Why Wuchuan, Inner Mongolia is the hometown of oats?

Oat is an ancient crop. According to historical records, as the hometown of naked oats, China has been planting naked oats for more than 2,500 years. It is widely planted in mountainous areas, plateaus and cold areas in northern China, mainly distributed in Inner Mongolia, Hebei, Henan, Shanxi, Gansu, Shaanxi, Yunnan, Sichuan, Ningxia, Guizhou and Qinghai provinces.

Naked oats first originated in the yinshan mountains, Inner Mongolia, on the southern edge of the Mongolian Plateau, and later gradually became one of the main food crops in the alpine region of northern China. The northern foot of Yinshan Mountain, represented by Wuchuan County, is the origin of naked oats in the world, commonly known as "Houshan" area.

Wuchuan County is located at the geographic latitude of 465438+0-43 north latitude, in the middle of Inner Mongolia Autonomous Region, at the northern foot of Yinshan Mountain and in the north of Hohhot. It is known as the back garden of the capital of the autonomous region, and the latitude of 465438+0-43 north latitude is also recognized as the golden growth latitude of naked oats in the world. The unique quality of oats in Wuchuan depends on the climatic conditions and geographical advantages of natural cultivation and land cultivation. As far as climatic conditions are concerned, oats are long-day crops, which like to be cool but not cold-resistant, and avoid high temperature and dryness. The accumulated temperature needed in the growing period is low, but it is not suitable for cold climate. The climate characteristics of Wuchuan are highly matched: sunshine 16 hours/day, average temperature 3℃/ year, frost-free period 124 days/year, large temperature difference between day and night in four seasons, and large transpiration coefficient of oats.

The contents of protein, calcium, phosphorus, iron, riboflavin and other nutrients in Wuchuan oat cultivated in natural environment are higher than other crops, and the proportion of amino acids is balanced, especially the content of lysine is high, accounting for 37% of the total protein, which is significantly higher than that of wheat and corn. Linoleic acid content in fat accounts for 38.5%-45.3% of the total unsaturated fatty acids, which is about twice that of peanut oil. These characteristics make Wuchuan oats taste good and have a strong flavor. In addition, it is of great benefit to human body-linoleic acid and fatty acid in oats have certain preventive and therapeutic effects on various diseases caused by atherosclerosis, and regular consumption of oats has a good effect on lowering blood lipid, preventing and treating arteriosclerosis and heart disease caused by it, so Wuchuan oats are famous far and wide.
