When building a greenhouse, you should first prepare the tools you need, including construction lines, punching machines, gypsum, etc. According to the site, determine four angles, specific directions and specifications. It is suggested that the length from north to south is less than 80 meters and the width from east to west is 8 meters. After confirmation, defend the line as soon as possible, determine the position of the arch pipe every one meter, and then punch holes. Install the arch pipe, pull it horizontally, clamp the spring and groove, insect net and film, and finally install the door.

Columns can be made of logs or reinforced concrete columns, and the buried depth is 50-60 cm. The middle two rows should be higher than the ground, and the side two rows should be higher than the ground 1 m. The top of the column gradually decreases from the middle two rows to the east and west sides, and six rows are buried. Column spacing is not more than 2m, and vertical. Then use 12- 16 mm diameter steel bar to bend into arch reinforcement, and tie it to the top of the east and west columns as the skeleton.

Extended data:

Try to avoid the mechanical damage of the shed membrane, especially the bamboo shed. Before the film is buckled, the protruding part of the frame surface should be flattened or wrapped with old cloth. When fixed with a spring, the card slot should be padded with an old newspaper. In addition, attention should be paid to avoid long-term contact between old and new films, so as not to accelerate the aging of new films. Be careful when ventilating. Freezing or exposing the film to the sun will accelerate the aging.

When the steel pipe is exposed to the sun in summer, the temperature can rise to 60-70℃, thus accelerating the aging and rupture of the film. In the process of using the film, it is inevitable that there will be holes, so it should be repaired with glue or tape in time. Environmental characteristics and control Greenhouse is covered with plastic film, forming a relatively closed and open special microclimate. To cultivate vegetables in greenhouse, we must master the characteristics of greenhouse environment and take control measures.
