Tropical Arches Agricultural Growing Poly Sheeting For Greenhouse
Tropical arches can effectively prevent the loss of heat and the flow of cold air and the loss of heat, which helps to reduce the temperature and dehumidify in summer; Ability to reduce condensation and drip, reducing the incidence of pathogens caused by excessive humidity; single-layer film greenhouse users can flexibly choose the number and height of the top and side roller blinds according to actual needs and weather conditions, thereby adjusting the inside of the greenhouse For the characteristics of increased rainfall in the south, single-layer membrane greenhouses use large-capacity gutters to ensure timely rainwater discharge. The cost of thin film greenhouse is low and it is suitable for large-scale promotion in my country.
The tropical arch dual-mode greenhouse refers to a greenhouse with a hot-dip galvanized steel frame and a film as a lighting material. The main structure of this type of greenhouse is simple and practical, and the cost is low. The top can be covered with double arch double film or single layer film, and the surrounding can be covered with double layer film, single layer film, pc board or glass, which can realize automatic control, optional supporting facilities, external sunshade system, internal sunshade system, fan water curtain Cooling system, top-window ventilation system, supplementary light system, seedbed nursery system, sprinkler system, computer control system, etc.
1 Compared with traditional greenhouses, greenhouses exist in multi-span forms. Compared with traditional greenhouses, greenhouses are a bright spot, and the utilization area is much larger than traditional greenhouses.
2. The management is more unified than traditional greenhouses, and the operation is more scientific, saving time and improving efficiency.
1 Ventilation and dehumidification. Ventilation is a good way to reduce humidity. Ventilation must be carried out at high temperatures, otherwise the indoor temperature of the multi-span greenhouse will drop. If the temperature drops too fast during the ventilation process, the vents should be closed in time to prevent the temperature from dropping suddenly and causing damage to the vegetables.
2 Cover with plastic film. Film mulching can reduce the evaporation of soil moisture and is an important measure to reduce indoor air humidity.
three. Heating and dehumidification. Using this method can not only meet the temperature requirements of vegetables, but also reduce the relative humidity of the air. When the plants have grown resistant, water them, heat them to about 30°C for 1 hour, and then ventilate them to remove moisture. After 3-4 hours, when the temperature in the shed is below 25°C, it can be repeated once.
4 Use insulation materials with good moisture absorption. Non-woven fabrics and other thermal insulation curtain materials with good moisture permeability and moisture absorption can prevent condensation on the inner surface of the shed and prevent dew from falling on the plants, thereby reducing the air humidity of the multi-span greenhouse.
5 Natural moisture absorption. Materials such as rice straw, wheat straw, quicklime, etc. can be used to lay the rows to absorb water vapor or mist to achieve the purpose of dehumidification.

How To Build A Greenhouse?
1. for your installation, we will provide you with one-on-one professional drawings.
2. We also offer engineers direct home-to-home instruction and installation services. All flight tickets, accommodation, meals and other costs of the engineers must be borne by you. The fee for the engineer is USD 100 / person / day.
1.Tunnel greenhouse logs are the lowest cost and the easiest to build. The frame is the first structure of the tunnel greenhouse. It is a treasure, a door, a fortune, an arch, an end column and so on. It is only between 6-12 m in level. This benefit is in the maximum use of space, simple structure, strong life and long life. After all, it is very convenient to complicate, build and repeat. This wealth is the lowest, but the most affordable.
2.The tunnel is one of the simplest structures of the greenhouse wind gun. The film is 100% PE new with UV dependence. It is strong, long-lasting, protects the temperature and protects water, organizes plant growth, protects fruits and plants.
3..This greenhouse is simply installed, is framed by galvanized tubes. There is no proper column in the greenhouse, so the mechanics can enhance, place and use the lighting effects of operations and good work.
