沙芦草(Agropyron mongolicum Keng)又名蒙古冰草,原产于我国北部沙漠以南边缘地带,内蒙古、山西西北部、陕西北部、宁夏、甘肃均有分布,并在局部地区为建群种或优势种。因其抗性强、品质优,是我国荒漠草原区的优良多年生禾草种之一,近年来在进行人工栽培驯化的同时,已被广泛用来补播改良天然草地。为了充分认识和利用这一牧草资源,我们多年来结合栽培驯化对其生物学及经济学特性进行了研究。 Agropyron mongolicum Keng, also known as Mongolian snowgrass, is native to the southern margin of the northern desert in China. Inner Mongolia, northwestern Shanxi, northern Shaanxi, Ningxia and Gansu are distributed in some areas, Dominant species. Due to its strong resistance and excellent quality, it is one of the fine perennial grasses in the desert steppe region. In recent years, artificial grass domestication and domestication have been widely used to supplement natural grassland. In order to fully understand and utilize this forage resource, we have studied its biological and economic characteristics for many years in combination with cultivation and domestication.
