Rice Production In China
Rice production in China is the amount of rice planted, grown, and harvested for consumption in the mainland of China. It is an important part of the national economy, where it is the world’s largest producer of rice, making up of 30% of global rice production. It produces the highest rice yields in Asia, at . Rice is produced throughout the nation and is believed to have been first domesticated in the surrounding regions of the Yangtze River and the Yunnan-Guizhou highlands of Southern China. Rice is believed to have been first cultivated around the Yangtze River Valley and Yellow River 11,000 years ago, found upon clustering in the middle of the Yangtze River in the provinces of Hubei and Hunan in central China according to archaeological records. The planting techniques of rice production in China encapsulates techniques such as water loss prevention such as turning soil into mud, and also seed transplantation. The main variants of rice produced and grown in China encapsul ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Oryza Sativa
''Oryza sativa'', commonly known as Asian rice or indica rice, is the plant species most commonly referred to in English as ''rice''. It is the type of farmed rice whose cultivars are most common globally, and was first domesticated in the Yangtze River basin in China 13,500 to 8,200 years ago. ''Oryza sativa'' belongs to the genus '' Oryza'' of the grass family Poaceae. With a genome consisting of 430 Mbp across 12 chromosomes, it is renowned for being easy to genetically modify and is a model organism for the botany of cereals. Classification ''Oryza sativa'' contains two major subspecies: the sticky, short-grained ''japonica'' or ''sinica'' variety, and the nonsticky, long-grained ' rice variety. ''Japonica'' was domesticated in the Yangtze Valley 9–6,000 years ago, and its varieties can be cultivated in dry fields (it is cultivated mainly submerged in Japan), in temperate East Asia, upland areas of Southeast Asia, and high elevations in South Asia, while ''indica'' ...

Natural Disaster
A natural disaster is "the negative impact following an actual occurrence of natural hazard in the event that it significantly harms a community". A natural disaster can cause loss of life or damage property, and typically leaves some economic damage in its wake. The severity of the damage depends on the affected population's resilience and on the infrastructure available. Examples of natural hazards include: avalanche, coastal flooding, cold wave, drought, earthquake, hail, heat wave, hurricane ( tropical cyclone), ice storm, landslide, lightning, riverine flooding, strong wind, tornado, typhoon, tsunami, volcanic activity, wildfire, winter weather. In modern times, the divide between natural, man-made and man-accelerated disasters is quite difficult to draw. Human choices and activities like architecture, fire, resource management or even climate change potentially play a role in causing "natural disasters". In fact, the term "natural disaster" has been calle ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Export
An export in international trade is a good produced in one country that is sold into another country or a service provided in one country for a national or resident of another country. The seller of such goods or the service provider is an ''exporter''; the foreign buyer is an ''importer''. Services that figure in international trade include financial, accounting and other professional services, tourism, education as well as intellectual property rights. Exportation of goods often requires the involvement of customs authorities. Firms Many manufacturing firms begin their global expansion as exporters and only later switch to another mode for serving a foreign market. Barriers There are four main types of export barriers: motivational, informational, operational/resource-based, and knowledge. Trade barriers are laws, regulations, policy, or practices that protect domestically made products from foreign competition. While restrictive business practices sometimes ...

Sowing
Sowing is the process of planting seeds. An area or object that has had seeds planted in it will be described as a sowed or sown area. Plants which are usually sown Among the major field crops, oats, wheat, and rye are sown, grasses and legumes are seeded and maize and soybeans are planted. In planting, wider rows (generally 75 cm (30 in) or more) are used, and the intent is to have precise; even spacing between individual seeds in the row, various mechanisms have been devised to count out individual seeds at exact intervals. Depth of sowing In sowing, little if any soil is placed over the seeds, as seeds can be generally sown into the soil by maintaining a planting depth of about 2-3 times the size of the seed. Sowing types and patterns For hand sowing, several sowing types exist; these include: * Flat sowing * Ridge sowing * Wide bed sowing Several patterns for sowing may be used together with these types; these include: * Regular rows * Rows that are ...

