Agriculture And Aquaculture In Hong Kong
Agriculture and aquaculture in Hong Kong are considered sunset industries. Most agricultural produce is directly imported from the neighbouring mainland China. In 2006 the industry accounts for less than 0.3% of the labour sector. Geographically Hong Kong consists largely of steep, unproductive hillside. The local aquaculture industry is also facing challenges from competition with imported aquatic food products and concern of fish and seafood safety.Hong Kong Agriculture, Fisheries and Conservation Department. Fish Aqu." ''Fishing Aquaculture.'' Retrieved on 3 April 2007. History In the colonial Hong Kong era around the 1850s, agriculture in Hong Kong consisted mostly of revenue farms that focused on opium productions. The industry led to many wealthy Chinese businessmen, who established themselves as the middlemen merchants with international connection. Some of the successful farmers included Yan Wo Hong and Wo Hang Hong from 1858 to 1887. The system was discontinued by co ...

Sunset Industry
A sunset industry is an industry in decline, one that has passed its peak or boom periods. As one example, analogue recording technologies for audio or video have been supplanted by digital equivalents; although analogue equipment is still offered, sales have declined dramatically and are not expected to recover, so this segment of the market has been branded a 'sunset industry'. Many countries try to protect domestic sunset industries as they still provide important employment. They use protectionist policies to slow down the decline whilst sunrise industries develop.

Hectare
The hectare (; SI symbol: ha) is a non-SI metric unit of area equal to a square with 100-metre sides (1 hm2), that is, square metres (), and is primarily used in the measurement of land. There are 100 hectares in one square kilometre. An acre is about and one hectare contains about . In 1795, when the metric system was introduced, the ''are'' was defined as 100 square metres, or one square decametre, and the hectare (" hecto-" + "are") was thus 100 ''ares'' or km2 ( square metres). When the metric system was further rationalised in 1960, resulting in the International System of Units (), the ''are'' was not included as a recognised unit. The hectare, however, remains as a non-SI unit accepted for use with the SI and whose use is "expected to continue indefinitely". Though the dekare/decare daa () and are (100 m2) are not officially "accepted for use", they are still used in some contexts. Description The hectare (), although not a unit of SI, is ...

Amaranth
''Amaranthus'' is a cosmopolitan distribution, cosmopolitan group of more than 50 species which make up the genus of annual plant, annual or short-lived perennial plants collectively known as amaranths. Some names include "prostrate pigweed" and "Amaranthus caudatus, love lies bleeding". Some amaranth species are cultivated as leaf vegetables, pseudocereals, and ornamental plants. Catkin-like cymes of densely-packed flowers grow in summer or fall. Amaranth varies in flower, leaf, and stem color with a range of striking Plant pigments, pigments from the spectrum of maroon to crimson and can grow longitudinally from tall with a cylindrical, Succulent plant, succulent, fibrous stem that is hollow with grooves and bracteoles when mature. There are approximately 75 species in the genus, 10 of which are dioecious and native to North America, and the remaining 65 are monoecious species that are endemic to every continent (except Antarctica) from tropical lowlands to the Himalayas.

Water Spinach
''Ipomoea aquatica'', commonly known as water spinach or kangkung, is a semi- aquatic, tropical plant grown as a vegetable for its tender shoots. ''I. aquatica'' is generally believed to have been first domesticated in Southeast Asia. It is widely cultivated in Southeast Asia, East Asia, and South Asia. It grows abundantly near waterways and requires little to no care. Description ''Ipomoea aquatica'' grows in water or on moist soil. Its stems are or longer, rooting at the nodes. The hollow cavity within the stem makes the plant buoyant. The leaves vary from typically sagittate (arrowhead-shaped) to lanceolate, long and broad. The flowers are trumpet-shaped, in diameter, and usually white in colour with a mauve centre. Propagation is either by planting cuttings of the stem shoots, which will root along nodes, or by planting the seeds from flowers that produce seed pods. Names ''Ipomoea aquatica'' is most widely known as kangkong (also spelled ''kangkung''), its common name ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Yardlong Bean
The asparagus bean (''Vigna unguiculata'' subsp. ''sesquipedalis'') is a legume cultivated for its edible green pods containing immature seeds, like the green bean. It is also known as yardlong bean, pea bean, long-podded cowpea, Chinese long bean, snake bean, bodi, and bora. Despite the common name of "yardlong", the pods are actually only about half a yard long, so the subspecies name ''sesquipedalis'' (one-and-a-half-foot-long; ) is a more accurate approximation. A variety of the cowpea, the asparagus bean is grown primarily for its strikingly long () immature green pods and has uses very similar to those of the green bean. This plant is in a different genus from the common bean. The different colors of seeds usually distinguish the many varieties. It is a vigorous climbing annual vine. The plant is subtropical/tropical and most widely grown in the warmer parts of South Asia, Southeast Asia, and southern China. Cultivation The pods, which can begin to form after sowi ...

