[0028] Please refer to Figure 1 , Figure 1 It is a structure diagram of the wheat seedling stage test different organ sampling device in the embodiment of the utility model, a wheat seedling stage test different organ sampling device, comprising a hydroponic mechanism 1, which comprises a hydroponic shell 11, a nutrient cavity 12 is formed in the hydroponic shell 11, an outer edge plate 13 is arranged on the inner wall of the hydroponic shell 11, and notches 14 are symmetrically formed on the two sides of the hydroponic shell 11.

[0029] A cultivation disc 2 is detachably arranged on the outer edge plate 13, a plurality of cultivation holes 21 are formed in the cultivation disc 2, a root growth tube 22 is threadedly connected below the cultivation disc 2 and below any one of the cultivation holes 21, a planting basket 23 is placed in the cultivation hole 21, and positioning blocks 24 corresponding to the notches 14 are arranged on the two sides of the cultivation disc 2.

[0030] An adjusting mechanism 3 comprises a driving end 31 and a vertical rod 32; the driving end 31 is used to drive the cultivation disc 2 to slide on the vertical rod 32 through the positioning blocks 24, and to make the cultivation disc 2 away from or close to the hydroponic shell 11.

[0031] In the embodiment, the nutrient cavity 12 is formed in the hydroponic shell 11, liquid can be conveniently added in the nutrient cavity 12, the outer edge plate 13 is arranged on the inner wall of the hydroponic shell 11, the cultivation disc 2 is conveniently carried, the notches 14 are arranged on the outer wall of the hydroponic shell 11, the integrity of the cultivation disc 2 placed in the hydroponic shell 11 is enhanced, a plurality of cultivation holes 21 are formed in the cultivation disc 2, one wheat is placed in each hole, and the independent growth of the root system can be ensured, the detachable root growth tube 22 is arranged below the cultivation hole 21, the root system can be conveniently observed and sampled, the cultivation disc 2 can be lifted and lowered through the cooperation of the driving end 31 and the vertical rod 32, and therefore subsequent staff can conveniently sample different organs of different height wheat.

[0032] In one of the embodiments, please refer to Figure 1 - Figure 4For the convenience of filling the nutrient solution into the nutrient cavity 12, the water culture shell 11 is provided with water inlet port 15 and water outlet port 16 on both sides, the water inlet port 15 and the water outlet port 16 are communicated with the nutrient cavity 12 uniformly, and the water inlet port 15 and the water outlet port 16 are provided with regulating valves.

[0033] In the embodiment, the nutrient cavity 12 can be filled with nutrient solution through the water inlet port 15, and the water outlet port is arranged to facilitate regular replacement of the nutrient solution. The application adopts a bottom water supply mode, and the wheat root stems are soaked from bottom to top in the nutrient cavity 12, instead of being directly watered from the top. The main purpose is to simulate the natural germination conditions and avoid damage to the wheat. When the wheat germinates in natural soil, the water penetrates from the bottom to the top through the soil capillary action. The liquid level of the nutrient cavity 12 of the device rises to simulate this process, so that the water uniformly soaks the wheat root base and avoids direct flushing from the top. The water flow impact may cause damage to the wheat. When the bottom water supply is adopted, the upper part of the planting basket 23 remains breathable to ensure the oxygen exchange required for the respiration of the wheat. If the top is watered, a water film may be formed to block the pores and cause oxygen deficiency.

[0034] In one of the embodiments, please refer to Figure 1 Figure 4 For the convenience of protecting the wheat root stems, the inside of any one of the cultivation holes 21 is provided with an annular block 211, the annular block 211 carries a planting basket 23, and the planting basket 23 is arranged with a planting sponge 231.

[0035] In the embodiment, the planting basket 23 and the planting sponge 231 are used to fix the wheat stem base, and the stem and leaf part is exposed to the air and physically isolated from the root system area. The planting sponge 231 is arranged to tightly wrap the wheat stem base by the elasticity of the sponge, prevent the seedling period from appearing lodging or displacement, and avoid mechanical damage. The planting sponge 231 can be applied to wheat seedling stems of different thicknesses, especially the fine wheat stems in the seedling period, such as the diameter of 1-2 mm. The planting sponge 231 provides uniform support, and the pore structure of the sponge can maintain moderate humidity and allow oxygen exchange to prevent the root system from being oxygen-deficient. When the adjusting mechanism 3 lifts the cultivation disc 2, the sponge can alleviate the impact of water level fluctuation on the root system. When transplanting, the wheat seeds or seedlings can be directly inserted into the wet sponge to be fixed, without complex operation. When sampling, the plants can be easily pulled out, and the sponge can be reused or replaced to avoid damage to the root system.

[0036] In one of the embodiments, please refer to Figure 1 Figure 4 ​​For the convenience of sampling and observing the root system, a threaded groove 212 is arranged below the lower end of the culture disc 2 and below any one of the culture holes 21, and a root growth tube 22 is threadedly connected in the threaded groove 212. The root growth tube 22 is a transparent tube body. The front surface of the water culture shell 11 is also provided with a visible end 4 for observing the nutrient cavity 12. The visible end 4 includes a visible window 42. The front surface of the water culture shell 11 is provided with a recess 41 in which the visible window 42 is arranged. A shutter 43 is detachably connected in the recess 41 through a suction accessory 44. The recess 41 is provided with an extension groove 411 on each side. The shutter 43 is provided with an extension plate 431 on each side which is attached to the extension groove 411. The suction accessory 44 includes a magnet block 441 and an iron sheet 442. The magnet block 441 is attached to the extension plate 431, and the iron sheet 442 is attached to the extension groove 411. The front surface of the shutter 43 is also provided with a protrusion.

[0037] In the embodiment, the transparent root growth tube 22 is threadedly connected below the culture hole 21 to facilitate cooperation with the visible window 42. The visible window 42 is a transparent plate body to facilitate the staff to observe the inside of the nutrient cavity 12. When the staff finds that the nutrient solution appears turbid, precipitate or bubbles, the staff can replace the nutrient solution in time. The transparent tube material is also used to observe the root growth. The root system can be selectively shaded by wrapping black cloth to study the effect of light on the development of the root system. The specific areas of the root system, such as the root tip meristem and lateral root initiation site, can be determined through the transparent tube material to achieve precise cutting and sampling and avoid sample waste. The recess 41 is arranged on the surface of the water culture shell 11, and the extension groove 411 is arranged on each side of the recess 41 to facilitate cooperation with the extension plate 431 on each side of the shutter 43 so that the extension plate 431 is attached to the extension groove 411. The magnet block 441 is arranged on the extension plate 431 to be adsorbed on the iron sheet 442 on the inner wall of the extension groove 411 to enhance the tightness between the shutter 43 and the water culture shell 11.
