Film full-open type arch-shaped film greenhouse

Abstract

The invention discloses a film full-open type arch-shaped film greenhouse. The width of a skylight can be freely opened according to the temperature requirement of the greenhouse under the conditions of not changing a physical structure of an existing greenhouse, not increasing too much cost, not causing a complicated structure and not excessively repairing and maintaining, even the whole greenhouse film can be completely rolled to the vault in sunny days in summer, high-temperature harm is not caused, and the illumination condition of crops in the greenhouse can be improved. Meanwhile, the service life of the film can be prolonged, the land utilization rate is increased, typhoon, strong wind and snow damage is resisted, and secondary salinization damage is reduced.

Description

technical field

[0001] The invention relates to the technical field of modern agricultural facilities, in particular to a film full-open arch film greenhouse. Background technique

[0002] Plastic greenhouses are the fastest growing and largest agricultural production facilities in the world. They have multiple functions such as heat preservation and rain shelter, and play an active role in increasing production, improving quality, and adjusting production periods. They are the development direction of modern agriculture. However, there are three defects: 1) the temperature is too high in summer, and it is difficult to cool down, which has an adverse effect on the growth of crops; 2) the aging of plastic films and the adhesion of dust lead to a decrease in light transmittance, which affects plant growth and development, and affects yield and production. quality; 3) In order to improve the ventilation effect, the area of ​​the plastic greenhouse is controlled at 2000m 2 Next...
