Summary

柳枝稷是本土植物, warm-season, 常年, tall grass that reproduces from seed and rhizomes. Switchgrass is categorized as either upland or lowland.  Upland types are typically shorter and generally found on upland sites with lower fertility and drier conditions. Lowland types can reach 8 to 10 feet tall, 非常健壮, and found in moister low areas with high fertility. Mature lowland types will tolerate long periods of flooding. Switchgrass is a very persistent species with excellent drought hardiness and cold tolerance. Switchgrass is widely adapted and found throughout the United States with the exception of the West Coast. Switchgrass produces large seeds on a spangled-type seed head. The stem is round, hollow, and usually has a reddish tint. Switchgrass is easily identified by a small nest of hair where the blades attach to the sheath. Switchgrass is used for pasture and makes a good quality hay when mowed prior to seedhead formation. It should not be grazed closer than 5 to 7 inches during the growing season. In recent years interest in biofuel research has generated substantial interest in developing new varieties of Switchgrass as well as new management strategies.  用于保护和牧场使用, Switchgrass is usually seeded in mixtures with Bluestem, Indiangrass, 和Sideoats格拉玛. 阿拉莫 was originally collected in far south-central Texas on the banks of the Frio River near George West. The Plant Materials Center near Knox City, Texas selected and released 阿拉莫 as an improved variety based on superior forage yield, 种子生产, 提高秧苗活力. 阿拉莫 is primarily adapted to regions south of I-70 which intersects Kansas east to west.  阿拉莫 performs best in areas of 25 inches of annual precipitation or when planted in low lying areas in arid climates. 阿拉莫, with good moisture and soil fertility, can reach heights up to 10 feet and produce in excess in of 7 tons of biomass annually.  阿拉莫 performs well on a wide range of soils from clay to very fine sand.  Recommended seeding rates range from 4 to 6 Pure Live Seed pounds per acre.
