Greenhouse
A greenhouse (also called a glasshouse, or, if with sufficient heating, a hothouse) is a structure with walls and roof made chiefly of Transparent ceramics, transparent material, such as glass, in which plants requiring regulated climatic conditions are grown.These structures range in size from small sheds to industrial-sized buildings. A miniature greenhouse is known as a cold frame. The interior of a greenhouse exposed to sunlight becomes significantly warmer than the external temperature, protecting its contents in cold weather. Many commercial glass greenhouses or hothouses are high tech production facilities for vegetables, flowers or fruits. The glass greenhouses are filled with equipment including screening installations, heating, cooling, and lighting, and may be controlled by a computer to optimize conditions for plant growth. Different techniques are then used to manage growing conditions, including air temperature, relative humidity and vapour-pressure deficit, in ord ...

Orangerie Du Château De Versailles Le 11 Septembre 2015 - 90
An orangery or orangerie was a room or a dedicated building on the grounds of fashionable residences of Northern Europe from the 17th to the 19th centuries where orange and other fruit trees were protected during the winter, as a very large form of greenhouse or conservatory. The orangery provided a luxurious extension of the normal range and season of woody plants, extending the protection which had long been afforded by the warmth offered from a masonry fruit wall. During the 17th century, fruits like orange, pomegranate, and bananas arrived in huge quantities to European ports. Since these plants were not adapted to the harsh European winters, orangeries were invented to protect and sustain them. The high cost of glass made orangeries a status symbol showing wealth and luxury. Gradually, due to technological advancements, orangeries became more of a classic architectural structure that enhanced the beauty of an estate garden, rather than a room used for wintering pla ...

Relative Humidity
Humidity is the concentration of water vapor present in the air. Water vapor, the gaseous state of water, is generally invisible to the human eye. Humidity indicates the likelihood for precipitation, dew, or fog to be present. Humidity depends on the temperature and pressure of the system of interest. The same amount of water vapor results in higher relative humidity in cool air than warm air. A related parameter is the dew point. The amount of water vapor needed to achieve saturation increases as the temperature increases. As the temperature of a parcel of air decreases it will eventually reach the saturation point without adding or losing water mass. The amount of water vapor contained within a parcel of air can vary significantly. For example, a parcel of air near saturation may contain 28 g of water per cubic metre of air at , but only 8 g of water per cubic metre of air at . Three primary measurements of humidity are widely employed: absolute, relative, and specific. Ab ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cold Frame
In agriculture and gardening, a cold frame is a transparent-roofed enclosure, built low to the ground, used to protect plants from adverse weather, primarily excessive cold or wet. The transparent top admits sunlight and prevents heat escape via convection that would otherwise occur, particularly at night. Essentially, a cold frame functions as a miniature greenhouse to extend the growing season. Historically, cold frames were built to be used in addition to a heated greenhouse. The name itself exemplifies the distinction between the warm greenhouse and the unheated cold frame. They were frequently built as part of the greenhouse's foundation brickwork along the southern wall (in northern latitudes). This allowed seeds to be germinated in the greenhouse and then easily moved to the attached cold frame to be "hardened-off" before final planting outside. Cold frames are similar to some enclosed hotbeds, also called hotboxes. The difference is in the amount of heat generated inside. ...

Vapour-pressure Deficit
Vapour-pressure deficit, or VPD, is the difference (deficit) between the amount of moisture in the air and how much moisture the air can hold when it is saturated. Once air becomes saturated, water will condense out to form clouds, dew or films of water over leaves. It is this last instance that makes VPD important for greenhouse regulation. If a film of water forms on a plant leaf, it becomes far more susceptible to rot. On the other hand, as the VPD increases, the plant needs to draw more water from its roots. In the case of cuttings, the plant may dry out and die. For this reason the ideal range for VPD in a greenhouse is from 0.45 kPa to 1.25 kPa, ideally sitting at around 0.85 kPa. As a general rule, most plants grow well at VPDs of between 0.8 and 0.95 kPa. In ecology, it is the difference between the actual water vapour pressure and the saturation water vapour pressure at a particular temperature. Unlike relative humidity, vapour-pressure defici ...

Cucumber
Cucumber (''Cucumis sativus'') is a widely-cultivated Vine#Horticultural climbing plants, creeping vine plant in the Cucurbitaceae family that bears usually cylindrical Fruit, fruits, which are used as culinary vegetables.Cucumber " ''Encyclopædia Britannica''. [1998] 2019. Considered an annual plant, there are three main varieties of cucumber—slicing, Pickled cucumber, pickling, and Seedless fruit, seedless—within which several cultivars have been created. The cucumber originates from South Asia, but now grows on most continents, as many different types of cucumber are traded on the global market. In North America, the term ''wild cucumber'' refers to plants in the Genus, genera ''Echinocystis'' and ''Marah (plant), Marah'', though the two are not closely related.

