Most of the energy for green plants is obtained from sunlight through photosynthesis. Temperature, humidity, light, and fresh water are the basic needs of plants for survival. Angiosperms have six major organs: roots, stems, leaves, flowers, fruits, and seeds.
- Green plants have the ability of photosynthesis, that is, with the help of light energy and chlorophyll, under the catalysis of enzymes, they use water, inorganic salts and carbon dioxide to perform photosynthesis, release oxygen, and produce organic substances such as glucose for plant utilization.

- the nitrogen in the air storage tank is transported to the inside of the device shell by the air pump, because the pipeline connected to the air pump exhaust port extends to 5 cm above the bottom plate of the device shell, and the density of nitrogen is greater than that of air, so that the air inside the device shell floats up and is discharged through the exhaust pipe connected to the top. At this time, the nitrogen will fill the internal space of the device shell from bottom to top. After the air is discharged, close the manual valve and the air pump to seal the device shell. controller to control the temperature inside the device.
