Mediterranean countries offer very favorable climatic conditions for growing plants in a protected environment: as matter of fact, the high solar radiation allows use greenhouses with simple structures, covered plastic film and without fixed installations winter heating. They are called “Mediterranean greenhouses” totally different from those Central Northern Europe. In photovoltaic greenhouses, cover on pitch facing south is usually replaced by opaque panels. However, this solution...

Forest biodiversity conservation is one of the most interesting and crucial problems in forestry world. Currently, methods are based on two phases: seeds at low temperatures multiplication vegetable material. This latter operation can be successfully developed properly designed greenhouses. The aim this paper to define a type greenhouse which particularly suitable for plant material propagation order preserve forest area Central Italy. Some general parameters were first defined correct...

In recent years the use of photovoltaic panels as cover materials for greenhouses developed a great interest due to state’s incentives obtainable by such applications. Shading caused these elements inside structure appears be often too much normal development agricultural activity. this study it was analyzed behaviour shading prototype dynamic greenhouse whose particularity lies in possibility rotation along longitudinal axis. The panels’ allows varying degree function some parameters...

In recent years, the increasing interest in energy production from renewable sources has led to photovoltaic elements being placed on greenhouse coverings. The shading of crops by these can, however, cause problems regarding normal course agricultural activity. All studies thus far application (PV) panels as a covering material have focused flat roof structures. Tunnel greenhouses, due their curved shape, do not lend themselves easily accommodating PV even part cover. this study, we analysed...

The Italian dairy production is characterized by high heterogeneity. typology quantitatively more important (80% of national production) represented cow’s milk cheeses (<em>Grana Padano</em> cheese, string Parmesan etc.), while the cheese from buffalo’s (especially such as <em>mozzarella</em>) and sheep goats represents respectively 4% 8% production, are linked to specific regional contexts. Some phases cycle processing occur at certain temperatures that not...

The use of plastic film coverings has made a significant contribution to the development greenhouses in Italy and new generation that differ from those Central Northern Europe: so called <em>Mediterranean Greenhouse</em>. This is simple structure with cheap emergency artificial heating systems. During winter season, available solar energy more than sufficient meet requirements. hot however, intense radiation high air temperatures are problematic. Different active passive...

This is simple structure with cheap emergency artificial heating systems. During winter season, available solar energy more than sufficient meet requirements. hot however, intense radiation high air temperatures are problematic. Different active passive strategies are, therefore,...

The southern Italian regions are characterized by climatic conditions with high values of solar radiation and air temperature. This has allowed the spread protected structures both as a defense against critical winter for growing off-season. major energy source these greenhouses is given artificial used rarely. So problem in use areas, if anything, opposite to that northern areas. In places you must try mitigate often inside suitable measures or abandon few months cultivation structures....

The analysis of the energy requirements carried out using simple algorithms and historical air temperature series allows to obtain a classification territory, identifying those areas where demand for artificial heating greenhouses is limited, resulting in reduced costs management greenhouse gas emissions. In this work were determined annual heat (MJ m -2 year -1 ) covered with polyethylene film whole Italian territory at predetermined internal thermal threshold. results show that through has...

The use of chemicals has raised more than a doubt in the public interest on actual capacity active principles to enter food chain. No less important is discourse concerning safety workers that, using industrial formulated fight adversities grapevine, appear be directly exposed products which, by typology and dangerousness, could determine professional diseases. 1194 Filippo Cossio et al. research was carried out seven wine farms (4 organic 3 conventional). Aim assess whether work performed...