England
England is a country that is part of the United Kingdom. It shares land borders with Wales to its west and Scotland to its north. The Irish Sea lies northwest and the Celtic Sea to the southwest. It is separated from continental Europe by the North Sea to the east and the English Channel to the south. The country covers five-eighths of the island of Great Britain, which lies in the North Atlantic, and includes over 100 smaller islands, such as the Isles of Scilly and the Isle of Wight. The area now called England was first inhabited by modern humans during the Upper Paleolithic period, but takes its name from the Angles, a Germanic tribe deriving its name from the Anglia peninsula, who settled during the 5th and 6th centuries. England became a unified state in the 10th century and has had a significant cultural and legal impact on the wider world since the Age of Discovery, which began during the 15th century. The English language, the Anglican Church, and Engli ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Chelsea Physic Garden
The Chelsea Physic Garden was established as the Apothecaries' Garden in London, England, in 1673 by the Worshipful Society of Apothecaries to grow plants to be used as medicines. This four acre physic garden, the term here referring to the science of healing, is among the oldest botanical gardens in Britain, after the University of Oxford Botanic Garden. Its rock garden is the oldest in Europe devoted to alpine plants and Mediterranean plants. The largest fruiting olive tree in Britain is there, protected by the garden's heat-trapping high brick walls, along with what is doubtless the world's northernmost grapefruit growing outdoors. Jealously guarded during the tenure of the Worshipful Society of Apothecaries, the garden became a registered charity in 1983 and was opened to the general public for the first time. The garden is a member of the London Museums of Health & Medicine. It is also Grade I listed in the Register of Historic Parks and Gardens of Special Historic Intere ...

Martial
Marcus Valerius Martialis (known in English as Martial ; March, between 38 and 41 AD – between 102 and 104 AD) was a Roman poet from Hispania (modern Spain) best known for his twelve books of ''Epigrams'', published in Rome between AD 86 and 103, during the reigns of the emperors Domitian, Nerva and Trajan. In these short, witty poems he cheerfully satirises city life and the scandalous activities of his acquaintances, and romanticises his provincial upbringing. He wrote a total of 1,561 epigrams, of which 1,235 are in elegiac couplets. Martial has been called the greatest Latin epigrammatist, and is considered the creator of the modern epigram. Early life Knowledge of his origins and early life are derived almost entirely from his works, which can be more or less dated according to the well-known events to which they refer. In Book X of his ''Epigrams'', composed between 95 and 98, he mentions celebrating his fifty-seventh birthday; hence he was born during March 38, 39, ...

Palace Of Versailles
The Palace of Versailles ( ; french: Château de Versailles ) is a former royal residence built by King Louis XIV located in Versailles, Yvelines, Versailles, about west of Paris, France. The palace is owned by the French Republic and since 1995 has been managed, under the direction of the Ministry of Culture (France), French Ministry of Culture, by the Public Establishment of the Palace, Museum and National Estate of Versailles. Some 15,000,000 people visit the palace, park, or gardens of Versailles every year, making it one of the most popular tourist attractions in the world. Louis XIII built a simple hunting lodge on the site of the Palace of Versailles in 1623 and replaced it with a small château in 1631–34. Louis XIV expanded the château into a palace in several phases from 1661 to 1715. It was a favorite residence for both kings, and in 1682, Louis XIV moved the seat of his court and government to Versailles, making the palace the ''de facto'' capital of France. This ...

Mandarin Orange
The mandarin orange (''Citrus reticulata''), also known as the mandarin or mandarine, is a small citrus tree fruit. Treated as a distinct species of orange, it is usually eaten plain or in fruit salads. Tangerines are a group of orange-coloured citrus fruit consisting of hybrids of mandarin orange with some pomelo contribution. Mandarins are smaller and oblate, unlike the spherical common oranges (which are a mandarin–pomelo hybrid). The taste is considered sweeter and stronger than the common orange. A ripe mandarin is firm to slightly soft, heavy for its size, and pebbly-skinned. The peel is thin, loose, with little white mesocarp, so they are usually easier to peel and to split into segments. Hybrids usually have these traits to a lesser degree. The mandarin is tender and is damaged easily by cold. It can be grown in tropical and subtropical areas. According to genetic studies, the mandarin was one of the original citrus species; through breeding or natural hybridization ...
