Crops<\/a> > Vegetables<\/a> > Tomato<\/strong><\/p>\n<\/div> Tomato cultivation<\/strong> has demanding climatic requirements<\/strong>, so the use of greenhouses in tomato production is of vital importance (especially in temperate or cold climates).<\/p>\n<\/div><\/div><\/div> In the past, vine or scrape and grass<\/strong><\/a> greenhouses were used, but new cultivation techniques (trellising at high altitudes and hydroponic systems) require the construction of multi-tunnel<\/strong><\/a> greenhouses for their production.<\/p>\n<\/div><\/div><\/div><\/div><\/div> The necessary conditions<\/strong> for tomato cultivation<\/strong> are:<\/p>\n<\/div> Daytime temperature<\/strong> > 20-30\u00baC<\/p>\n<\/div><\/li> Night temperature<\/strong>\u00a0> 15-17\u00baC.<\/p>\n<\/div><\/li> Vegetative temperature<\/strong> > 12\u00baC-35\u00baC.<\/p>\n<\/div><\/li> Optimum temperature for fertilisation<\/strong> >between 12\u00baC y 25\u00baC, from these values is defective or zero.<\/p>\n<\/div><\/li> Relative humidity<\/strong> > Around the 60-80%.<\/p>\n<\/div><\/li><\/ul><\/div><\/div> High relative humidity:<\/strong> Favours the development of aerial diseases, cracking of the fruit and hinders fertilisation, due to the fact that the pollen is compacted, aborting part of the flowers.<\/p>\n<\/div><\/li> Low level of light:<\/strong> It has a negative effect on the processes of flowering, fertilisation and vegetative development of the plant. Contributes to the development of fungi.<\/p>\n<\/div><\/li> High temperatures:<\/strong> Temperatures above 45\u00b0C are lethal, above 35\u00b0C they affect fruiting, due to poor ovule development and the development of the plant in general and the root system in particular.<\/p>\n<\/div><\/li> Low temperatures:<\/strong> They produce a “Catface” physiopathy or pistillate woody scar. Tomatoes show large scars and holes in the pistillate end of the fruit, as well as lack of shape. Sometimes, the fruit is kidney-shaped with long scars.<\/p>\n<\/div><\/li><\/ul><\/div><\/div><\/div><\/div> High-tech greenhouses with hydroponic irrigation systems are (increasingly) used for tomato cultivation, usually on bags of substrate (rockwool, coconut fibre or perlite).<\/p><\/div><\/div><\/a><\/span><\/div><\/div><\/div> Localised irrigation systems are often used, depending on the production system. <\/p><\/div><\/div><\/a><\/span><\/div><\/div><\/div> Thermal and shading screens, forced ventilation, cooling systems or fog systems are used.<\/p><\/div><\/div><\/a><\/span><\/div><\/div><\/div> Typical in northern European countries and increasingly used in southern countries to increase agricultural production.
