[0002] Drought stress on corn during the germination period will lead to stunted seedling growth, weak bud vigor, small and short root production, weak seedlings, and low survival rate, which will seriously affect the growth and development of grains and the final yield. Therefore, it is necessary to study the drought resistance of corn varieties.

[0003] When the research site for drought-resistant breeding of corn varieties is a greenhouse, the corn varieties are greatly affected by the outside world.

[0040] Specifically, the mounting frame 4 is fixed to the bottom of the cultivation box 1, and the mounting frame 4 is not set on the side wall of the two adjacent cultivation boxes 1 that are spliced ​​and fitted together. When the two adjacent cultivation boxes 1 are spliced ​​together, the mounting frames 4 thereon are spliced ​​together, and the plug plate 5 can be inserted into the two mounting frames 4 to achieve a limited connection between the two adjacent cultivation boxes 1. At the same time, the cultivation boxes 1 connected together by the plug plate 5 can be indicated to form a corn cultivation device.

[0041] In this embodiment, refer to Figure 3 , Figure 4 , also includes a lighting lamp 6, which is fixed on the top inner wall of the incubator 1.

[0042] The illumination lamp 6 is arranged in the cultivation box 1 to provide the light required for growth. Meanwhile, when studying the drought resistance of corn seeds, the light intensity in multiple cultivation boxes 1 should be nearly the same.

[0043] In this embodiment, refer to Figure 2 , Figure 3 , Figure 4 , and also includes an air inlet pipe 7 and an air outlet pipe 8 connected to the incubator 1 , the air inlet pipe 7 is configured to supply air into the incubator 1 , and the air outlet pipe 8 is configured to exhaust air outside the incubator 1 .

[0044] Specifically, the air inlet pipe 7 and the air outlet pipe 8 cooperate to achieve ventilation in the incubator 1 .

[0045] The air inlet pipe 7 can allow air with a certain temperature to be introduced to maintain the air temperature in the cultivation box 1 suitable for seed cultivation.

[0046] In the above arrangement, two temperature sensors are arranged in the incubator 1 , which are used to obtain the temperature in the covering soil layer 2 and the temperature of the covering soil layer 2 in the incubator 1 , respectively.

[0047] The air inlet pipe 7 can be used to introduce dry air, and the air outlet pipe 8 can discharge the moist air in the incubator 1 to reduce the humidity in the incubator 1. When the humidity in the incubator 1 is greater than the preset humidity, the air inlet pipe 7 and the air outlet pipe 8 are used together to take away the moisture in the incubator 1, so that the humidity in the incubator 1 is maintained within the preset range.

[0048] Furthermore, the air inlet pipe 7 and the air outlet pipe 8 are respectively detachably connected with a blocking cover 10 to achieve controllable blocking of the air inlet pipe 7 and the air outlet pipe 8 .

[0050] Specifically, water is stored in the water tank 9, which is sent into the cultivation box 1 through the first water outlet part or the second water outlet part. The first water outlet part is used to spray water into the cultivation box 1, and the second water outlet part is used to irrigate the covering layer 2. The water supply method into the cultivation box 1 can be selected according to actual test needs.

[0051] Furthermore, the water storage tank 9 is preferably a transparent box with a scale provided on its surface.

The spray plate 11 is arranged in the incubation box 1, and the spray plate 11 corresponds to the surface of the covering layer 2. When the valve on the first water pipe 12 is opened, since the spray plate 11 is located below the water tank 9, the water in the water tank 9 enters the spray plate 11 along the first water pipe 12 under the action of gravity, and is sprayed by the spray plate 11 to simulate rainfall.
