The design uses the re-engineering of pavilions combined with new technologies, to provide water to rice by using solar energy and the temperature difference between day and night in desert areas.The economy in Northwest China is deficient, and the land desertification in this area is serious. It is very important to manage and develop this area, and agriculture is an efficient way.We build this pavilion by using zeolite which is easy to get and waste polyethylene and plant straw powder recycled board and its production process.The new technology cleverly uses the heat generated when the water phase changes. A solar absorber panel on top of the box-shaped system collects the heat from the sun’s light, which then heats the zeolite, releasing the moisture it had absorbed the previous night. The steam condenses on the collector plates – a process that also releases heat. The collector plate is the copper sheet directly above and in contact with the second zeolite layer, the heat of condensation in it is used to release the steam of the next layer, the water droplets collected from each layer can be collected into a conduit and flow into the middle collector In the device, water is supplied to the paddy field through the conduit in the rod.
