Problems solved by technology
This double-layer structure, the hose inside the double-layer plastic film causes the plastic greenhouse film to be bulky and heavy, making transportation and laying difficult, and the bonding position between the plastic hose and the greenhouse film is very easy to crack, due to the extension of the plastic greenhouse film property, causing the double-layer plastic film to swell into a ball
Therefore, also can't well solve the function of keeping warm in the thermal insulation greenhouse.

The invention discloses a double-layer plastic heat preservation greenhouse film. The interior of the double-layer plastic heat preservation greenhouse film is further provided with a plurality of spacing pieces; the double-layer plastic heat preservation greenhouse film is further provided with a charging valve; a plurality of air chambers are formed between the double-layer plastic heat preservation greenhouse film and the plurality of spacing pieces; and the air chambers are communicated with the charging valve. The double-layer plastic heat preservation greenhouse film is further providedwith a plurality of tying belts; and the tying belts are formed together with the double-layer plastic heat preservation greenhouse film during manufacturing. One end of the double-layer plastic heatpreservation greenhouse film is provided with a left chain, and the other end of the double-layer plastic heat preservation greenhouse film is provided with a right chain; the left chain or the rightchain is further provided with a zip fastener; and the left chain, the right chain and the zip fastener are used for linking and fixing the two adjacent double-layer plastic heat preservation greenhouse films. The double-layer plastic heat preservation greenhouse film has simple structure, is convenient to use, has light weight and low cost and is convenient for transportation and pavement; the greenhouse films are linked simply and conveniently; and the greenhouse film can be installed and reformed on the premise that the conventional heat preservation greenhouse structure is not changed.
Description
Technical field: [0001] The invention relates to the technical field of agricultural plastic greenhouse films, in particular to a double-layer plastic thermal insulation greenhouse film and its application method. Background technique: [0002] Existing greenhouses include plastic greenhouse membranes and steel beams. The steel beams form a full-arc or semi-arc steel frame structure. The plastic greenhouse membrane covers the outer surface of the steel frame structure, and the four sides of the greenhouse membrane are compacted on the ground or buried in the ground. So far, the thermal insulation greenhouse has been formed. However, most of the existing thermal insulation greenhouses use a single-layer plastic greenhouse film. This single-layer plastic greenhouse film has poor thermal insulation effect in winter, and the temperature difference between day and night is large. Facilities, such as stoves or heating channels, etc. In addition, it is also necessary to cover str...