Cropping System
The term cropping system refers to the crops, crop sequences and management techniques used on a particular agricultural field over a period of years. It includes all spatial and temporal aspects of managing an agricultural system. Historically, cropping systems have been designed to maximise yield, but modern agriculture is increasingly concerned with promoting environmental sustainability in cropping systems. Crop choice Crop choice is central to any cropping system. In evaluating whether a given crop will be planted, a farmer must consider its profitability, adaptability to changing conditions, resistance to disease, and requirement for specific technologies during growth or harvesting. They must also consider the prevailing environmental conditions on their farm, and how the crop will fit in with other elements of their production system. Crop organisation and rotation Monoculture is the practice of growing a single crop in a given area, where polyculture involves growing ...

Hybrid Rice
Hybrid rice is a type of Asian rice that has been crossbred from two very different parent varieties. As with other types of hybrids, hybrid rice typically displays heterosis or "hybrid vigor", so when grown under the same conditions as comparable purebred rice varieties, it can produce up to 30% more yield.About hybrid rice from the .

Japonica Rice
Japonica rice (''Oryza sativa'' subsp. ''japonica''), sometimes called sinica rice, is one of the two major domestic types of Asian rice varieties. Japonica rice is extensively cultivated and consumed in East Asia, whereas in most other regions is the dominant type of rice. Japonica rice originated from Central China, where it was first domesticated along the Yangtze River basin approximately 9,500 to 6,000 years ago. Characteristics Japonica rice grains are rounder, thicker, and harder, compared to longer, thinner, and fluffier indica rice grains. Japonica rice is also stickier due to the higher content of amylopectin, whereas indica rice starch consists of less amylopectin and more amylose. Japonica rice plants are shorter than indica rice plants. Classification Japonica rice can be classified into three subgroups, 'temperate japonica', 'tropical japonica' (also known as 'javanica', ), and 'aromatic'. Temperate japonica is cultivated in East Asia (China, Japan, Korea, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Transplanting
In agriculture and gardening, transplanting or replanting is the technique of moving a plant from one location to another. Most often this takes the form of starting a plant from seed in optimal conditions, such as in a greenhouse or protected nursery bed, then replanting it in another, usually outdoor, growing location. The agricultural machine that does this is called a transplanter. This is common in market gardening and truck farming, where setting out or planting out are synonymous with transplanting. In the horticulture of some ornamental plants, transplants are used infrequently and carefully because they carry with them a significant risk of killing the plant.Basics of horticulture - Simson, Straus. Oxford Book Company, Edition 2010 Transplanting has a variety of applications, including: * Extending the growing season by starting plants indoors, before outdoor conditions are favorable; * Protecting young plants from diseases and pests until they are sufficiently estab ...

Yellow River
The Yellow River or Huang He (Chinese: , Mandarin: ''Huáng hé'' ) is the second-longest river in China, after the Yangtze River, and the sixth-longest river system in the world at the estimated length of . Originating in the Bayan Har Mountains in Qinghai province of Western China, it flows through nine provinces, and it empties into the Bohai Sea near the city of Dongying in Shandong province. The Yellow River basin has an east–west extent of about and a north–south extent of about . Its total drainage area is about . The Yellow River's basin was the birthplace of ancient Chinese, and, by extension, Far Eastern civilization, and it was the most prosperous region in early Chinese history. There are frequent devastating floods and course changes produced by the continual elevation of the river bed, sometimes above the level of its surrounding farm fields.

Agriculture
Agriculture or farming is the practice of cultivating plants and livestock. Agriculture was the key development in the rise of sedentary human civilization, whereby farming of domesticated species created food surpluses that enabled people to live in cities. The history of agriculture began thousands of years ago. After gathering wild grains beginning at least 105,000 years ago, nascent farmers began to plant them around 11,500 years ago. Sheep, goats, pigs and cattle were domesticated over 10,000 years ago. Plants were independently cultivated in at least 11 regions of the world. Industrial agriculture based on large-scale monoculture in the twentieth century came to dominate agricultural output, though about 2 billion people still depended on subsistence agriculture. The major agricultural products can be broadly grouped into foods, fibers, fuels, and raw materials (such as rubber). Food classes include cereals ( grains), vegetables, fruits, cooking oils, m ...
