Film greenhouse capable of opening ceiling

Abstract

The invention discloses a film greenhouse capable of opening a ceiling. The film greenhouse comprises a top frame, a framework and braces, wherein a film cloth is paved on an upper wall of the top frame; the framework is fixed under the top frame; the two ends of the top frame are fixedly connected with the two ends of the framework; same film cloths are paved on the two parts of the top frame; drawing wires are inserted into the braces; pull rings are connected with the other ends of the drawing wires. In the film greenhouse capable of opening the ceiling disclosed by the invention, the drawing wires are connected with the two sides of the film cloths; under a sunny condition, the film cloths can be pulled down in the manner of pulling the drawing wires on the two sides, so that the vegetables in the greenhouse can be in full contact with sunlight; on rainy days, the film cloths can be pulled up and closed in the manner of pulling the middle drawing wire, so that the function of keeping out wind and rain can be achieved; fluorescent layers are wrapped on the braces, so that the braces can illuminate under the condition of power outage and people can more conveniently observe the production condition of the vegetables at night.

Description

technical field [0001] The invention relates to the technical field of vegetable greenhouses, in particular to a film greenhouse with an openable ceiling. Background technique [0002] With the emergence of high molecular polymers - polyvinyl chloride and polyethylene, plastic films are widely used in agriculture. In the early 1950s, Japan, European and American countries successfully applied greenhouse films to cover hotbeds, and then covered small sheds and greenhouses with good results. my country introduced polyvinyl chloride agricultural film in the autumn of 1955. It was first used to cover vegetables in small sheds in Beijing, and achieved the effect of early maturity and increased production. The greenhouse was originally a special equipment for vegetable production. With the development of production, the application of greenhouses has become more and more extensive. At present, greenhouses have been used for potted flower and cut flower cultivation; fruit tree pr...

Problems solved by technology

[0003] However, in sunny weather, it is difficult to open the top cloth of the existing greenhouses, and the setting of the top cloth also blocks the transmission of sunlight, so that the vegetables under the greenhouse cannot perform photosynthesis well. In the case of power failure, It is also very inconvenient to observe the vegetables in the greenhouse
