Asian foxtail (Uraria crinita) profile

Asian Foxtail is native to the temperate zone of Europe and Asia. Asian foxtail is cultivated in all countries of Europe and America. It was listed as an important forage grass in the former Soviet Union. China's northeast, north, northwest provinces are planted, but the area is small. Asian foxtail is of high feeding value. But it has not been widely adopted. In 1978, the Grassland Task Force of Gansu Province, together with the Minshan Breeding Farm and some forage experts, conducted a comprehensive survey of the pastures, and confirmed that Asian Foxtail was an excellent forage suitable for cultivation. Then organize strength, expand cultivation, propagation and promotion.

The stem is erect, internodes are short, 6-7 nodes, lower nodes are more oblique, base 1 ~ 2 nodes are more developed, swelling is spherical. Leaf blade of Asian foxtail is flat slender, smooth glabrous, sharp tip, 10 ~ 30 cm long, 0.3 ~ 0.8 cm wide, leaf sheath loose embrace stem, longer than internode; Ligule is triangular; The auricle is round. Panicles, spikelets compact, columnar, 5 -- 10 cm long; Each spikelet has only one flower. The glume of Asian foxtail is round with a keel, with fuzz on the edge and short awn on the front end; Lemma half of the glume, apical apiculate; Palea is narrow, slightly shorter than lemma. Seeds of Asian foxtail are small, nearly round, easily separated from the glume. A thousand grains weigh only 0.36 grams.

The leaves of Asian foxtail are odd pinnately compound, the lower leaflet of the stem is usually 3, the upper leaflet is 5, rarely 7; Stipules are long triangular, 6-10 mm long, apex slender and acute, base 2 mm wide, margin grayish-white ciliate; Petiole of Asian foxtail is 5.5 -- 15 cm long, gray-white pubescent; Lobular is nearly leathery, oblong, ovoid, lanceolate or ovate, apex lobular 6-15 cm long, 3-8 cm wide, lateral lobule slightly smaller, apex slightly acute, obtuse or rounded, base rounded to slightly cordate, glabrous or above on the midrib slightly gray pubescent, below pubescent along veins, lateral veins 6-9 per side, in the two sides are raised, the following net vein; Stipules of Asian foxtail are narrowly triangular, 5 mm long, 1.5 mm wide at base, sparsely ciliate;Petioles 1-3 mm long, densely pilose.

Racemes of Asian foxtail are terminal, 15-30 cm or longer, stout, densely covered with gray-white hirsute; Bracts are ovate or lanceolate, up to 2 cm wide to 7 mm, striate, white with ciliate hairs; Pedicels ca. are 4 mm, elongating to 10 -- 15 mm after anthesis, curved, covered with short hooked and long white hairs; Calyx of Asian foxtail is shallowly cup-shaped, white hirsute, 5-lobed, upper 2-lobed ca. 3 mm, lower 3-lobed 3.5 mm; Corolla is purple, 6 mm long.

Pod of Asian foxtail is slightly pubescent; Pod nodes 2-4, elliptic, reticulate. 

The ecological habits of Asian foxtail

Asian foxtail mostly grows on the slopes of dry wilderness, along roads or in thickets, at an altitude below 850 meters.

Asian foxtails are fond of cold, cool and humid climates and have strong cold resistance. They can safely overwinter in Northeast China, and the overwintering rate is also high in areas with irrigation conditions in Inner Mongolia and Xinjiang. The optimum growth temperature is 16 ~ 21℃.Sensitive to drought and high temperature, not adapted to drought in northwest China (except in areas with irrigation conditions) and summer high temperature in low altitude areas of south China. Asian Foxtail likes moisture and is tolerant to water flooding. It is not strict with soil. Asian foxtail can adapt to various types of soil. Asian Foxtail has a long growth year, usually 6 ~ 7 years, and can be managed for 10 ~ 15 years.

The purpose of Asian foxtail

Asian foxtail is suitable for cutting green feed, silage or hay preparation. Asian foxtail can not tolerate livestock trampling, too much grazing use will shorten its life. However, the grassland mixed with alfalfa and red clover can still be used for short-term grazing.

Asian Foxtail is coarse in grass, but it still has high nutritional value and palatability. It is most suitable for mowing and making hay, and is an excellent forage for mules, horses and cattle, but not for sheep. It can be mowed 2 ~ 3 times a year in the northern humid area, and the yield of fresh grass is 3000 ~ 4000 kg per 667 square meters (1 acre). When mowing, the stubble height should be kept at 10 ~ 12 cm.
