“Why is there a lot of film on the lower part of your shelter that is facing the bottom of the air outlet. What is it used for?†The reporter asked Master Liu when interviewing Mr. Liu, the vegetable farmer of Zaohu Village, Dongxia Town, Qingzhou City.
“This is used to prevent rain. The shed film on my shed is seriously damaged, especially the shed film at the bleed outlet. Because it needs to be ventilated and often switched, the shed film is seriously worn and the holes are more. Once it rains, it will It will cause a lot of rainwater to flow into the shed from the hole at the outlet, causing the ridge to be damaged. So I laid a film under the bleeder so that when the rain shed, it would not wash the ridge. And can directly flow to the cultivation line." Master Liu said.
Actually, Master Liu’s approach is tantamount to a headache and a foot massage. It has little effect on the rain protection of the shed, and it also affects the growth of vegetables in the shed. It is better to keep the rain out of the shed. it is good. So how can a vegetable farmer prevent rainwater from flowing into the shed?
First, a vegetable farmer can take a piece of film with a width of about 50 cm and a length equal to the length of the greenhouse, and then fix it on the upper side of the air outlet in the shed. When it rains, put down the added film and put it under the air outlet. The upper part of the side membrane, so that rain can flow down the upper part of the membrane to prevent rain from flowing into the greenhouse.
Secondly, the vegetable farmer can also wipe the shed film at the outlet opening with holes, then apply special glue around the holes in the film, and then use a clean film to stick to the hole, so that it will only rain when it rains. When the air outlet is closed tightly, the rainwater can be prevented from flowing into the greenhouse from the broken hole of the air outlet.
Once again, vegetable farmers can use special tape for the film to bind the holes at the outlet of the shed film to prevent rainwater from flowing into the greenhouse during rain.
