How much corn is grown in China?

Among the three main grain crops of rice, wheat, and corn in China, corn has the largest planting area.

In 2020, among the grain crops planted in China, the planting area of rice was 30.08 million hectares, an increase of 380,000 hectares over the previous year, accounting for about the total grain planting area; The sown area of wheat was 23.38 million hectares, a decrease of 350,000 hectares over the previous year, accounting for about 20 percent of the total grain planting area; The planting area of maize was 41.26 million hectares, a decrease of 20,000 hectares over the previous year, accounting for about the total grain planting area. In 2020, China's annual grain output was 669.49 million tons, an increase of 5.65 million tons over the previous year, of which 142.86 million tons were summer grain, 27.29 million tons of early rice, and 499.34 million tons of autumn grain.

As a food crop, corn is native to Central and South America, and it has strong drought tolerance, cold tolerance, barrenness tolerance and excellent environmental adaptability. The history of corn cultivation in our country is not very long, about after Columbus discovered the American continent, that is, in the 16th century, it was introduced to China, and it has been planted for nearly 500 years now. However, with the super adaptability of corn to the environment, as well as the diversity of uses, corn is currently one of the important feeds in the aquaculture industry, so the planting of corn in China is very extensive, and it is planted in all parts of the north and south of China, and in general, the northern region is the main production area of corn planting.

I think corn is generally grown on a large scale in Shanxi, Henan, Hebei, Liaoning and Heilongjiang.

The planting scale in the northern region is relatively large, mainly concentrated in Henan, Hebei, Shanxi, Inner Mongolia, Heilongjiang and other places, the planting area is very large, and the quality is also very high.

Summary. China's maize cultivation is mainly concentrated in four main producing areas, including the spring-sown maize area in the northeast and north regions, the summer-sown maize area in the Huanghuaihai region, the maize region in the northwest and the maize region in the southwest.

The cultivation of Yujiaying rice in Zhongling is mainly concentrated in four main producing areas, including the spring sowing corn area in North East China, the summer sowing corn area in Huanghuaihai, the northwest corn area and the southwest corn area.

The top three provinces and cities in China's corn production are Heilongjiang Province, Jilin Province and Inner Mongolia Autonomous Region.

The planting areas mainly include Heilongjiang, Jilin, Liaoning, Inner Mongolia Yuqing Tanmi planting area, Shaanxi and central Shanxi Province, northern Hebei corn planting area. This area is a high-yield corn area in China, and the corn planting area accounts for 40% of the national corn area, which is the largest corn planting area in China.

The summer sowing corn area of the Huang-Huai-Hai Plain is a plain formed by the common alluvium of the Yellow River, the Huai River and the Haihe River, and is the abbreviation of the plain of the Yellow River, Huai River and Haihe River basins. The terrain of the area is flat, with an altitude of less than 50 meters. The scope of administrative division roughly includes all the three provinces and cities of Beijing, Tianjin and Shandong, most of Hebei and Henan provinces, and the northern region of Jiangsu and Anhui provinces, with a total jurisdiction of 53 prefectures and cities, 376 counties (cities and districts), and the total land area of the whole region is square kilometers.

The Huanghuaihai summer sowing corn area is located in the middle of China's corn belt, including the whole territory of Henan and Shandong, the central and southern parts of Hebei Province, the Guanzhong and southern Shaanxi regions of Shaanxi Province, the southern part of Shanxi Province, Anhui and Jiangsu Province, and the annual corn planting area accounts for about 35% of the country, which is one of the two dominant producing areas in China.

Okay, thanks!

Okay dear!

Hello, the varieties of corn in China are probably as follows, for your reference only: corn can be divided into 9 types according to the grain form and structure: hard grain type, horse tooth type, powder type, sweet type, sweet powder type, burst type, waxy type, barley type, and semi-horse tooth type.

Around the middle of the 16th century, corn came to China and began to be cultivated in China. The earliest record is found in the "Gongxian Chronicles" written in the 34th year of Jiajing in the Ming Dynasty, calling it "Yumai", and then in the 39th year of Jiajing, "Pingliangfu Chronicles" called "Fanmai" and "Xitianmai". The name "corn" was first seen in Xu Guangqi's "Complete Book of Agricultural Administration".

By the end of the Ming Dynasty, the planting of corn in China has reached more than ten provinces, Jilin, Zhejiang, Fujian, Yunnan, Guangdong, Guangxi, Guizhou, Sichuan, Shaanxi, Gansu, Shandong, Henan, Hebei, Anhui and other places. But don't look at so many places to grow, corn finch acacia was still regarded as a rare thing at that time, and in the Qianlong period of the Qing Dynasty, corn was still a royal thing, which was provided by the Ministry of Internal Affairs full-time.

Corn is the seed of the grass herbaceous maize, native to Mexico and Peru in Latin America along the foothills of the Andes. In 1492, Columbus discovered corn in Cuba, and in 1499 he brought it back to Spain. Later, with the development of the world's maritime industry, corn had the opportunity to gradually spread to all parts of the world.

Today, with the exception of the Americas, which is the place of origin, China is one of the most popular regions for corn cultivation.
