The fibrous roots are tough. The culm is erect, smooth and hairless, with a height of 120 cm and knots. The leaf sheath is loose, the tongue is transparent and membranous, the leaves are flat and slightly rough, the panicles are flat and pyramidal, and the spikelets contain small flowers; Spikelet axis is nearly hairless or sparsely short hair, which is not easy to break; The back of the first lemma is hairless, the basal disc has only a few short hairs or nearly hairless awns, or only the back has 1 straight awns, and the second lemma is hairless and usually awnless. Lilac is light brown pilose, with longitudinal grooves on its ventral surface, and it blooms and bears fruit from April to September.

Oat is a worldwide cultivated crop. However, the main concentrated producing areas are temperate regions in the northern hemisphere. The main producers are Russian, Canadian, American, Australian, German, Finland and China. The main producing areas of oats in China are Inner Mongolia, Hebei, Jilin, Shanxi, Shaanxi, Qinghai and Gansu, with small areas planted in Yunnan, Guizhou, Sichuan and Tibet, among which Inner Mongolia has the largest planting area. I like the cold and dry climate.

Oat grains are used for grinding or as feed, and have high nutritional value.

morphological character

Panicum miliaceum [2]. The fibrous roots are tough. The stem is erect, smooth and hairless, 60- 120 cm high, with 2-4 nodes. Leaf sheaths are loose, smooth or hairy at the base; Ligule transparent membrane, length 1-5 mm; The leaf blade is flat, with a length of 10-30 cm and a width of 4- 12 mm, slightly rough and sparsely hairy on the upper surface and edge.

Panicle spreading, pyramid-shaped, 10-25 cm long, with angular and rough branches; Spikelet length 18-25mm, containing 2-3 florets, with bent and drooping stems and swollen tips. [3] Spikelets contain 1-2 florets; Spikelet axis is nearly hairless or sparsely short hair, which is not easy to break; The back of the first lemma is hairless, the basal disc has only a few short hairs or nearly hairless awns, or only the back has 1 straight awns, and the second lemma is hairless and usually awnless. [4] Dianthus is light brown pilose, with longitudinal grooves on the ventral side and 6-8 mm long. The flowering and fruiting period is from April to September. [3]

principal item

Generally, it can be divided into two categories: naked oats and naked oats. [5]

growing environment

The growing environment of oats is different from ordinary grains, and it likes cold and dry climate. The northern foot of Yinshan Mountain in the middle of Inner Mongolia Autonomous Region in China is known as the main producing area of golden oats in the world. The altitude is about 2000 meters, the annual sunshine time is more than 3000 hours, the temperature difference between day and night is large, and the monsoon with an average of 3 meters per second blows all the year round.
