Outside shading System.
Material: circular knitting silk curtains Function: The external shading system can improve the greenhouse environment by adjusting the light intensity.When the greenhouse is exposed to strong sunlight, the use of a shading screen, so that most of the sunlight can not be directly exposed to the greenhouse, to avoid burning crops after the strong light.
Inside Shading System.
Material: aluminum foil and polyester woven. Function: reduce temperature, save energy, prevent lower condensation
Irrigation System
1.Irrigation and fertilization water treatment system with reasonable design improves absorption function of crops toward fertilizer. Meanwhile, it improves crop quality. 2. It is especially suitable for the area with poor water quality and crop greenhouse which has high requirements for planting water quality. 3. The advanced treatment process is combined with greenhouse production process effectively. The irrigation system divided into two kinds of main type: 1.Mobile sprinkler irrigation  2.Fixed sprinkler irrigation
