Description

Technical Field

[0001] The invention relates to the technical field of facility agriculture, and in particular to a greenhouse cultivation system. Background Art

[0002] In greenhouse cultivation, when sunlight shines on the crops, ground, soil and greenhouse structures in the greenhouse, the heat will be released into the air, causing the temperature in the greenhouse to rise. At present, the cooling devices of greenhouse cultivation systems are mainly sunshade curtains, wet curtains or fans.

[0003] Among them, when the sunshade is opened, the sunlight shining into the greenhouse will be reduced. However, opening the sunshade to block out light will seriously reduce the photosynthesis of crops in the greenhouse, affecting crop growth. When the wet curtain and the fan are turned on, they will take away the heat in the greenhouse, thereby achieving the purpose of lowering the temperature in the greenhouse. However, the cooling of wet curtains and fans is only applicable when the outdoor temperature is below 35°C. When there is severe high temperature weather above 37°C in summer, wet curtains and fans can no longer provide crops with a suitable growth environment temperature.

[0004] Therefore, most existing conventional greenhouse facilities are not suitable for large-scale high-level planting production activities in summer, and can only carry out disinfection operations such as high-temperature greenhouse sealing, which seriously restricts the production efficiency of greenhouse facilities.

[0005] Therefore, how to solve the heat dissipation problem of crop growth space under high temperature environment in summer has become a difficult problem that needs to be solved urgently. Summary of the invention
