Crops<\/a> > Ornamentales<\/a> > Roses The use of Greenhouses in the cultivation of roses<\/strong> makes it possible to produce flowers at times and in places where it would otherwise not be possible.<\/p>\n<\/div><\/div><\/div> For this purpose, large greenhouses<\/strong> are required, their light transmission must be adequate, they must also be high and ventilation in the hot months must be good.<\/p>\n<\/div><\/div><\/div><\/div><\/div> It is recommended that heating<\/strong> be used during the winter, together with the installation of thermal blankets to conserve heat during the night.<\/p>\n<\/div> Temperature<\/strong> > above 20-24\u00baC.<\/p>\n<\/div><\/li> Relative humidity<\/strong> > around 98-100%.<\/p>\n<\/div><\/li><\/ul> Temperature<\/strong> > 17-25\u00baC.<\/p>\n<\/div><\/li> Minimum vegetative temperature<\/strong> > 15\u00baC, maximum 32\u00baC.<\/p>\n<\/div><\/li> Relative humidity<\/strong> > around 70-75%.<\/p>\n<\/div><\/li> It needs high light levels<\/strong> > the higher the light level the higher the production. In the summer months, when high light intensities and long day length prevail, flower production is higher than during the winter months. They are often irradiated for 16 h with artificial lighting in northern latitude countries to improve winter production in quality and quantity.<\/p>\n<\/div><\/li><\/ul><\/div><\/div> High RH<\/strong>: Fungi are favoured<\/p>\n<\/div><\/li> At low light levels:<\/strong> This leads to blind canes and fewer basal shoots, which results in less flower production. In addition, the flowers under these conditions are less brightly coloured and vegetation of the plant is difficult. It contributes to the development of fungi.<\/p>\n<\/div><\/li> High temperatures:<\/strong> temperatures above 40\u00b0C are lethal, above 30\u00b0C they produce small flowers with few petals and a pale colour.<\/p>\n<\/div><\/li> Low temperatures:<\/strong> they produce more petals, causing a physiopathology called bull’s head, which is a malformation of the flower. They produce more anthocyanin, i.e. a more reddish colour. Temperatures below -18\u00baC are lethal and vegetative arrest occurs at -1\u00baC. Flower buds are formed from 14\u00baC onwards.<\/p>\n<\/div><\/li><\/ul><\/div><\/div><\/div><\/div> Depending on the area, high-tech greenhouses are often used for rose cultivation.<\/p><\/div><\/div><\/a><\/span><\/div><\/div><\/div> Drip irrigation or hydroponics systems with recirculation systems are often installed to save water.<\/p><\/div><\/div><\/a><\/span><\/div><\/div><\/div> The greenhouses are equipped with climate control systems, heating systems, humidity and temperature control.<\/p><\/div><\/div><\/a><\/span><\/div><\/div><\/div> They are usually grown in inert substrates, usually in perlite, with hydroponic systems, and in northern European countries artificial lighting and carbon fertilisation are used for production.<\/p><\/div><\/div><\/a><\/span><\/div><\/div><\/div><\/div><\/div> Novagric implemented advanced greenhouses for the production and export of hydroponic hydrangeas in Chile, with climate control and fertigation.<\/p> Novagric created a centre of excellence in protected agriculture at a university in India, with advanced technology for growing vegetables, flowers and medicinal plants, adapted to local conditions and automatically controlled.<\/p> Novagric has carried out a project in Vietnam of Multi-span Gothic Greenhouses technologically equipped for Flower Crop such as Lilies.<\/p> Novagric designed, manufactured and built multi-span greenhouses in Puebla de V\u00edcar, Almer\u00eda, for Finca Viveros Las Fresas.<\/p> Novagric has carried out a project of Multi-span Chapel and Asymmetric Greenhouses to produce tropical ornamental plant.\n\n\n<\/p> Novagric implemented an irrigation and climate system for Vicaplant in La Mojonera, specialized in horticultural and ornamental plants.<\/p>
