Large shed "rain film" setting skills

According to report, in recent years, in the northern part of Luocheng Street, Shouguang City, Shandong Province, more and more peasant households have built large arch sheds. The most prominent feature of these sheds is that the shed height is 3.5 meters or more, and the space inside the shed is large. Strong buffering capacity against the outside world, and thus, conducive to the production of vegetable crops.

However, due to the shed film of the large arch shed consisting of two large greenhouse membranes and a small shed membrane, the location of the air outlet is at the top of the large arch shed. Even if the tuyere is closed when it rains, there will still be rain due to discharge on the shed roof. The timely pouring into the shed, rain sprinkled on the stems and leaves of vegetables in the shed, easy to spread the disease, has an impact on its growth. Therefore, the rain protection of the large shed is particularly important.

Recently, in an interview with reporters in rural areas, the reporter discovered unexpectedly that Master Li of Dingjialou Village in Luocheng Subdistrict, Shouguang City, had relatively good weatherproof membranes for large arch shelters. The continuous strong rainfall in the previous period had little effect on the cucumbers in the shed.

Master Li's setting technique for large arch shelter film: 1. First prepare a plastic film, the old film can also be used, as long as it is not damaged. The length is the same as the length of the shed, and the width is based on the size of the tuyere. It can be used as long as it can fully protect against rain after being suspended. It is generally appropriate to use about 3 meters. 2. Fixed rainproof film. On both sides of the shed film, a string of iron wire is used, and the upper end of the shed film is fixed under the shed film of the arch. The two ends of the wire are fixed, and the middle wire can be fixed tightly. The lower end can be fixed to the column under the tuyere, keeping the rainproof membrane at a 45-degree angle so that the rain can flow down into the canal after entering the shed. as the picture shows. Note: The rainproof membrane should be used on rainy days. In other fine weather, it is recommended to put down the lower end of the membrane and close it so as not to affect the ventilation of the greenhouse.
