Product Description
Vertex Agriculture specializes in the manufacture of modern greenhouse
- Plastic film greenhouse is a greenhouse covered with plastic film. It is mainly composed of a skeleton and plastic film. The skeleton is generally made of metal (such as hot-dip galvanized steel pipe) or bamboo and wood, which plays a supporting role and can withstand the weight of the film and the pressure exerted by the external environment (such as wind, snow, etc.). Its shape is common single-slope greenhouse, double-slope greenhouse and so on. The roof of the double-slope greenhouse has two sloping surfaces, similar to the chevron roof of a house, which facilitates drainage and lighting.
Product Description
Skeleton material:
Commonly used are hot-dip galvanized steel pipes, which have good strength and corrosion resistance. It can withstand the weight of the film and a certain amount of snow pressure. The specifications of the steel pipe vary according to the size and design requirements of the greenhouse, generally small greenhouses may use steel pipes with a diameter of 20-30 mm, and large greenhouses may use steel pipes with a larger diameter.
Plastic film:
In addition to the commonly used PE film and PO film, there are some functional films. For example, diffuse reflective film, which can make the sunlight more evenly distributed in the greenhouse, to avoid local light is too strong. There are also anti-fogging films, which prevent the formation of water droplets on the inner surface of the greenhouse, because the water droplets affect the light transmission and can drop on the plants, causing disease.
Ventilation system: including natural ventilation and forced ventilation. Natural ventilation is generally achieved by installing vents on both sides of the greenhouse, which can be opened manually or automatically through a film winder. When the temperature difference and pressure difference between the indoor and outdoor are generated, the air is exchanged through the vents to adjust the temperature and humidity in the room. Forced ventilation is the use of fans and other equipment to force the outside fresh air into the greenhouse to discharge the indoor dirty air, which has a significant effect on regulating the indoor environment in the case of high temperature in summer.
Shading system: In order to prevent summer glare from harming crops, thin-film greenhouses are usually equipped with shading systems. There are two kinds of sunshade system: inner sunshade and outer sunshade. The outer sunshade is to install a sunshade net on the outside of the top of the greenhouse, which reduces the solar radiation heat entering the greenhouse by blocking the sunlight. The sunshade net can be retracted according to the needs of the operation; Internal shading is the installation of shading facilities inside the greenhouse, which in addition to having a certain shading and cooling effect, can also play a certain role in insulation.
Insulation system: At night or in the cold season, the insulation system plays an important role. The common insulation measure is to set up a thermal insulation quilt or straw curtain inside the film greenhouse. The thermal insulation is generally made of multi-layer materials, such as needle felt, thermal insulation cotton, etc., which can be conveniently covered or put away by the roll and release mechanism to improve the thermal insulation performance of the greenhouse.
Product characteristics
Light transmittance
The light transmittance of the film is the key factor to ensure the photosynthesis of crops in the greenhouse. High-quality film in the clean state of light transmittance of up to 80%-90%, can make a lot of natural light into the greenhouse. However, with the extension of the use time, the surface of the film will absorb dust, water droplets, etc., and the light transmittance will gradually decrease. For example, after a period of use in a dusty environment, the light transmittance may be reduced to about 70%, which requires regular cleaning of the film to maintain good light transmittance. |
Insulation property
The thermal insulation performance of the film greenhouse is slightly worse than that of the glass greenhouse, but the growth needs of many crops can be met through reasonable thermal insulation measures. At night, the film can prevent the rapid loss of indoor heat, and the temperature difference between indoor and outdoor can generally be maintained at about 10-15 ° C. For example, in winter, when the outside temperature is -5 ° C, through the joint action of insulation and film, the temperature in the greenhouse can be maintained at about 5-10 ° C, providing suitable temperature conditions for the growth of some hardy vegetables such as spinach and leeks. |
economy
The construction cost of thin-film greenhouses is relatively low. Compared with the glass greenhouse, its material costs and construction costs are only about 1/3-1/2 of the glass greenhouse. This makes the film greenhouse widely used in agricultural production, especially suitable for small and medium-sized farmers. At the same time, the replacement cost of the film is also low, and when the film is damaged or the light transmission and insulation are seriously decreased, the operation of replacing the film is relatively simple and the cost is not high. |

Vegetable cultivation
The film greenhouse is suitable for growing a variety of vegetables, such as tomatoes, cucumbers, eggplants and other warm vegetables. In northern China, in spring, thin-film greenhouses can be used in advance for seedling cultivation and planting, so that the market time of vegetables is 1-2 months earlier than that of open field planting. In autumn, it can extend the growth cycle of vegetables and improve the yield and quality of vegetables. For example, cucumbers grown in thin film greenhouses, due to the relative stability of the environment in the greenhouse, grow faster, and the yield can be increased by about 30%-50% than that of open field planting. | floriculture
For flower growing, thin-film greenhouses can provide the right temperature, humidity and light conditions. Many ornamental flowers such as rose and carnations can be cultivated in thin film greenhouses. It can provide a thermal insulation environment for flowers in winter, prevent flowers from freezing damage, and adjust the environment through shading and ventilation system in summer to meet the needs of flower growth. Moreover, the film greenhouse can flexibly adjust the environmental parameters in the greenhouse according to the growth stage of flowers and different requirements for the environment. | Grow seedlings
Thin film greenhouse is an ideal place to grow seedlings. Its good light transmittance and relatively stable temperature environment are conducive to seed germination and seedling growth. Seedlings of vegetables, flowers, seedlings, etc., can be grown in bulk and then transplanted to open fields or other greenhouse environments for further growth. In the process of seedling cultivation, it is also possible to cultivate healthy seedlings by adjusting factors such as humidity and light intensity in the greenhouse. For example, when breeding pepper seedlings, the film greenhouse can control the temperature at 20-25 ° C and the humidity at about 60%-70%, providing good conditions for the germination of pepper seeds and the growth of seedlings. |
