Highland barley is a cereal crop, which is suitable for growing in the cool climate of plateau. Because the inner and outer glumes are separated and the seeds are bare, it is also called naked barley, yuan wheat and rice wheat. The three stems are upright and smooth, with a height of about 100 cm, a diameter of 4-6 mm and 4-5 nodes. The leaf sheath is smooth, shorter than the base or longer than the internodes, with two lobes on both sides, embracing each other. The ligule is membranous, with a length of 1-2 mm, a leaf length of 9-20 cm and a width of 8- 15 mm, which is slightly rough.
Spikes are yellow-brown or purple-brown, 4-8 cm long (except awn), 1.8-2 cm wide, and spikelets are about 1 cm long. Glumes are linear-lanceolate, short-haired, awn-shaped at the top, and 1 cm long, and the top of lemma extends to 10 cm long.
Introduction of growth habits of highland barley;
Highland barley is a highly adaptable crop, which has strong adaptability to cold and barren. Generally, it is sown in March-May and harvested in July-September, so it is called spring naked barley in the history of cultivation. The general production period is 100- 130 days, and the seedling stage can withstand the low temperature of-10℃. When the flowering period is 9℃, it will not be hurt. It can still resist the low temperature of-1℃ in the milk ripening stage. In the alpine region, the average temperature in the warmest month is close to 10℃, and the days when the average daily temperature is higher than 5℃ are only 120 days, highland barley can still grow and develop normally.
Growth conditions of highland barley: moderate temperature in spring, windy and snowy; In summer, the climate is mild and the light is sufficient; In autumn, the weather is crisp, windy and rainy, and the temperature is moderate. Winter is cold and dry. The annual average temperature is 65438 0.5℃, the annual frost-free period is about 60 days, and the annual sunshine hours are more than 3200 hours.
