Description

Technical Field

[0001] The utility model relates to the technical field of tobacco seedling hydroponic culture, in particular to a tobacco seedling hydroponic culture floating plate which is convenient for root system observation. Background Art

[0002] Tobacco seedling hydroponics is a modern seedling cultivation technology. Its characteristic is that it provides stable and suitable growth conditions for tobacco seedlings through hydroponics, which is conducive to the rapid growth of seedlings and the development and growth of root systems. Tobacco seedling hydroponics uses foam plastic trays as seedling cultivation containers, so that the roots of tobacco seedlings absorb nutrients from the nutrient solution below and grow rapidly. In the cultivation process of tobacco seedlings, the root system is the main organ for plants to absorb water, nutrients and fix the plant body. Its growth condition directly affects the growth, development and yield of seedlings. During the seedling cultivation process, it is necessary to frequently observe the growth of the root system to adjust the hydroponics plan. At present, in order to observe the roots during the hydroponics of tobacco seedlings, the seedlings or the entire tray needs to be lifted, which is easy to cause damage to the tobacco seedlings. A tobacco seedling hydroponics and root system observation device disclosed in Chinese patent CN202223107985.7 has a glass wall on one side of the hydroponic box for observing the roots of tobacco seedlings, but the device has a high cost and is not suitable for root system observation in large-scale tobacco seedling cultivation.

The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and should not be construed as limiting the present invention.

[0027] Example 1

[0028] like Figures 1 to 4As shown, a tobacco seedling hydroponic floating board for convenient root observation includes a tobacco seedling hydroponic floating board 1, and a plurality of hydroponic grooves 2 are provided on the top of the tobacco seedling hydroponic floating board 1. The characteristics are as follows: assembly grooves 3 are provided on both sides of the tobacco seedling hydroponic floating board 1, and an assembly set 4 is installed inside the assembly groove 3. A root system observation lens barrel 5 is rotatably connected inside the assembly set 4, and a reflective plane mirror 6 is fixedly connected to the bending part inside the root system observation lens barrel 5.

[0029] The assembly groove 3 is cylindrical, and the inner diameter of the assembly groove 3 is adapted to the diameter of the assembly sleeve 4. One side of the assembly groove 3 is open. The top and bottom of the assembly sleeve 4 are fixedly connected to the limit ring 7. The diameter of the limit ring 7 is larger than the inner diameter of the assembly groove 3. The limit ring 7 is respectively fitted with the top and bottom surfaces of the tobacco seedling hydroponic floating board 1. By arranging assembled assembly sleeves 4 on both sides of the tobacco seedling hydroponic floating board 1, the root observation structure can be installed on both sides of the tobacco seedling hydroponic floating board 1 to observe the seedling roots at the bottom of the tobacco seedling hydroponic floating board 1, and the assembled root observation structure is convenient for disassembly and installation. The floating board is generally made of foam material and is easily damaged. After the floating board is damaged and scrapped, the assembled root observation structure can be replaced on a new floating board for use, so that the tobacco seedling root observation structure can be reused to reduce the loss cost. The two limit rings 7 can cooperate to limit the vertical degree of freedom of the assembly sleeve 4, so that the assembly sleeve 4 can be stably assembled in the assembly groove 3 for root observation.

[0030] like Figure 3 , 4 As shown, the diameter of the root observation lens barrel 5 is matched with the inner diameter of the assembly sleeve 4, and observation lenses 8 are fixedly connected to both ends of the root observation lens barrel 5. The bottom of the root observation lens barrel 5 is bent ninety degrees to one side, and a reflective plane mirror 6 is arranged at the bending part of the root observation lens barrel 5. The mirror surface of the reflective plane mirror 6 and the axes of the two ends of the root observation lens barrel 5 are at an angle of forty-five degrees. By arranging the root observation lens barrel 5 with the reflective plane mirror 6 on both sides of the tobacco seedling hydroponic floating board 1, the root system of the tobacco seedlings at the bottom of the tobacco seedling hydroponic floating board 1 can be observed from the top of the root observation lens barrel 5 by utilizing the reflection of the reflective plane mirror 6, so that the device can directly observe the root system of the tobacco seedlings from above the floating board, avoiding the situation that the tobacco seedlings need to be taken out of the culture water to observe the roots, which is easy to damage the roots, and the root observation method is more convenient and quick to operate.

[0031] The material of the tobacco seedling hydroponic floating board 1 is a polystyrene board, the friction coefficient between the assembly groove 3 and the assembly set 4 is greater than two, and the friction coefficient between the assembly set 4 and the root observation lens barrel 5 is less than 0.5. By limiting the friction coefficient between the assembly groove 3, the assembly set 4 and the root observation lens barrel 5, the assembly set 4 can maintain a stable assembly state after assembly, and the root observation lens barrel 5 can be rotated relative to the assembly set 4 to adjust the direction of the horizontal lens below, so that the root observation lens barrel 5 can adjust the bottom direction to achieve all-round root observation below the tobacco seedling hydroponic floating board 1.

[0032] like Figures 4 to 6 As shown, the outer side of the top of the root observation lens barrel 5 is provided with anti-slip grooves 9, and a marking pointer 10 is fixedly connected to one side of the top of the root observation lens barrel 5. The direction of the marking pointer 10 is adapted to the direction of the bent part of the bottom of the root observation lens barrel 5.

The brackets 11 are respectively located on both sides of the assembly groove 3. The force load of the material above the brackets 11 is greater than the total gravity of the floating board.

[0034] like Figure 3 , 4 As shown, the hydroponic tanks 2 are evenly distributed on the tobacco seedling hydroponic floating board 1 , and a connecting hole 12 is opened at the center of the bottom of the hydroponic tanks 2 .

[0035] During the tobacco seedling raising process of the utility model, the root system observation method is as follows:

[0036] 1) Insert the assembly sleeve 4 with the root system observation lens tube 5 into the assembly groove 3 to complete the fixation;

[0037] 2) filling the hydroponic tank 2 of the tobacco seedling hydroponic floating board 1 with a substrate for growing seedlings and tobacco seeds;

[0038] 3) placing the sown tobacco seedling hydroponic floating board 1 in nutrient water for cultivation;

[0039] 4) When it is necessary to observe the root system of the underwater tobacco seedlings, the user can focus his eyes on the observation lens 8 and rotate the root system observation lens tube 5 to observe the root system of the tobacco seedlings under the floating board.

When observing the root system of the tobacco seedlings, the lighting lamp is started to illuminate the root system of the observed tobacco seedlings, so that the device can observe the root system of the tobacco seedlings more clearly, and avoid the situation of the tobacco seedlings being unable to be clearly observed due to the dim light under the floating plate.

[0042] Example 3

[0043] The present embodiment is different from the first embodiment in that the opening diameter at the top of the root system observation lens tube 5 is increased, and the observation lens 8 at the top is set as a magnifying glass, so that the observable root system image can be magnified. When observing the root system of the tobacco seedlings, the root system can be seen clearly without the eyes being close to the observation lens 8, avoiding the need to lean forward and align the eyes with the observation lens 8 during the root system observation process.
