maintenance of film greenhouse
The film greenhouse is not a traditional single greenhouse, but a large greenhouse connected by a single greenhouse. The original independent greenhouse is connected with the original single-room greenhouse, the design is reasonable, the insulation area is increased, and the performance of the greenhouse is improved. The greater the proportion of heat preservation, the better the heat preservation performance of the greenhouse.

The maintenance of multi-span greenhouse buildings mainly involves the maintenance of skeleton structure. For the covering material, the main purpose is to improve its damage resistance, aging resistance, wind and sun protection, to achieve the purpose of transparent heat insulation. Therefore, reinforcement measures should be taken, and if leaks are found, they should be repaired in time. If the greenhouse is used for a long time, the film will be stained with dust, greatly reducing the light transmittance. Therefore, the membrane of the multi-membrane greenhouse should be cleaned regularly according to the pollution of each area to maintain the light transmission rate. Especially for plastic greenhouses in winter, this work is very important in early spring when the temperature is lower. The cleaning time of the film should be in sunny noon and high temperature in the afternoon.
When cleaning the film layer of a multi-span film greenhouse, you can use a homemade long soft brush and use a hose to spray pressurized water to the top of the greenhouse. In a section clean, you can build a triangular ladder or scaffolding. During the use of the greenhouse, if the film becomes loose, it will flutter up and down under the influence of the wind, and it is easy to damage the film. If the film is found to be loose, it should be tightened and installed in time. When used for a long time, the film rupture is inevitable, but it should be repaired in time. Repair methods can use special plastic patches or cover specific areas with a new film.
