[0002] Vegetable hydroponics is a method of growing plants in water without soil. Patent document: CN210406551 U proposes a water circulation structure for a multi-layer hydroponic device. Through a water pump, water flows into the tee and the column in turn, enters the planting trough from the water inlet, and when the water level reaches the drain outlet, the water flows out from the drain outlet and flows back to the water tank from the column and the tee in turn. The water inlet pipe and the drain pipe that originally needed to be installed are cleverly omitted and replaced by hollow columns, which reduces costs and is practical and beautiful. The column and the installation through hole are connected by plug-in, which is easy to install and does not require nails or buckles. The problem with the above scheme is that the water in the hydroponic system of vegetables evaporates more obviously during the hydroponic process, which leads to an increase in the concentration of the nutrient solution, thereby causing a certain degree of adverse effect on plant growth. At the same time, vegetables are easily attacked by insects or pests, increasing the impact of pests and diseases on plant health. Utility Model Content
