Greenhouse structure convenient to change greenhouse film
Technical Field
The invention relates to the technical field of agricultural production, in particular to a greenhouse structure convenient for replacing a greenhouse film.
Background
The greenhouse film is a special plastic film for agricultural production and construction, and has better performances in light transmittance, heat preservation, tensile strength and aging resistance than common agricultural films. Has important significance for the growth, the yield increase and the income increase of greenhouse crops. However, the greenhouse film has a certain service life, and after the greenhouse film reaches the certain service life, the light transmittance of the greenhouse film becomes low, the greenhouse film is easily damaged, the temperature in the greenhouse is influenced, the growth speed of plants in the greenhouse is reduced, and therefore the greenhouse film needs to be replaced regularly.
However, most of the existing greenhouse films are replaced by manually spreading and paving rolled greenhouse films on a shed frame; the greenhouse film is punched and fixed on the shed frame by adopting a rope, so that the heat insulation performance of the greenhouse film is reduced and the wind resistance borne by the greenhouse film is reduced; moreover, the heights of the greenhouses are different according to different requirements of planting crops, and the greenhouse film is difficult to cover on the greenhouse frame for some high greenhouses manually, so that the greenhouse film is difficult to replace quickly by manual work.
