摘 要 ：安徽省芒属植物有3种量变种:五节芒(Miscanthus floridulus)、芒(M.sinensis var. sinensis)、紫芒(M. sinensis var. purpurascens)和荻(M. saccharifl-orus);其中紫芒为本省地理分布新记录。它们的资源量大;如全省仅连片五节芒草地即达260多万亩,一般亩产鲜草1000—2500公斤。芒属植物是利用价值很高的资源禾草:饲用价值“良等”;保持水土能力强;纤维品质优良,为制浆造纸及编织的上等原料;并可药用。最后,提出了开发利用芒属植物资源的几点建议。
Abstract:According to investigation, there are 3 species and 1 variety of the genus Miscanthus in Anhui Province: Miscanthus floridulus, M. sinensis var. sinensis, M. sinensis var. purpurascens and M. savchariflorus; In order to distinguish conveniently, a key to the species has been compiled in this paper. In Anhui, the quanta of spontaneous resources of them is very abundant, M. floridulus-M. sinensis is edificator of the altoherbosa in various grasslands, and M. sacchariflorus Formation is one of the main emer iherbosas. The area of the grassland of M. floridulus, such as, is more than 173340 ha, and the fresh yield per ha is usually 15—37.5t. All of the plants are very worthy perennial resource grasses: good forage plant, first-rate plant of the soil conservation, high-class raw material of papermaking and herbal medicines. Several suggestions of exploitation and utilization of plant resources of the genus Miscanthus has been proposed in this paper.
