Greenhouse production is the practice of growing plants, vegetables, flowers and herbs within an enclosed space under controlled environmental conditions. The structure usually made from glass or plastic protects the crop from the cold, heat, wind, rain, and pests, while allowing optimum growing conditions to maximise yields.  3, fiche 1, Anglais, - greenhouse%20production

Types of Plastic Coverings... Polyvinyl chloride film has very high emissivity for long-wave radiation, which creates slightly higher air temperatures in the greenhouse at night. UV inhibitors can increase the life of the film. It is more expensive than polyethylene film and tends to accumulate dirt, which must be washed off in winter for better light transmission.  3, fiche 2, Anglais, - polyvinyl%20chloride%20film

La lutte contre le gel est un mode de protection largement utilisé en arboriculture. Les filets antigrêle constituent certainement la technique la plus efficace pour protéger des cultures fragiles contre la grêle. Dans certaines régions très ensoleillées on protège par des ombrages les jeunes semis de certaines plantes sensibles à ce stade à un excès de lumière solaire; ces ombrages peuvent être naturels ou artificiels. Les serres et autres abris permettent d'assurer une protection encore plus efficace : on a alors affaire à des cultures sous abri.  2, fiche 3, Français, - culture%20prot%C3%A9g%C3%A9e

A new development in mulch technology is the wavelength-selective film. It provides much of the weed control benefit of black plastic mulch, but warms the soil more than does black mulch. Thermic films, such as the IR-303 Thermofilm, were originally developed as greenhouse covers. They are reputed to reduce maximum and increase minimum temperatures slightly more than standard polyethylene films. These thermic films may have a role as hoop-supported row covers(tunnels). In a preliminary trial in 1990, the combination of black mulch and tunnels of either Lutrasil or IR-303 Thermofilm produced greater early yield than either black film or wavelength-selective mulch films alone.  2, fiche 4, Anglais, - wavelength%20selective%20mulch

Weed control from herbicides applied before the mulch may break down in advance of crop maturity. An alternative to the clear mulch/herbicide system is the IRT or wavelength selective mulch system.

High tunnels are not conventional greenhouses. But like plastic-covered greenhouses, they are generally quonset-shaped, constructed of metal bows that are attached to metal posts which have been driven into the ground about two feet deep. They are covered with one layer of 6-mil greenhouse-grade polyethylene, and are ventilated by manually rolling up the sides each morning and rolling them down in early evening. There is no permanent heating system although it is advisable to have a standby portable propane unit to protect against unexpected below-freezing temperatures. There are no electrical connections. The only external connection is a water supply for trickle irrigation. The ends of the tunnels are framed in, and may be made portable(removable) to facilitate easy access into the tunnel with a small tractor and tiller.  5, fiche 7, Anglais, - high%20tunnel

Greenhouse effect(...) The transparent glass or plastic walls and roof of the greenhouse transmit the shorter wavelength, visible light and infrared radiation from the sun but not the longer wavelengths. Thus, during the hours of daylight infrared radiation passes into the greenhouse and warms its atmosphere and the ground on which the house stands. The transparent walls and roof of the greenhouse partly reflect and partly absorb the longer wavelength radiation. Subsequently the walls and roofs re-emit the absorbed radiation into the house. Coating the glass with a non-heat-radiating film, which is transparent to sunlight, further maximizes the heating effect of radiation received.  2, fiche 10, Anglais, - reinforced%20greenhouse%20effect