Matrimony Vine
''Lycium barbarum'' is a shrub native to China, with present-day range across Asia and southeast Europe. It is one of two species of boxthorn in the family Solanaceae from which the goji berry or wolfberry is harvested, the other being ''Lycium chinense''. Common names of the plant in English include Chinese wolfberry, barbary matrimony vine, red medlar or matrimony vine. In the United Kingdom it is also known as Duke of Argyll's tea tree after Archibald Campbell, 3rd Duke of Argyll who introduced it in the country in the 1730s. The shrub is an important commercial crop in northern China, especially in the Ningxia Hui Autonomous Region. Its Chinese name is ''Ningxia gǒuqǐ''.

Watercress
Watercress or yellowcress (''Nasturtium officinale'') is a species of aquatic flowering plant in the cabbage family, Brassicaceae. Watercress is a rapidly growing perennial plant native to Eurasia. It is one of the oldest known leaf vegetables consumed by humans. Watercress and many of its relatives, such as garden cress, mustard, radish, and wasabi, are noteworthy for their piquant flavors. Description Watercress can grow up to in length. The stems are hollow and float in water. The leaf structure is pinnately compound. Small, white, and green inflorescences are produced in clusters and are frequently visited by insects, especially hoverflies, such as '' Eristalis'' flies. Taxonomy Watercress is listed in some sources as belonging to the genus ''Rorippa'', although molecular evidence shows those aquatic species with hollow stems are more closely related to ''Cardamine'' than ''Rorippa''. Despite the Latin name, watercress is not particularly closely related to the fl ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Spinach
Spinach (''Spinacia oleracea'') is a leafy green flowering plant native to Central Asia, Central and Western Asia. It is of the order Caryophyllales, family Amaranthaceae, subfamily Chenopodioideae.

Chive
Chives, scientific name ''Allium schoenoprasum'', is a species of flowering plant in the family Amaryllidaceae. A perennial plant, ''A. schoenoprasum'' is widespread in nature across much of Eurasia and North America. It is the only species of ''Allium'' native to both the New world, New and the Old Worlds. The leaves and flowers are edible. Chives are a commonly used herb and vegetable with a variety of culinary uses. They are also used to repel insects. Description Chives are a bulb-forming herbaceous perennial plant, growing to tall. The bulbs are slender, conical, long and broad, and grow in dense clusters from the roots. The Scape (botany), scapes (or stems) are hollow and tubular, up to long and across, with a soft texture, although, prior to the emergence of a flower, they may appear stiffer than usual. The grass-like leaves, which are shorter than the scapes, are also hollow and tubular, or terete (round in cross-section). The flowers are pale purple, and ...

Spring Onion
Scallions (also known as green onions and spring onions) are edible vegetables of various species in the genus ''Allium''. Scallions generally have a milder taste than most onions. Their close relatives include garlic, shallots, leeks, chives, and Chinese onions. The leaves are eaten both raw and cooked. Scallions produce hollow, tubular, green leaves that grow directly from the bulb, which does not fully develop. This is different to other ''Allium'' species where bulbs fully develop, such as commercially available onions and garlic. With scallions, the leaves are what is typically chopped into various dishes and used as garnishes. Etymology and naming The names ''scallion'' and ''shallot'' derive from the Old French ''eschalotte'', by way of ''eschaloigne'', from the Latin ''Ascalōnia caepa'' or "Ascalonian onion", a namesake of the ancient Eastern Mediterranean coastal city of Ascalon. Other names used in various parts of the world include spring onion, green onion, t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mustard Plant
The mustard plant is any one of several plant species in the genera ''Brassica'', ''Rhamphospermum'' and ''Sinapis'' in the family Brassicaceae (the mustard family). Mustard seed is used as a spice. Grinding and mixing the seeds with water, vinegar, or other liquids creates the yellow condiment known as Mustard (condiment), prepared mustard. The seeds can also be pressed to make mustard oil, and the edible leaves can be eaten as Brassica juncea, mustard greens. Many vegetables are cultivated varieties of mustard plants; domestication may have begun 6,000 years ago. History Although some varieties of mustard plants were well-established crops in Hellenistic and Roman Empire, Roman times, Daniel Zohary, Zohary and Hopf note, "There are almost no Archaeology, archeological records available for any of these crops." Wild forms of mustard and its relatives, the radish and turnip, can be found over West Asia and Europe, suggesting their domestication took place somewhere in that ar ...

Radish
The radish (''Raphanus sativus'') is a flowering plant in the mustard family, Brassicaceae. Its large taproot is commonly used as a root vegetable, although the entire plant is edible and its leaves are sometimes used as a leaf vegetable. Originally domesticated in Asia, radishes are now grown and consumed globally. The radish is sometimes considered to form a species complex with the wild radish, and instead given the trinomial name ''Raphanus raphanistrum'' subsp. ''sativus''. Radishes are often used raw as a crunchy salad vegetable with a pungent, slightly spicy flavor, varying in intensity depending on its growing environment. There are numerous varieties varying in size, flavor, color, and length of time they take to mature. Radishes owe their sharp flavor to the various chemical compounds produced by the plants, including glucosinolate, myrosinase, and isothiocyanate. They are sometimes grown as companion plants and suffer from few pests and diseases. They germinate q ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
