In addition, when the temperature is too high in the daytime, the heat preservation quilt 1 can be only spread without inflating, so that the heat preservation quilt 1 has a shading function, a certain shading and cooling effect is realized, and the damage to plants caused by too strong illumination and too high temperature is avoided.

In actual operation, when the outside temperature is above minus 5 ℃ in summer or winter, the operation and the covering are directly carried out without inflation; normal temperature air can be filled into the mixture at the temperature of minus 5-10 ℃ for heat preservation; under the temperature of minus 10 ℃ or in snowy days, heated air can be filled to increase the heat preservation capability, and the snow can be conveniently melted and discharged on the heat preservation quilt 1.

In addition, the air circulation of the heat preservation quilt 1 can be realized through the closing of the exhaust valve 43 and the linkage of the inflation system, the heating state of the heat preservation quilt 1 is maintained, and the heat preservation and snow melting are facilitated. Parameters can be set according to various situations, and the use efficiency of the heat preservation quilt 1 is improved.

In view of facilitating the maintenance of the heat preservation quilt and related equipment by workers, as shown in fig. 1, a maintenance passage 8 can be further arranged at the end part of the glass greenhouse to facilitate the walking of the workers.

Finally, it should be noted that: the above embodiments are only used to illustrate the technical solution of the present invention, and not to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art will understand that: the technical solutions described in the foregoing embodiments may still be modified, or some technical features may be equivalently replaced; such modifications or substitutions do not depart from the spirit and scope of the technical solutions of the embodiments of the present invention.
