Agricultural greenhouse plastic film mulching construction method

Abstract

The invention provides an agricultural greenhouse plastic film mulching construction method. Mulching construction of an agricultural greenhouse plastic film is completed through cooperation of movingplatforms, arc sliding rails, a laying device and an unreeling device. By means of the agricultural greenhouse plastic film mulching construction method, the problems, which mainly exist in a processof manual replacement of a greenhouse film, that the greenhouse film is generally liable to be scratched by a greenhouse skeleton during replacement, consequently the greenhouse film is very liable to be torn, thus the greenhouse film laying efficiency is affected, when the greenhouse film is laid on the greenhouse skeleton manually, due to different height of the greenhouse skeleton, a worker needs to assist other climbing facilities so that the greenhouse film can be made to stride over the highest position of the greenhouse skeleton and be laid on the greenhouse skeleton, tensioning of thegreenhouse film is hard to maintain when the greenhouse film is laid manually, consequently the greenhouse film is loose as a whole after being laid, thus light transmittance and a heat preservationeffect of the plastic film are severely affected, and the like can be solved.

Description

technical field [0001] The invention relates to the technical field of greenhouse construction, in particular to a plastic film covering construction method for agricultural greenhouses. Background technique [0002] Greenhouse plastic film refers to a special plastic film used for facility agricultural production and construction. Its light transmittance, heat preservation, tensile and aging resistance are better than ordinary agricultural film. It is of great significance to the growth of greenhouse crops, increasing production and increasing income. [0003] The plastic film of the greenhouse has a certain service life. After reaching a certain service life, its light transmittance becomes low, and it is easy to cause damage and affect the temperature in the shed, resulting in a decrease in the growth rate of the plants in the shed. Therefore, the plastic film of the greenhouse needs to be replaced regularly. , Usually, the replacement of the plastic film in the greenhou...

Problems solved by technology

[0003] The plastic film of the greenhouse has a certain service life. After reaching a certain service life, its light transmittance becomes low, and it is easy to cause damage and affect the temperature in the shed, resulting in a decrease in the growth rate of the plants in the shed. Therefore, the plastic film of the greenhouse needs to be replaced regularly. , Usually, the replacement of the plastic film in the greenhouse is manual operation. The manual replacement operation mainly has the following problems: a: The replacement of the greenhouse film is usually easy to scratch with the framework of the greenhouse, which can easily cause the tear of the greenhouse film and affect the efficiency of the greenhouse film laying; b: When artificially laying the greenhouse film on the greenhouse skeleton, due to the inconsistent height of the greenhouse skeleton, workers need to assist other climbing facilities to lay the greenhouse film across the highest point of the greenhouse skeleton on the greenhouse skeleton; c: It is difficult to maintain the artificial laying of the greenhouse film The tension of the greenhouse film causes the overall looseness of the greenhouse film after laying, which seriously affects the light transmittance and thermal insulation effect of the plastic film
