Embodiment 1

[0038] A kind of near-distance far-infrared heating seedling raising device provided in this embodiment has a structure such as Figure 1-4 As shown, it includes insulation layer 1, reflective layer 2, isolation layer 3 and far-infrared heating layer 4 from bottom to top. The far-infrared heating layer 4 is supported by heating coating 10 (graphene coating), PET layer 9 and protrusions. Point 7 constitutes, the PET layer 9 wraps the graphene coating in the middle to improve the service life of the graphene coating, and the upper surface of the PET layer 9 is provided with raised support points 7 such as Figure 4 As shown, the upper end of the raised support point 7 on the upper surface of the PET layer 9 is provided with a seedling raising tray 5;

[0039] The middle part of the seedling hole in the seedling tray 5 and the lower surface of the far-infrared heating layer 4 are respectively provided with a temperature sensing device 6;

[0040] The thermal insulation layer 1 o...

Abstract

The invention discloses a close-range far infrared heating seedling raising device which sequentially comprises a heat preservation layer, a reflecting layer, an isolating layer and a far infrared heating layer from bottom to top. The far infrared heating layer is composed of a heating coating, a PET layer and protruding supporting points, the PET layer wraps the heating coating in the middle, the protruding supporting points are arranged on the upper surface of the PET layer, and the upper ends of the protruding supporting points on the upper surface of the PET layer are provided with seedling raising trays; temperature sensing devices are respectively arranged in the middles of seedling raising holes in the seedling raising trays and on the lower surface of the far infrared heating layer. Compared with a whole shed heating mode, the close-range far infrared heating seedling raising device can directly heat the seedling raising trays as well as culture mediums and plant seedlings on the seedling raising trays, the heating distance is shortened, the heating space is narrowed, and the energy utilization rate is improved.

Description

technical field [0001] The invention relates to a short-distance far-infrared heating seedling raising device, which belongs to the technical field of seedling raising. Background technique [0002] With the development of facility agriculture, glass greenhouses have been widely recognized, but the efficient heating of glass greenhouses has always been a problem to be solved. Glass greenhouses generally adopt the method of heating the entire shed, first heating the entire space of the glass greenhouse with external heat, and then using heat conduction to keep the plants in the shed within a certain temperature range. Heating the whole shed not only needs to heat the space away from the plants, but also expands the contact area between the heat source in the shed and the external cold source, thereby accelerating the loss of heat. [0003] Therefore, developing a safe, energy-saving, efficient and controllable heating seedling raising device has become a technical problem to...
