扁穗牛鞭草[Hemal thria compressa(L.f.)R.Br]。俗称马鞭稍,扁担草。是禾本科牛鞭草属的多年生牧草。该草在我国云南,两广山地广有分布。经过栽培驯化,扁穗牛鞭草具有适应广,抗逆性强,含养分丰富,成本低廉等优点。在日平均温16.8℃,年降雨量1501毫米,海拔高516米的四川洪雅县阳坪草坡种植,从1980年至1983年连续四年的试验观察和100亩以上大面积种植利用的结果:一般亩产达0.85—1.5万公斤,个别高产地达1.5万公斤以上。 一、生物学特性: 扁穗牛鞭草是疏丛状禾本科牧草。根系发达,入土深达1.5米,一般集中分布在30厘米土层内。单株稀植呈半匍匐型,茎杆横卧地面逐渐向上倾斜;群体密度加大,株丛趋向直立。茎一般高130—150厘米,最长可达3米,茎具有节10—26个,茎杆表面具有一层很厚的腊质。叶片狭长形,无毛,色深绿,一般长1.5—20厘米,宽5—8毫米。总状花序细弱,单生于茎顶,长5—10厘米,宽约2—3毫
Hemispermum companion [Hemal thria compressa (L.f.) R.Br]. Commonly known as whip slightly, pole grass. It is a perennial pasture of the genus Verbena. The grass in our country Yunnan, Guangdong and Guangxi widely distributed. After cultivation and acclimation, Hemarthria sphaerocephala has a wide adaptability, strong resistance, nutrient-rich, low cost and so on. In the average daily temperature of 16.8 ℃, the annual rainfall of 1501 mm, 516 meters above sea level in Hong Yangxian County, Sichuan Yangping grass slope cultivation, from 1980 to 1983 for four consecutive years of experimental observation and more than 100 acres of large-scale planting and utilization results : General mu produce up to 0.85-1.5 million kilograms, individual high-yielding area amounts to more than 15,000 kilograms. First, the biological characteristics: Hemispiphone Hepulaceae is a poor grassland grasses. Developed roots, deep into the soil up to 1.5 meters, generally concentrated in 30 cm soil layer. The plantlets were semi-creeping and the tilted stem tilted upward gradually. The population density increased and the plantlets tended to erect. Stems generally 130-150 cm high, up to 3 meters, stems with sections 10-26, the stem surface has a thick layer of waxy. Leaf blade elongated, glabrous, dark green, usually 1.5-20 cm long, 5-8 mm wide. Raceme delicate, solitary in the stem top, 5-10 cm long, about 2-3 millimeters wide
