| Abstract:
Ventilation in greenhouses is a very important problem for the mediterranean areas : at the beginning of April the temperature rises at such a problem that it is impossible to obtain a crop without a good ventilation system. Generally the grower has to stop any work in greenhouses with bad effects on the economy. The mediterranean growers do not have as sophisticated greenhouses as northern growers have and they must look for very simple systems. New plastic greenhouses are tight. This has an influence on the CO2 concentration and humidity level. For all these reasons we have to imagine new systems for static ventilation in greenhouses. This paper sums up 2 years of experiments on 3 static ventilation systems in a plastic tunnel. | |
