Vegetable greenhouse construction is prone to problems
Our company applies the best results in the life sciences to fight against disease, and benefits more people who need help and are willing to work with us to create a miracle of life. The following is a description of the problems that are likely to occur in the construction of vegetable greenhouses.
1. There are too few open spaces between the two sheds. In order to save land, some farmers have too narrow a distance between the two sheds, and some even have about 2 meters, leaving hidden dangers to the greenhouse. First of all, the greenhouse in front of the winter is too dark for the back, which makes the growth of the first half of the greenhouse unfavorable. Secondly, it is extremely harmful to the drainage. There will be cases where the snow canopy can not be piled up in winter when it snows.
Experts suggest that the correct distance between the two sheds is 4-5 meters, so that they are neither shaded nor windproof.
2. The greenhouse lacks the rainy season drainage system. Many farmers did not consider the problem of greenhouse drainage when they built the shed. There was no precautionary measure, so that when the rain was heavy in summer, the rainwater left on the shed was collected in the front face of the shed, and there was no local flow. Not going to people, even the phenomenon that the front of the greenhouse was washed away.
Expert suggestion: The correct way is to dig a thing at the front of the shed and go to the drainage ditch with the same length as the greenhouse. The drainage ditch is about half a meter wide and about 30 cm deep. So that the water left on the shed will flow away at any time to prevent water from flowing into the shed.
3. There is no protection measures for the back slope of the greenhouse wall. Some large sheds do not have covering facilities on the back slope, so that they are often washed away by rain in summer, thus affecting the service life of the greenhouse. Although some shacks are covered with a layer of plastic cloth on the back slope, they are often exposed to the wind and the sun. After less than a year, the back slope is exposed again.
Experts suggest: a layer of plastic cloth on the back slope of the greenhouse, and a layer of non-woven fabric on the outer bread. Seal it with a wire every 10 meters or so, so that it can be guaranteed for five years or so. There is not much problem.
4. The distance between the last two rows of columns in the greenhouse is too large. Between the two rows of columns in the shed, the shed surface on the top is often the part of the rolled straw curtain and the roller blind machine. This part can be said to be the place with the most pressure, which often deforms the upper skeleton. .
The above is the problem that is easy to appear in the construction of vegetable greenhouses. I hope to help you.
