[0027] Among them, a foam board 103 is provided at the top of each of the hydroponic trays 101, and a limit block 104 for supporting the foam board 103 is installed on both sides of each of the hydroponic trays 101. A plurality of sockets 105 are provided on the top of the foam board 103, and a hydroponic bucket 106 is plugged into each of the plurality of sockets 105. A plurality of openings are provided on the outside of the hydroponic bucket 106, and a liquid injection port 6 is provided on one side of the top of the foam board 103.

[0028] During soilless test cultivation of plants, pour an appropriate amount of nutrient solution into the hydroponic tray 101, then place the foam board 103 into the hydroponic tray 101, support the foam board 103 with the limit blocks 104 on both sides of the hydroponic tray 101, and insert the hydroponic bucket 106 into the hydroponic tray 101 through the socket 105, so that the hydroponic bucket 106 can contact the nutrient solution, and the nutrient solution can enter the hydroponic bucket 106 from the opening. At this time, plant seedlings can be placed in the hydroponic bucket 106. The seedlings can absorb nutrients and grow by contacting the nutrient solution, and then be cultivated and grown in the hydroponic tray 101, which is convenient for staff to record plant growth parameters, such as plant height, leaf area, biomass, flowering and fruiting, etc., and draw experimental conclusions after analyzing the data.

[0029] Among them, the left frame plate 2 is fixedly installed on one side of the outer end of the test cultivation frame 1, and three fixed plates a201 are fixedly installed on the inner side of the left frame plate 2. The tops of the three fixed plates a201 are fixed with electric push rods 202 by bolts, and the tops of the electric push rods 202 are installed with mounting blocks 203. A lifting plate 204 is fixedly installed on one side of the outer ends of multiple hydroponic trays 101 by bolts. The lifting plate 204 and the mounting blocks 203 are fixed by bolts. During the cultivation and growth process of plants on the hydroponic trays 101, the plant stems gradually grow taller and the leaves grow thicker. The more luxuriant the plant is, the more tightly it fits with the hydroponic tray 101 on the upper layer. The electric push rod 202 is started to push the lifting plate 204 to move upward. The lifting plate 204 drives the hydroponic tray 101 to slide upward in the test cultivation rack 1 to adjust its position, so that the space between the hydroponic trays 101 becomes larger, preventing the plant from touching the bottom of the hydroponic tray 101 to avoid affecting the cultivation and growth of the plant. It is also convenient for the staff to open the leaves to observe whether there are diseases and insects on the leaves of the plant, and to carry out pest control on the plants in time to avoid poor plant growth.

[0030] Among them, a right frame plate 3 is fixedly installed on the other side of the outer end of the test cultivation frame 1, and three fixed plates b301 are fixedly installed on the inner side of the right frame plate 3. The tops of the three fixed plates b301 are fixedly installed with support rods 302. A lifting plate 303 is fixedly installed on the other side of the outer ends of multiple hydroponic trays 101 by bolts. A sliding sleeve 304 is installed on the lifting plate 303 to be slidably connected to the support rod 302. When the lifting plate 303 is pushed to drive the hydroponic tray 101 to move upward to adjust its position, the lifting plate 303 on the other side of the hydroponic tray 101 is subjected to force and moves synchronously with the support rod 302 through the sliding sleeve 304. During the movement of the hydroponic tray 101, it can ensure that the hydroponic tray 101 has a stable supporting force, thereby ensuring that the hydroponic tray 101 is stably placed and used.

[0031] Among them, a drain pipe 4 is installed on the outside of multiple hydroponic trays 101, and a sealing cover 401 is threadedly connected to the outer end of the drain pipe 4. After the nutrients in the nutrient solution inside the hydroponic tray 101 are absorbed by the plants after a period of time, the sealing cover 401 can be loosened and opened, and a container is placed on the outside of the drain pipe 4. The nutrient solution inside the hydroponic tray 101 is discharged into the container through the drain pipe 4 for collection. After the nutrient solution is drained, the foam board 103 is taken out, and the dirt inside the hydroponic tray 101 is cleaned with clean water to prevent the dirt from breeding bacteria, and then the foam board 103 is placed inside the hydroponic tray 101.

