[0025] Please refer to Figures 2 to 4 A soilless cultivation device, comprising:

[0026] A hydroponic mechanism, comprising a hydroponic liquid tank 100 and a seedling tray 120, the hydroponic liquid tank 100 containing hydroponic liquid, and the seedling tray 120 floating on the hydroponic liquid in the hydroponic liquid tank 100;

[0027] A heat insulation mechanism, disposed below the hydroponic liquid tank 100, comprising a plurality of heat insulation plates 200, and adjacent two heat insulation plates 200 are detachably connected, and the heat insulation plate 200 is used for heat insulation of the hydroponic liquid tank 100.

[0028] Specifically, the soilless cultivation device provided by the application comprises a water culture liquid tank 100, a seedling raising tray 120 and a plurality of heat insulation plates 200. The water culture liquid tank 100 contains water culture liquid, which provides nutrition for seedlings. The seedling raising tray 120 is floated in the water culture liquid tank 100. The seedling raising tray 120 can be a foam box, a plastic box or the like. Preferably, the seedling raising tray in the application is a foam box. Since the density of the foam is small, the foam has an independent bubble structure, and the foam has low water absorption and good anti-permeation performance. The foam seedling raising tray 120 is floated in the water culture liquid tank 100, and the seedling raising tray 120 will not sink to the bottom of the water culture liquid tank 100. The plurality of heat insulation plates 200 are spliced together and attached to the bottom of the water culture liquid tank 100. The water culture liquid tank 100 is heat-insulated by the plurality of heat insulation plates 200. Adjacent two heat insulation plates 200 are detachably connected, which facilitates placement and replacement. The plurality of heat insulation plates 200 are provided to heat-insulate the water culture liquid tank 100. The heat insulation plates 200 have moisture-proof and waterproof performance, low thermal conductivity and good thermal performance. As the temperature of the greenhouse becomes higher and higher, the heat insulation plates 200 can insulate the heat radiation of the ground and the heat in the greenhouse due to the excellent heat insulation performance of the heat insulation plates 200. The temperature rise of the water culture liquid in the water culture liquid tank 100 caused by the heat radiation of the ground is avoided, so that the temperature of the water culture liquid in the water culture liquid tank 100 will not rise with the temperature rise of the greenhouse to a certain extent, the seedlings are prevented from being burned, and the survival rate of the seedlings is improved.

[0029] In a preferred embodiment, the heat insulation plates 200 are attached to the lower surface and the peripheral surface of the water culture liquid tank 100. The heat insulation plates 200 are polyurethane heat insulation layers.

[0030] Specifically, the heat insulation plates 200 can be perlite heat insulation layers, polyurethane foams and polyurethane heat insulation layers. Preferably, the heat insulation plates 200 in the application are polyurethane heat insulation layers. The heat insulation plates 200 have moisture-proof and waterproof performance, low thermal conductivity and good thermal performance. The heat insulation plates 200 are spliced together and attached to the bottom and the peripheral periphery of the water culture liquid tank 100. The water culture liquid tank 100 is heat-insulated by the heat insulation plates 200. As the temperature of the greenhouse becomes higher and higher, the heat insulation plates 200 can insulate the heat radiation of the ground and the temperature and heat in the greenhouse due to the excellent heat insulation performance of the heat insulation plates 200. The temperature rise of the water culture liquid in the water culture liquid tank 100 caused by the heat radiation of the ground is avoided, so that the temperature of the water culture liquid in the water culture liquid tank 100 will not rise with the temperature rise of the greenhouse to a certain extent, which is conducive to the growth of the seedlings and prevents the seedlings from being burned, and the survival rate of the seedlings is improved.

[0031] In a preferred embodiment, a support frame 210 is further arranged below the heat insulation mechanism, and the support frame 210 is used to increase the distance between the ground and the heat insulation mechanism.

