[0013] The beneficial effects of the present utility model are as follows:

[0014] In the present utility model, the soil-fixing hollow seat is arranged to cover the land and form an enclosed state by entering the soil through its outer wall on the upper side. The heat preservation transparent cover can be installed and used by means of the clamping groove, thereby forming a plant cultivation environment.

The bottom of the water storage tank 3 is connected to a rotating disk 6 with an electric control valve through a water delivery pipe. The top of the rotating disk 6 is rotatably connected to a two-way spray pipe 7 through a bearing. A clamping groove 8 is provided at the top of the soil-fixing hollow seat 1. A heat preservation transparent cover 9 is clamped to the inner wall of the clamping groove 8. A groove is provided on the rear side of the inner wall of the soil-fixing hollow seat 1. A temperature sensor 10 and a humidity sensor 11 are fixedly installed on the inner wall of the groove. A waterproof baffle 12 is fixedly installed on the inner wall of the soil-fixing hollow seat 1, and the waterproof baffle 12 is located directly above the temperature sensor 10 and the humidity sensor 11. An electric cylinder 13 is fixedly installed inside the waterproof baffle 12. A soil humidity sensor 14 is fixedly installed at the output end of the electric cylinder 13.

[0027] Specifically, as Figures 1-6 shown, a ventilation box 15 with a filter screen is fixedly connected to the right side of the soil-fixing hollow seat 1. A blowing fan 25 is fixedly installed on the inner wall of the ventilation box 15. Operating the blowing fan 25 speeds up the air flow in the soil-fixing hollow seat 1.

[0028] Furthermore, a temporary placement frame 17 is fixedly connected to the top of the water storage tank 3. The inner wall height of the temporary placement frame 17 is at least 10 cm, and the inner wall of the temporary placement frame 17 is coated with an anti-sticking coating. Cultivated plants can be temporarily placed inside the temporary placement frame 17.

[0029] Specifically, as Figures 1-6As shown in the figure, a temperature control heating plate 16 is fixedly installed on the side of the water storage tank 3, and the output end of the temperature control heating plate 16 is located inside the water storage tank 3. The operation of the temperature control heating plate 16 can be used to control and change the water temperature inside the water storage tank 3, so as to control the temperature when spraying water to the cultivated plant space later.

[0030] Example 2 Please refer to Figures 1-6 , the difference between this embodiment and Embodiment 1 is that both the rear side and the front side of the adjustment restraint frame 4 are fixed plates. The rear fixed plate is rotatably connected to an adjustment screw 18 through a bearing. A threaded sleeve plate 19 is threadedly connected to the surface of the adjustment screw 18. A limiting component is connected to the rear side of the threaded sleeve plate 19. The front side of the threaded sleeve plate 19 is fixedly connected to a moving restraint plate 20, and the front side of the moving restraint plate 20 is slidably connected to the inner wall of the front fixed plate. A fixed restraint plate 21 is fixedly connected to the surface of the fixed plate. The limiting component includes a limiting plate 22 and a limiting groove 23. The limiting plate 22 is fixedly connected to the rear side of the threaded sleeve plate 19. The limiting groove 23 is opened on the inner wall of the fixed plate. The inner wall of the limiting groove 23 is slidably connected to the surface of the limiting plate 22. Compression-resistant pads 24 are fixedly connected to the surfaces of both the moving restraint plate 20 and the fixed restraint plate 21. An anti-corrosion coating is applied to the surface of the compression-resistant pads 24. By controlling the rotation of the adjustment screw 18, under the limiting setting of the limiting plate 22 and the limiting groove 23, the movement trajectory of the threaded sleeve plate 19 is limited, so that the rotation of the adjustment screw 18 can drive the threaded sleeve plate 19 to move. The movement of the threaded sleeve plate 19 can drive the moving restraint plate 20 to move, and the movement of the moving restraint plate 20 can change the distance between the fixed restraint plates 21, thereby completing the adjustment of the internal space of the entire adjustment restraint frame 4. Under the action of the compression-resistant pads 24, the degree of outward expansion damage of the roots of agricultural plants to the surrounding area is reduced.

[0031] Working principle of the utility model: During use, the staff can cover the soil with the soil-fixing hollow seat 1, and use the outer circumferential wall of the soil-fixing hollow seat 1 to enter the soil to form a surrounding state. The temperature sensor 10 and humidity sensor 11 at the rear side of the inner wall of the soil-fixing hollow seat 1 are used to sense the air environment of plant cultivation in real time. When it is necessary to monitor the humidity in the soil, the electric cylinder 13 operates to drive the soil humidity sensor 14 to insert into the soil for detecting the humidity in the soil. If the plant cultivation environment is relatively hot, the blowing fan 25 can be operated to accelerate the air flow in the soil-fixing hollow seat 1 to reduce the situation of too high environmental temperature around the plants. If it is necessary to adjust the humidity of the plant cultivation environment, the water storage tank 3 can be connected to the water pipe to supply water to the external filling pipe 5 for watering the soil. The electric control valve on the rotating disk 6 can also be opened, so that the two-way spray pipe 7 can be controlled to rotate and spray under the drive of the water flow. Under the action of the waterproof baffle 12, the sprayed water flow is reduced from splashing onto the humidity sensor 11 and temperature sensor 10, preventing the influence on the detection effect of the temperature sensor 10 and humidity sensor 11 on the temperature and humidity in the air. Since the agricultural plants will gradually grow larger during the production process, but for the convenience of evenly distributing fertilizers for agricultural plants, etc., it is necessary to change and adjust the restraint range of the adjustment restraint frame 4 according to the growth plan of agricultural plants, so as to carry out quantitative feeding of subsequent fertilizers, etc. That is, the rotating adjustment screw 18 is controlled to rotate. Under the limit setting of the limit plate 22 and limit groove 23, the movement track of the threaded sleeve plate 19 is limited, so that the rotation of the adjustment screw 18 can drive the threaded sleeve plate 19 to move. The movement of the threaded sleeve plate 19 can drive the moving restraint plate 20 to move. The movement of the moving restraint plate 20 can change the distance between the fixed restraint plates 21, thereby completing the adjustment of the internal space of the entire adjustment restraint frame 4. Under the action of the compressive cushion plate 24, the degree of outward expansion damage of the roots of agricultural plants to the surrounding is reduced, and the separate detection of the air, soil temperature and humidity in the agricultural plant cultivation environment and the operation of replenishing water and controlling temperature can be realized.

[0032] Although the embodiments of the present utility model have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present utility model. The scope of the present utility model is defined by the appended claims and their equivalents.
