Detailed Description
When in use, the method comprises the following steps: (1) completely closing the water inlet passage and the air outlet passage by using the water inlet passage plug and the air outlet passage plug; (2) opening a water filling port to fill water into the water storage area until the water storage area is full, stopping filling water and closing the water filling port, wherein the water storage area is in a sealed state and is not influenced by atmospheric pressure; (3) adding water into the water storage area through the holes of the partition plates between the water storage area and the cultivation area until the water storage area is full of water, stopping adding water, and installing a capillary material; (4) the water inlet channel plug and the exhaust channel plug are pulled to the channel openings but not pulled out, so that the water inlet channel and the exhaust channel are ensured to be unblocked; (5) under the capillary action, water in the water storage area is continuously lifted to the bottom of soil in the cultivation area through the capillary material to irrigate the roots of the green plants, so that the water level in the water storage area is slowly reduced; (6) because the capillary material is communicated with the water storage area and the atmosphere, the atmosphere acts on the water storage area, and the water storage area is sealed in a low-pressure environment, so that a certain air pressure difference is formed between the water storage area and the water storage area. When the water level is lower than the exhaust channel opening, air enters the water storage area through the exhaust channel under the action of air pressure difference, the pressure at the upper part of the water storage area is gradually increased, and water in the water storage area is pushed to flow to the water storage area through the water inlet channel, so that the water level in the water storage area is raised; (7) when the water level is higher than the exhaust passage, the air intake is stopped, and then the water in the water storage area is prevented from flowing out, so that the water in the water storage area is slowly flowed out, and the automatic watering can be continued for more than several months as long as the water storage area stores enough water.
Siphon principle and capillary action are used for drawing the water in water storage area to the cultivation district, and after the liquid level in water storage area was less than the exhaust and passes through, under the effect of pressure difference, the air got into the water storage area, and increase water storage area upper portion pressure, and then promoted the water in the water storage area and got into the water storage area, until water storage area liquid level is higher than exhaust passage, exhaust passage closed this moment, and water storage area upper portion forms low pressure space once more. From this time, the automatic irrigation is completed.
