Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work fall within the scope of protection of the present application.

[0042] Embodiment 1

[0043] Please refer to Figures 1-11 A seed germination capacity detection device facilitating image acquisition includes a detection tank 1, an image acquisition part 2 and a culture dish groove 3. An openable door (not shown in the figure) is arranged on the front side of the detection tank 1 during use, and then a temperature and humidity detection and control device is installed in the detection tank 1. This part of the device is prior art and will not be described in detail in this application. An image taking camera 21 is arranged on the image acquisition part 2, which is used to take images of seed germination. The culture dish groove 3 is used to place soil required for seed germination.

[0044] In the technical solution, the upward detachable spiral water and fertilizer tank 4 is arranged in the detection box 1, that is, the whole spiral water and fertilizer tank 4 can be separated from the detection box 1 when it is lifted upward. The spiral water and fertilizer tank 4 is rotationally connected with the detection box 1, and a plurality of petri dish grooves 3 are arranged on the spiral surface of the spiral water and fertilizer tank 4 and uniformly distributed along the spiral direction, so that the petri dish grooves 3 on the spiral water and fertilizer tank 4 can revolve when the spiral water and fertilizer tank 4 rotates. The bottom of the petri dish groove 3 is connected with the inner cavity of the spiral water and fertilizer tank 4 through the water suction part 31 and is rotationally and vertically movably connected with the spiral water and fertilizer tank 4, that is, the spiral water and fertilizer tank 4 stores water and fertilizer, and then the water and fertilizer required for germination is supplied to each petri dish groove 3 through the water suction part 31, wherein the spiral water and fertilizer tank 4 has the function of supplying equal amount of liquid to each petri dish groove 3, that is, each petri dish groove 3 obtains equal amount of water and fertilizer, so that all the petri dish grooves 3 are in an equal supply environment.

[0045] Specifically, the spiral water and fertilizer tank 4 comprises a middle pipe 41, a spiral pipe 42, a gate plate 43 and a transmission shaft 44, the spiral pipe 42 is fixedly sleeved outside the middle pipe 41, the cross section of the spiral pipe 42 is approximately rectangular, the gate plate 43 is slidably connected to the upper and lower sides of the spiral tank body of the spiral pipe 42 and is close to the downstream side of the water suction part 31, and in specific implementation, a plug hole in sealing connection with the gate plate 43 can be formed on the upper and lower sides of the spiral tank body, so that all the gate plates 43 divide the spiral pipe 42 into a plurality of liquid storage cavities which are spirally arranged upward and downward and are used for storing water and fertilizer, wherein the gate plate 43 is provided with an overflow port 431 close to the top on one side, and the overflow port 431 is located in the spiral pipe 42 and close to the top, so that each liquid storage cavity is in an equal storage state of water and fertilizer liquid due to the overflow, and a water and fertilizer liquid transmission pipe can be installed on the top of the spiral pipe 42 during use. The transmission shaft 44 is sleeved in the middle pipe 41 and vertically movably connected with the middle pipe 41, the outer periphery of the transmission shaft 44 is fixedly connected with the link rod 441 which is fixedly connected with the top of the gate plate 43, and the transmission shaft 44 controls the synchronous upward and downward movement of all the gate plates 43, and has the functions of controlling the amount of water and fertilizer liquid stored in the liquid storage cavities and plugging the liquid storage cavities.

[0046] The water absorption part 31 comprises an upper tube 311, a lower tube 312 and a water absorption strip 313. The water absorption strip 313 is a tubular structure with water absorption cotton inside. The water absorption strip 313 is sleeved in the upper tube 311.

The top of the upper tube 311 is fixedly connected with the bottom of the culture dish groove 3. The spiral surface of the spiral tube 42 is fixedly connected with a connecting tube 421 sleeved outside the lower tube 312. The bottom of the connecting tube 421 is close to the bottom wall in the liquid storage cavity. The connecting tube 421 and the lower tube 312 are slidingly connected. The bottom of the connecting tube 421 is bonded with a blocking valve 4211. When the upper tube 311 rotates, the culture dish groove 3 can rotate, so that all seeds can be uniformly illuminated. When the lower tube 312 moves up and down, the water absorption strip 313 can enter and exit the liquid storage cavity. The blocking valve 4211 is a silicone sheet structure with a circular hole in the middle. The diameter of the circular hole is smaller than the outer diameter of the water absorption strip 313. When the bottom of the water absorption strip 313 is above the blocking valve 4211, the blocking valve 4211 will approximately block the water and fertilizer in the liquid storage cavity from being transmitted to the corresponding culture dish groove 3 through the water absorption strip 313. This arrangement can further improve the uniformity of the water and fertilizer solution obtained by each culture dish groove 3. Specifically, when the water and fertilizer solution in the spiral tube 42 flows, it fills the spiral tube 42.

When in use, the lower tube 312 moves downward to penetrate the blocking valve 4211. When it moves upward to leave the blocking valve 4211, the blocking valve 4211 is approximately in a closed state, so that the lower tube 312 is approximately in a blocking state.

[0047] The outer peripheral wall of the lower tube 312 is fixedly connected with the top of the adjacent gate plate 43 through the arm plate 3121. In specific implementation, a connecting shaft is welded on the top of the gate plate 43 and fixedly connected with the arm plate 3121.