[0032] Among them, a liquid storage tank 5 is fixedly installed on the outer end of the left frame 2, and a liquid pump 501 is installed on one side of the bottom of the liquid storage tank 5. A liquid extraction pipe is installed between the liquid pump 501 and the liquid storage tank 5, and a delivery hose 502 is installed on the top of the liquid pump 501. A control valve 503 is installed on the top of the delivery hose 502. After the inside of the hydroponic tray 101 is cleaned, the liquid pump 501 is started to work, and the liquid pump 501 generates negative pressure suction in the liquid extraction pipe to extract the nutrient solution stored in the liquid storage tank 5 and discharge it into the delivery hose 502 through the liquid pump 501. One end of the delivery hose 502 is inserted into the liquid injection port 6, and the control valve 503 is opened to allow the nutrient solution to be discharged from the delivery hose 502 into the hydroponic tray 101, and the hydroponic tray 101 is injected with clean nutrient solution. The length of the delivery hose 502 is five meters, which is long enough to add nutrient solution to multiple hydroponic trays 101 at different heights.

[0033] A control panel is fixedly installed on the back of the liquid storage tank 5. The liquid pump 501 and the electric push rod 202 are connected to the control panel through wires, and the control panel is externally powered, so that the control panel, the liquid pump 501 and the electric push rod 202 can be powered on and used normally, and the start and stop of the liquid pump 501 and the electric push rod 202 can be controlled through the control panel. The control procedures involved in the present invention can be implemented by those skilled in the art according to the same or similar principles in the prior art. This part is not the innovation of the present invention.

[0034] Among them, a partition 504 is fixedly installed between the liquid storage tank 5 and the left frame plate 2, a through hole is opened on the top of the partition 504, and a baffle 505 is fixedly installed on one side of the top of the partition 504. The two ends of the baffle 505 are tightly fitted with the left frame plate 2 and the liquid storage tank 5. When the delivery hose 502 is in use, the delivery hose 502 passes through the through hole and is located on the top of the partition 504. After adding nutrient solution to the hydroponic tray 101, the delivery hose 502 can be rolled up and placed on the partition 504, and a limiting cavity is formed between the baffle 505, the left frame plate 2 and the liquid storage tank 5 to store and place the delivery hose 502, so as to avoid the delivery hose 502 being scattered on the ground and affecting the use of the test cultivation rack 1.

[0035] Working principle:

[0036] During soilless test cultivation of plants, pour an appropriate amount of nutrient solution into the hydroponic tray 101, then place the foam board 103 into the hydroponic tray 101, support the foam board 103 with the limit blocks 104 on both sides of the hydroponic tray 101, and insert the hydroponic bucket 106 into the hydroponic tray 101 through the socket 105, so that the hydroponic bucket 106 can contact the nutrient solution, and the nutrient solution can enter the hydroponic bucket 106 from the opening. At this time, plant seedlings can be placed in the hydroponic bucket 106. The seedlings can absorb nutrients and grow by contacting the nutrient solution, and then be cultivated and grown in the hydroponic tray 101, which is convenient for staff to record plant growth parameters, such as plant height, leaf area, biomass, flowering and fruiting, etc., and draw experimental conclusions after analyzing the data.

[0037] During the cultivation and growth of plants on the hydroponic tray 101, the stems of the plants gradually grow taller and the leaves become more and more lush. When the plants grow lushly and fit closely together with the hydroponic tray 101 on the upper layer, the electric push rod 202 is started to push the lifting plate 204 to move upward. The lifting plate 204 drives the hydroponic tray 101 to slide upward in the test cultivation rack 1 to adjust its position, so that the space between the hydroponic trays 101 becomes larger, preventing the plants from touching the bottom of the hydroponic tray 101, avoiding affecting the cultivation and growth of the plants, and making it convenient for the staff to open the leaves to observe whether there are diseases and insects on the leaves, so that the plants can be dewormed in time to avoid poor plant growth.

[0038] After the nutrients in the nutrient solution inside the hydroponic tray 101 have been absorbed by the plants for a period of time, the sealing cover 401 can be loosened and opened, and a container can be placed on the outside of the drain pipe 4 to discharge the nutrient solution inside the hydroponic tray 101 into the container for collection through the drain pipe 4. After the nutrient solution is drained, the foam board 103 is taken out, and the dirt inside the hydroponic tray 101 is cleaned with clean water to prevent the dirt from breeding bacteria. The foam board 103 is then placed inside the hydroponic tray 101, and the liquid pump 501 is started. The liquid pump 501 generates negative pressure suction in the liquid extraction pipe to extract the nutrient solution stored in the liquid storage tank 5 and discharge it into the delivery hose 502 through the liquid pump 501. One end of the delivery hose 502 is inserted into the liquid injection port 6, and the control valve 503 is opened to allow the nutrient solution to be discharged from the delivery hose 502 into the hydroponic tray 101, and the hydroponic tray 101 is injected with clean nutrient solution.
