Oats (Avena sativa? Annual herb. The leaf sheaths are loose, the ligules are transparent and membranous, the leaves are flat and slightly rough, the panicles are unfolded, pyramid-shaped, and the spikelets contain small flowers. The panicles are spreading, pyramid-shaped, 10-25 cm long, with angular and rough branches.

The caryopses are covered with light brown pubescence and have longitudinal grooves on their abdomen. They bloom and bear fruit from April to September. Oats are recorded in "Compendium of Materia Medica": "Oats are mostly wild and are eaten by chaffinches, hence the name."

The main production areas of oats are the temperate regions of the northern hemisphere. The main oat-producing areas in China include Inner Mongolia, Hebei and Gansu. Yunnan, Guizhou, Sichuan and Tibet have small areas of cultivation. Among them, Inner Mongolia has the largest planting area, accounting for more than 35% of the total oat planting area in China.

Oats like coolness, humidity, sunshine, and are intolerant to high temperatures. Insufficient light will cause stunting. They are generally sown and planted in cold and dry lands in mountainous areas such as Chuandi, Pingjuewudi, Liangdi, and gentle slopes. .

Oatmeal has a significant effect in lowering low-density cholesterol, and also has a certain effect in increasing serum high-density cholesterol. The effect of lowering blood lipids is very obvious. Oats are also widely used in other industries, such as the cosmetics and pharmaceutical industries.

The northern foothills of the Yinshan Mountains in the central Inner Mongolia Autonomous Region of China are known as the main producing areas of golden oats in the world. The altitude here is about 2,000 meters. The annual sunshine time exceeds 3,000 hours, the temperature difference between day and night is large, and the monsoon with an average of 3 meters/second blows all year round.
