Furthermore, the relationship between the seed germination net and the height adjusting iron wires is that the height adjusting iron wires are fixed at four corners of the seed germination net respectively, and the hardness of the iron wires is determined according to the size of the seedlings. In order to ensure the stability of the structure, the height adjusting iron wires can not be less than 4, and the length of the iron wires is 1cm-2cm greater than the height of the water culture box.

Furthermore, the method for fixing the seed germination net in the water culture box comprises the steps of combining and fixing four opposite angles of the seed germination net and the height adjusting iron wire together to form a movable node, then placing the seed germination net in the water culture box, enabling the seed germination net to be tightly attached to the liquid level, enabling the four height adjusting iron wires to be perpendicular to the bottom of the water culture box, adjusting the height adjusting iron wires according to the distance between the seed germination net and the upper edge of the water culture box, twisting the grown iron wires to form a hook, and hanging the hook on the edge of the opening of the water culture box.

Furthermore, the height adjustment method of the seed germination net comprises the steps of simultaneously pulling up or pulling down four iron wires perpendicular to the germination net, bending the iron wires to form hooks, hanging the hooks at the edge of the opening of the water culture box, fixing the hooks at the opening of the water culture box, and enabling seeds and root systems to be kept in contact with the water surface by adjusting the height of the seed germination net.

The utility model has the advantages of, the hydroponic device that this application provided:

(1) the volume of the root system can be dynamically measured while the volume of the absorbed liquid can be visually and dynamically measured.

(2) The seed germination and rooting test is completed by one device, the root system is not damaged in the measurement, the design is novel, the structure is reasonable, and the operation is labor-saving, time-saving and labor-saving.

(3) When the seeds germinate, the seeds can be kept moist, the root system can be kept fully immersed in liquid all the time during the growth of the root system, and the condition that the plant dies due to water shortage can not occur.
