In recent years, there has been a boom in greenhouses construction all over the country. Due to different technical conditions, there are inevitably more or less loopholes. Our company's experts have summarized the following points based on the technical experience of greenhouses construction in various places:
1. Too little space between the sheds.
Some farmers in order to save land, the distance between the two sheds is too narrow, some even only about 2 meters, leaving a hidden trouble for the greenhouses. First of all, the front of the winter greenhouse on the back of the shade is too large, so that the first half of the greenhouse vegetable growth is unfavorable. Secondly, it is harmful to drainage. There will be snow in winter, snow shed before the piling up of the situation.
Expert proposal: the correct distance of the open space between two sheds is advisable with 4, 5 meters, do not shade each other so, can prevent wind again.
2. The greenhouse lacks drainage system in rainy season.
Many farmers did not consider the problem of drainage of greenhouses when they built their tents, and there were no preventive measures. As a result, when it rained heavily in summer, the rainwater left on the shed surface collected in the "front" of the shed, and there was no place to flow. People could not get in for several days, and even the front of the greenhouses was washed away.
The expert suggests: correct method is, the face before shed is in dig a thing to go toward the same length drainage ditch with big shed, drainage ditch width is about half meter, the depth is about 30 centimeters left and right sides. So that the water left on the surface of the shed at any time, to prevent water into the shed.
3. The distance between the two rear columns in the greenhouse is too large.
Between the rear two columns in the greenhouse, the part of the ceiling of the shed is often the place where the rolled straw curtain and the drape machine are parked. This part can be said to be the place where the pressure is great, which often deforms the skeleton above.
Expert proposal: this two row stanchions interval is narrowed as far as possible, should be in 80 centimeters left and right sides, the cement ditch that builds an east and west to walk concurrently in the middle can.
4. The slope behind the earth wall of the greenhouse lacks protection measures.
Some huts do not cover this part of the back slope, so that the summer is often washed by rain, thus affecting the use of the years of the shed. Some of the shacks are covered with a plastic sheet on the back slope, but they are often exposed to the sun and the wind.
The expert suggests: a layer of plastic sheet is wrapped on the slope behind the greenhouse, and then a layer of non-woven cloth on the outside of the bread. Every 10 meters or so with a wire seal, so you can guarantee about five years, there is no problem