[0032] Specifically, the support frame 210 can be an iron frame, a wooden frame, a stone pier, etc. As preferred, the support frame 210 in the present application is a stone pier. Since the greenhouse is a closed space and is directly exposed to sunlight, the temperature in the greenhouse will become higher and higher, and the ground surface temperature will also rise. The support frame 210 is arranged below the heat insulation mechanism, which increases the distance between the heat insulation mechanism and the ground by the support frame 210, thereby increasing the heat radiation distance from the ground to the heat insulation mechanism, weakening the heat radiation intensity of the ground to the hydroponic liquid tank 100, and further avoiding the temperature rise of the hydroponic liquid in the hydroponic liquid tank 100 caused by the heat radiation of the ground.

[0033] In a preferred embodiment, a water storage film is arranged in the hydroponic liquid tank 100, and the water storage film is used to place the hydroponic liquid. The water storage film is a plastic film.

As preferred, the water storage film in the present application is a transparent water storage film. A water storage film with a large area is placed on the opening of the hydroponic liquid tank 100, and the water storage film is supported down. The inner side of the water storage film is attached to the inner bottom of the hydroponic liquid tank 100, and at the same time, the part of the water storage film that exceeds the opening of the hydroponic liquid tank 100 is bent to the outer side wall of the hydroponic liquid tank 100 and is fixed by the fixing member 110. The water storage film has good waterproof performance and can prevent water from penetrating. The water storage film is placed in the hydroponic liquid tank 100, so that a water storage area is formed in the water storage film, which provides nutrients for the seedlings and supplements the nutrient elements of the seedlings.

[0035] In a preferred embodiment, the side wall of the hydroponic liquid tank 100 is provided with a fixing member 110, and the fixing member 110 is used to fix the water storage film.

[0036] Specifically, the fixing member 110 can be a hook, a buckle, a cloth tape, a clip, etc. As preferred, the fixing member 110 in the present application is a clip. The fixing member 110 is arranged on the side wall of the hydroponic liquid tank 100, and the part of the water storage film that exceeds the opening of the hydroponic liquid tank 100 is bent to the outer side wall of the hydroponic liquid tank 100 by the fixing member 110 and is fixed on the side wall of the hydroponic liquid tank 100 by the fixing member 110. The outer appearance is beautiful and convenient for the arrangement of the water storage film. For example, during the arrangement process, if the position is not enough due to improper arrangement, the water storage film cannot be laid in the hydroponic liquid tank 100 at this position. The fixing member 110 can fix it to avoid such a situation.

[0037] In a preferred embodiment, a plurality of seedling grids 130 are arranged on the seedling tray, and a through hole 131 is arranged at the bottom of the seedling grid 130.

[0038] Specifically, a plurality of seedling grids 130 are arranged on the seedling tray 120, and one seedling is placed in one seedling grid 130, which is convenient to take. After the roots of the seedling grow out, the roots are passed into the water culture liquid tank 100 through the through hole 131 arranged at the bottom of the seedling grid 130 to absorb nutrients, so that the roots of the seedling are more tenacious and are not easy to break, and the survival rate of the seedling is improved.

[0039] In a preferred embodiment, a nutrient liquid tank 300 arranged under the ground is further included, the nutrient liquid tank 300 and the water culture liquid tank 100 are provided with a water culture liquid inlet pipe 310 and a water culture liquid outlet pipe 320, and the water culture liquid is circulated between the nutrient liquid tank 300 and the water culture liquid tank 100 through the water culture liquid inlet pipe 310 and the water culture liquid outlet pipe 320.

[0040] Specifically, the water culture liquid in the nutrient liquid tank 300 is pumped into one end of the water culture liquid tank 100 through the water culture liquid inlet pipe 310, and the water culture liquid slowly flows to the other end of the water culture liquid tank 100 from the one end, in the process of flowing, the seedling absorbs the water culture liquid, and after the water culture liquid slowly flows to the other end of the water culture liquid tank 100 from the one end, the water culture liquid returns to the nutrient liquid tank through the water culture liquid outlet pipe 320, and the water culture liquid provides nutrients for the seedling in the process of flowing in the water culture liquid tank 100.
