rdf:langString 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 6.5 metric tons per hectare (2.6 long ton/acre; 2.9 short ton/acre). 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 encapsulates wild rice species of O. Mereriana, O. Officinalis and O. Rufipogon and the main Chinese cultivated rice varieties are indica and japonica subspecies, with ongoing developments of rice breeding in hybrid rice established by the Ministry of Agriculture in China. The subspecies of the Indica and Japonica rice are produced in different, and some in overlapping regions across China, with the hybrid rice predominantly growing in the region of Central China. There are many geographical regions across China for rice production. The geographical setting in the rice production regions across China highlights different climates (subtropical, cold, and dry), growing periods and soils which is what makes the rice varieties distinct from one another. The geographical setting is what delineates the different planting and harvesting seasons of rice variants in the regions. Rice production in China is labour-intensive, and is dependent on a variety of cropping and planting methods. The processes of production in cropping systems vary across the regions of China due to the differences in climate in each growing region. The predominant processes of rice production in planting methods that are in use in China includes, transplanting, manual transplanting, mechanical transplanting, throwing seeding, direct seeding, as well as rice ratooning. Under differences and changes in the selection of rice varieties and cultivation techniques under various planting methods, this highlights the differences in terms of rice quality. Due to changes in recent decades in all aspects, this has led to the changes in planting areas across China for rice production. In terms of exports, China has exported 4.56% of the world’s rice in 2019, with a value of US$1.13 billion. As of 2020/2021, it is the sixth principal rice exporter in the world behind India, Vietnam, Thailand, Pakistan and the United States. The rice production in China over recent years has faced challenges. These challenges encapsulates climate change that has brought increased frequencies of natural disasters, overuse of fertilisers that leads to a decline in the fertility of land, as well as, overuse of pesticides that promotes changes in biodiversity leading to increased pest outbreaks. The future of rice production in China is one that encapsulates elite germaplasm, genetic diversity, and the super rice breeding programs to promote tolerance to the current challenges. The future prospects of integrated rice cultivation systems is to be further developed in assistance of current agricultural systems and databases to manage current challenges. Moreover, lowering water-usage is also a future prospect to be delved into. Rice is highly prized by consumers as a food grain, making it a staple food for two-thirds of the nation. Produced rice grains that have numerous flavours, textures, and grains, each with unique differentiating forms and distinct qualities can be made into a variety of foods that are prominent in China. Out of all, one type that is renowned across the world is cooked rice, which can encapsulate both rice porridge and fried rice. Rice grained and ground can be made into noodles. Glutinous sticky rice is also a form of rice that can be turned into a variety of dishes and desserts, as well as including alcoholic beverages and rice brans.
