Classification and alias of Gramineae and Agropyron. The aliases are Agropyron cristatum, crested grass, wild wheat grass, wheat grass, wheat grass, barley grass, mountain wheat grass, feather wheat grass and goatee.

Geographical distribution is widely distributed in temperate grassland and desert grassland areas, and in the former Soviet Union, Mongolia and the three northern and southwestern regions of China on the Eurasian Plateau.

The biological and ecological characteristics are xerophytes with strong drought resistance and cold tolerance. It overwinters well at-4 ~-48℃. Suitable for dry and cold areas. Barren-tolerant, suitable for sandy soil, arid loess hills and sandy wasteland, especially on chestnut soil in dry grassland. It can also grow on clay soil. Salt-alkali tolerance, no tolerance to wet and waterlogging, rare in acidic and humid environment. It is common on dry land such as flat hills and slopes in grassland areas. It is a long-lived forage grass, with a life span of more than 1 years and strong tillering ability, and soon forms a plant cluster. But the regeneration ability is poor, only once, and then grazing. Seeds can naturally fall to the ground and be spontaneous. The seeds are full, the germination rate is high, and the seedlings emerge quickly and neatly. The growth period is 11 ~ 12 days, with early turning green, late yellowing and long green period.

cultivation techniques: 1-grain weight is 2g. It can be planted in spring, summer and autumn, mainly depending on the soil moisture. It is advisable to collect seeds and sow them from late July to early August. The amount of drill sowing is 15 ~ 22.5 kg/ha, the row spacing is 3 ~ 4 cm, the soil is 2 ~ 3 cm, and it can also be sown. Seedling growth is extremely slow, and it can also be mixed with leguminous grass such as alfalfa.

Economic value Agropyron cristatum is an excellent forage grass with soft quality and high nutritional value. Mixed sowing with alfalfa has a good effect, which can improve soil and increase fertilizer, and obtain high yield and high quality forage grass. Because the plants are low and the upper leaves are few, it is suitable for grazing.
