El concepto de invernadero también apareció en los Países Bajos y luego en Inglaterra en el siglo , junto con las plantas. Algunos de estos primeros intentos requirieron enormes cantidades de trabajo para cerrar por la noche o prepararlos para el invierno. Hubo serios problemas para proporcionar calor adecuado y equilibrado en esos primeros invernaderos. El primer invernadero de 'estufa' (calentado) en el Reino Unido se completó en Chelsea Physic Garden en 1681.[22] Aún hoy en día, los Países Bajos tienen muchos de los invernaderos más grandes del mundo, algunos de ellos tan grandes que pueden producir millones. de verduras cada año.
La experimentación con el diseño de invernaderos continuó durante el siglo en Europa, a medida que la tecnología producía mejores vidrios y mejoraban las técnicas de construcción. El invernadero del Palacio de Versalles fue un ejemplo de su tamaño y elaboración; tenía más de de largo, de ancho y de alto.
Al botánico francés Charles Lucien Bonaparte se le atribuye a menudo la construcción del primer invernadero práctico y moderno en Leiden, Holanda, durante los años 1800 para cultivar plantas tropicales medicinales.[23] Los invernaderos, originalmente solo en las propiedades de los ricos, con el crecimiento de la ciencia de la botánica se dispusieron en las grandes universidades. Los franceses llamaron a sus primeros invernaderos orangeries"), ya que servían para proteger los naranjos de las heladas. A medida que las piñas se hicieron populares, se construyeron pineries, o pozos de piña.
19th century
Industrialization opened new possibilities for the use of iron and glass as construction materials. At the beginning of the century in England, George Steward Mackenzie and John Loudon experimented with curvilinear houses, which were greenhouses with semicircular iron and glass roofs to take advantage of as much sunlight as possible evenly. In 1812, Mackenzie designed a quarter-sphere-hothouse for growing peaches and grapes, which consisted of a glass quarter-sphere in front of a brick wall. In 1818, Louden set up several test greenhouses at Bayswather, near London, to find the most favorable form of construction for optimal solar radiation. In 1817 he published Remarks on the Construction of Hothouses and in 1818 Sketches Of Curvilinear Houses, which were received throughout Europe and significantly influenced the later development of glass house construction.[24]
The golden age of greenhouses Victorian England, when the largest greenhouses ever conceived were built; Those tall enough for large trees were often called palm houses. They were usually in public gardens and parks. They were a stage in the century's development of glass and iron architecture, which was also widely used in railway stations, markets, exhibition halls and other large buildings that needed a large, open-plan internal area. One of the earliest examples of a palm house is in Belfast Botanic Gardens. Designed by Charles Lanyon"), designed in 1839 and completed in 1840, it is one of the world's earliest examples of a curvilinear greenhouse. It consists of two wings, the cool wing and the tropical wing containing the vault. Lanyon altered his original plans to increase the height of the vault, thus allowing for much taller floors. It was built by the iron manufacturer Richard Turner. Joseph Paxton also relied on Turner for the construction of The Great Conservatory in the park of Chatsworth House (1837-1840), which was a model for another of his works, the Palm House in the Royal Botanic Gardens, Kew, London. In 1850, Paxton built a house for tropical water lilies with a heated swimming pool, the Victoria Regia conservatory, also in Chatsworth. also built in 1851 by Paxton. Both Paxton buildings have disappeared.[25].
An early example of an iron and glass greenhouse outside Britain is the Serre des cactées in the Jardin des Plantes in Paris, built by Charles Rohault de Fleury") in 1834-1836.
The oldest known hot water central heating system was built by Marten Trifvald in 1716 for a Newcastle greenhouse. However, it was not until the 1830s that steam heating became widespread in greenhouses and replaced the old individual ovens.
These greenhouses, also called "plant museums," which staged exhibits brought together in a spirit of mastery of nature and exoticism, spread as commercial entertainment venues in the second half of the century in the metropolises of Europe and North America, especially in botanical gardens and in urban parks. For example, the Schönbrunner Palmenhaus "Palmenhaus (Schönbrunn)") ('Schönbrunn Palm House'), 111 m long, 29 m wide and 25 m covered with 45,000 glass panels, opened in Vienna in 1882 and was one of the three largest of its time in the world (with the Knew Garden and the Palm Garden of Frankfurt am Main (1868-1870). In Berlin, from 1905 to 1907, the Große Tropenhaus ('great tropical house') was built in the botanical garden. Notable examples of the greenhouse architecture of the century are the Serre du Congo in the Jardin des Plantes in Paris and the Grote Wintertuin in the castle park Laken) in the north of Brussels.
The construction, heating and maintenance of large tropical houses constantly required enormous costs. Only when wealthy manufacturers and merchants were able to emulate the lavish lifestyle of the nobility did glass houses also emerge as places of private bourgeois performance, where festivals were held and tropical flora was the subject of high-level conversation. Since the use of refrigeration technology and the acceleration of overseas logistics, tropical fruits have increasingly reached Europe and taken away the exotic appeal of greenhouses. Although public palm houses were still maintained and recently built in botanical gardens, they have hardly been built as private representative buildings since the end of the century. Historic glass houses as part of village architecture rarely survived changes in ownership, corrosion damage, storms, and vacancies.[26].
Other large greenhouses built in the century were the Crystal Palace (New York), built for the New York World's Fair in 1853 and burned down in 1856; the Glaspalast (Munich) in Munich, built to house the First German General Industrial Exhibition, held in 1854 and which was also destroyed by fire in 1931; and the Royal Greenhouses of Laeken (1874-1895) for King Leopold II of Belgium. In Japan, the first greenhouse was built in 1880 in the Enoshima Tropical Plant Garden by Samuel Cocking"), a British merchant who exported herbs. It was destroyed by the Great Kantō earthquake of 1923.
20th century
In the 19th century, the geodesic dome was added to the many types of greenhouses. Notable examples are the Rodale Institute")[27] in Pennsylvania, the Climatron") at the Missouri Botanical Gardens in St. Louis, designed by T. C. Howard and completed in 1960, the world's first air-conditioned greenhouse and the first geodesic dome enclosed in rigid plexiglass (Perspex) panels; and Toyota Motor Manufacturing Kentucky").[28] The pyramid is another popular shape for large, tall greenhouses; there are several pyramidal greenhouses at the Muttart Conservatory") in Alberta (c. 1976). A well-known example of this form of construction is the Eden Project greenhouses in Cornwall, which opened in 2001 and are currently the largest greenhouses in the world. In the late 1980s, attempts were made to create a self-sufficient ecosystem in the greenhouse of the Biosphere 2 project.
Greenhouse structures were adapted in the 1960s when wider sheets of polyethylene (polyethylene) film became widely available. Arch houses were manufactured by various companies and were often also made by the growers themselves. Built with aluminum extrusions, special galvanized steel tubing, or even just lengths of steel or PVC water pipe, construction costs were greatly reduced leading to the construction of many more greenhouses on smaller farms and garden centers. The durability of polyethylene film increased considerably when more effective UV inhibitors were developed and added in the 1970s; these extended the life of the film from one or two years to three and finally four or more years.
Gutter-connected greenhouses became more common in the 1980s and 1990s. These greenhouses have two or more bays connected by a common wall or row of support posts. Heating inputs were reduced as the ratio of floor area to exterior wall area increased substantially. Gutter-connected greenhouses are now commonly used both in production and in situations where plants are also grown and sold to the public. Gutter-connected greenhouses are typically covered with structured polycarbonate materials or a double layer of polyethylene film with air blown between them to provide greater heating efficiency.
