1. According to research, China The earliest and most primitive commodity trade in ancient times was grain trade, which originated from the prosperity of matrilineal clans or the beginning of patrilineal clans in primitive society. It is said that Emperor Yan Shennong "made thunder to teach people how to farm" and then "farmed and made pottery". The tribe headed by Shennong mainly focused on agriculture, and the handicraft industry had a certain development, so there was a certain surplus of products and a certain social division of labor, which led to the exchange of commodities such as grain and pottery. The so-called "Kimchi is not made, Shen Nong makes it, goes on the market, the sun makes the market, creates the people of the world, collects the goods of the world, trades retreat, each has its own strengths" refers to this primitive grain and food trade, or the trade of other products
2. Grain output refers to the total amount of grain produced by agricultural producers and operators in a calendar year. According to the harvest season, it includes summer grain, early rice and autumn grain; according to the crop variety, it includes cereals, potatoes and beans.
Yield calculation method: after threshing, it is calculated as raw grain, and after depoding, it is calculated as dry beans; before 1963, potatoes (including sweet potatoes and potatoes, excluding taro and cassava) were calculated as 1 kg of fresh potatoes for every 4 kg Grain calculations. Since 1964, it has been calculated as 5 kg of fresh potatoes per 1 kg of cereals; potatoes as suburban vegetables (such as potatoes) are calculated as fresh products and no cereal statistics are carried out. Before 1989, national grain output data were mainly obtained through comprehensive reports. In 1989, sample survey data were used.
In 2020, China's total grain output will reach 669.49 million tons, an increase of 0.9% from 2019, an increase of 5.65 million tons
In 2021, China's total summer grain output will reach 145.82 million tons , an increase of 2.1% compared with 2020
3. In addition to rice, wheat, corn, sorghum, millet and other miscellaneous grains, grains also include potatoes and beans. The yield calculation method is that beans are calculated as dry beans after removing the pods; potatoes (including sweet potatoes and potatoes, excluding taro and cassava) are calculated as 1 kg of grain for every 4 kg of fresh potatoes before 1963. This change began in 1964. It is calculated based on 5 kilograms of fresh potatoes divided into 1 kilogram of grain. Tubes (such as potatoes, etc.) used as vegetables in urban suburbs are counted as fresh products and are not included in grain statistics. All other grains are calculated as raw grains after threshing. Before 1989, national grain output data were mainly obtained through comprehensive reports. In 1989, sample survey data began to be used.
