so certain heat preservation measures need to be taken when cultivating the seedlings of Pennisetum giganteum. Therefore, in the northwest region, the cultivation of Pennisetum giganteum seedlings needs to be carried out in a greenhouse to provide a good growth environment for the seedlings of Pennisetum giganteum. However, the side part of the traditional greenhouse heat preservation film is fixed on the ground. When the heat preservation film is covered on the seedlings of Pennisetum giganteum, due to the fast growth of Pennisetum giganteum, the situation of the heat preservation film pressing the seedlings is likely to occur. How to solve this problem is a technical problem that needs to be solved in this field. Content of the Utility Model

[0024] The fast growth characteristics of Pennisetum giganteum make it have certain commercial value. In the northwest region of China, the cultivation of Pennisetum giganteum has been continuously introduced. On the one hand, Pennisetum giganteum can improve the soil environment in the northwest, and on the other hand, it can be used as an excellent livestock feed. However, the temperature difference between day and night is relatively large in spring, autumn, and winter in the northwest region. The seedlings of Pennisetum giganteum stop growing when the temperature is lower than 5°C, so certain heat preservation measures need to be taken when cultivating the seedlings of Pennisetum giganteum. Therefore, in the northwest region, the cultivation of Pennisetum giganteum seedlings needs to be carried out in a greenhouse to provide a good growth environment for the seedlings of Pennisetum giganteum. However, the side part of the traditional greenhouse heat preservation film is fixed on the ground. When covering the heat preservation film on the seedlings of Pennisetum giganteum, due to the fast growth of Pennisetum giganteum, the situation of the heat preservation film pressing the seedlings is likely to occur. How to solve this problem is a technical problem that needs to be solved in the art.

[0025] In view of this, the present application provides a heat preservation device for Pennisetum giganteum seedling cultivation applied to a greenhouse, which can make the height position of the heat preservation film adjustable, and while the heat preservation film plays a role in keeping the seedlings of Pennisetum giganteum warm, it can avoid the heat preservation film pressing the seedlings to a certain extent.

[0026] An exemplary heat preservation device for Pennisetum giganteum seedling cultivation applied to a greenhouse is as follows:

[0027] Figure 1 The following shows a schematic structural diagram of a heat preservation device for Pennisetum giganteum seedling cultivation applied to a greenhouse provided by an embodiment of the present application. The present application provides a heat preservation device for Pennisetum giganteum seedling cultivation applied to a greenhouse. In one embodiment, asFigure 1 As shown in the figure, the device is applied to the greenhouse 1. The Pennisetum giganteum seedling-raising heat preservation device includes: a plurality of support rods 2, a plurality of connecting pieces 5, a plurality of heat preservation films 6, a cross beam 7 and a suspension piece 8. A plurality of support rods 2 are erected in the greenhouse 1. The top of the support rod 2 is connected to the top of the greenhouse 1. A seedling-raising planting area 4 is arranged between adjacent support rods 2. The seedling-raising planting area 4 is used for planting Pennisetum giganteum seedlings. A plurality of connecting pieces 5 are arranged on the support rods 2 in the vertical direction. A plurality of connecting pieces 5 are arranged on the supporting structure 3 on the side of the greenhouse 1 in the vertical direction. A plurality of heat preservation films 6 are connected to the plurality of connecting pieces 5 to cover the seedling-raising planting area 4. The cross beam 7 is respectively connected to the support rod 2 and the supporting structure 3. The suspension piece 8 is partially connected to the cross beam 7. One end of the suspension piece 8 is connected to the heat preservation film 6.

[0028] In the application of this embodiment, the support rod 2 and the connecting piece 5 play a role in supporting and fixing the heat preservation film 6, so that the heat preservation film 6 can stably cover the seedling-raising planting area 4, and Pennisetum giganteum seedlings are planted and cultivated in the seedling-raising planting area 4. The support rod 2 can also play a role in supporting the greenhouse 1, and the top of the greenhouse 1 will also play a role in positioning the support rod 2. By connecting the heat preservation film 6 to the connecting pieces 5 at different heights, the height position of the heat preservation film 6 can be adjusted. Refer to Figure 1 , for the heat preservation film 6 close to the supporting structure 3, one side is connected to the connecting piece 5 of the supporting structure 3, and the opposite side is connected to the connecting piece 5 of the support rod 2. For the heat preservation film 6 located between two support rods 2, both sides are respectively connected to the connecting pieces 5 of the support rods 2. The cross beam 7 can play a role in stably fixing the support rod 2 and provide a bearing for the suspension piece 8. The suspension piece 8 hangs the heat preservation film 6 from above to prevent the middle of the heat preservation film 6 from collapsing, further stabilizing the position of the heat preservation film 6, so that while the heat preservation film 6 plays a role in keeping the Pennisetum giganteum seedlings warm, it can avoid pressing the seedlings to a certain extent. Since the growth rate of Pennisetum giganteum is fast, the height position of the heat preservation film 6 is adjustable, so as to adapt to Pennisetum giganteum seedlings of different heights.

[0029] Specifically, the plurality of support rods 2 are arranged at equal intervals with respect to each other. The plurality of connecting pieces 5 on the support rod 2 are arranged at equal intervals along the length direction of the support rod 2. The plurality of connecting pieces 5 on the supporting structure 3 are arranged at equal intervals along the length direction of the support rod 2.

[0030] In an embodiment, the number of the connecting pieces 5 arranged on the support rod 2 is the same as the number of the connecting pieces 5 arranged on the supporting structure 3. That is, at the same height position corresponding to a certain connecting piece 5, other support rods 2 and the supporting structure 3 are both provided with connecting pieces 5. For example: the first ground height is equal to the second ground height. The first ground height is the ground height of the connecting piece 5 at the lowest position on the support rod 2, and the second ground height is the ground height of the connecting piece 5 at the lowest position on the supporting structure 3.

[0031] In one embodiment, the suspension member 8 is a cable, and one end of the cable is connected to the heat preservation film 6 to suspend the heat preservation film 6.

When it is necessary to adjust the height of the heat preservation film 6, loosen the connection between the heat preservation film 6 and the connecting member 5, untie the other end of the suspension member 8, and then pull the suspension member 8. The pulley 9 can prevent friction between the cable and the cross beam 7. After pulling the suspension member 8 to make the heat preservation film 6 reach a certain height, then connect the side edge of the heat preservation film 6 with the connecting member 5.

[0032] Specifically, fixing rings are provided at the side edges of the heat preservation film 6, and the fixing rings are connected to the connecting member 5, which can make the connection between the heat preservation film 6 and the connecting member 5 more convenient.

[0033] In one embodiment, the ground height of the connecting member 5 at the highest position on the support rod 2 is less than or equal to 2 meters, and the ground height of the connecting member 5 at the highest position on the support structure 3 is less than or equal to 2 meters, so that the staff can reach the connecting member 5 at the highest position, and the seedling cultivation of giant miscanthus is completed when the seedlings grow to more than one meter, and there is no need to set the connecting member 5 too high.
