Bamboo greenhouses, as an economical and practical agricultural facility, play an important role in agricultural production. It can not only regulate light, temperature and humidity to provide a suitable growing environment for crops, but also effectively resist natural disasters and improve the yield and quality of crops. Below, we will introduce the construction methods and steps of bamboo greenhouses in detail.
1. Preparation of materials
The main materials that need to be prepared to build a bamboo greenhouse include bamboo poles, iron wires, plastic films, ropes, etc. As the skeleton of the greenhouse, bamboo poles are required to have a moderate diameter, tough texture, and no pests and diseases. Iron wire is used to fix bamboo poles and plastic films, and products with corrosion resistance and high strength should be selected. Plastic film is the main material for covering greenhouses, which requires good light transmittance, aging resistance and stretch resistance. Ropes are used to secure the plastic film, ensuring that it fits snugly against the bamboo poles.
2. Site selection and planning
When choosing a site to build a bamboo greenhouse, it is necessary to fully consider factors such as light, water source, and soil. The site should be flat, well-drained, and easily accessible, while avoiding tuyeres and flood-prone areas. When planning the layout of the greenhouse, it is necessary to make a reasonable design according to the terrain, light and the growth needs of crops to ensure that the light in the greenhouse is uniform and the temperature is appropriate.
3. Construction steps
1.Determine the size and direction of the greenhouse: determine the length, width and height of the greenhouse according to the actual needs. Generally speaking, the length of the greenhouse can be determined according to the length of the plot and the ease of operation, the width is 6-12 meters, and the height is determined according to the growth needs of the crops and the local climatic conditions. At the same time, determine the direction of the greenhouse, generally in the north-south direction, in order to make full use of light energy.
2.Excavation foundation: Dig trenches with a depth of about 30 cm and a width equal to the width of the greenhouse at both ends of the greenhouse for fixing bamboo poles. The trench should be smooth and solid to ensure the stability of the greenhouse.
3.Build the skeleton of the bamboo pole: according to the planned size, insert the bamboo pole into the groove and fix it with wire or rope. The spacing of the bamboo poles should be even, generally 1-15 meters. The top of the bamboo pole should be connected with wire or rope to form a stable arch structure.
4.Cover the plastic film: Unfold the plastic film and cover it on the skeleton of the greenhouse. The film should be tightened and flattened, leaving no wrinkles and voids. Wire or rope is attached to the bamboo pole around the film to ensure that the film is stable and not blown by the wind.
5.Set up vents and doorways: Set up vents at both ends of the greenhouse to adjust the temperature and humidity in the shed. The size of the vent should be determined according to the actual needs, generally about 1 3 of the width of the greenhouse. At the same time, a doorway is set at one end of the greenhouse to facilitate access and management.
6.Fix ropes and wires: Use ropes and wires to fix plastic films and bamboo poles firmly to ensure that the greenhouse will not collapse or deform in the wind and rain. When fixing, it is necessary to pay attention to the tightness of the rope and wire, not only to ensure the fixing effect, but also to avoid damage to the film or bamboo pole caused by too tightness.
4. Precautions
1.Choose the right bamboo pole and plastic film: the diameter, length and quality of the bamboo pole should meet the requirements, and the light transmittance, aging resistance and stretch resistance of the plastic film should be good. The selection of these materials will directly affect the use effect and life of the greenhouse.
2.Pay attention to safety during construction: In the process of digging trenches, carrying bamboo poles and covering films, it is necessary to pay attention to safety and avoid accidents. At the same time, it is necessary to take personal protective measures, such as wearing gloves and work shoes.
3.Ensure the stability of the greenhouse: During the construction process, it is necessary to ensure the stability of the greenhouse. The fixation of bamboo poles and plastic film should be firm and reliable to prevent the greenhouse from collapsing or deforming due to wind and rain and other reasons.
4.Reasonable setting of vents and doors: The setting of vents and doorways should be reasonable, not only to ensure the ventilation effect, but also to avoid excessive heat loss. At the same time, the location of the doorway should be easy to enter and manage.
5. Post-maintenance and management
The built bamboo greenhouse needs to be regularly maintained and managed to ensure its normal use and prolong its service life. Specific measures include: regularly checking the integrity of bamboo poles and plastic films, and replacing damaged parts in a timely manner; Regularly clean up the debris and stagnant water in the greenhouse to keep the internal environment clean and tidy; Adjust the size and number of vents according to crop growth needs and climatic conditions, etc.
In short, building a bamboo greenhouse requires the preparation of sufficient materials, the selection of a suitable site, the construction in accordance with the standardized steps, and regular maintenance and management during use. Only in this way can we give full play to the role of bamboo greenhouses in agricultural production and improve the yield and quality of crops.
