Abstract: In order to study the effects of different fertilizer levels and different fertilization methods on forage yield and forage quality of forage ramie, two ways of fertilizing compound fertilizer and two ways of topdressing urea were used. Through combination of different fertilizer levels of urea and compound fertilizer, eight fertilization treatments were set up. The results showed that when the application of compound fertilizer was conducted once as basal fertilizer at 0.054 kg/m2, and topdressing urea once every harvest at 0.006 kg/m2, agronomic traits were the best with the ramet number being 42.00 strains each stump, the ratio of leaf and stem being 2.04 and the ratio of dry and fresh weight being 0.15. When the application of compound fertilizer was conducted once as basal fertilizer at 0.108 kg/m2, and topdressing urea once every harvest at 0.0135 kg/m2, forage yield was 17.07 kg/m2, which was significantly better than that of other treatments. In terms of forage quality, content of crude protein in three treatments (compound fertilizer applied once as basal fertilizer at 0.108 kg/m2, and topdressing urea applied once every harvest at 0.0135 kg/m2; compound fertilizer applied twice as basal fertilizer at 0.054 kg/m2, and topdressing urea applied once every harvest at 0.0135 kg/m2; compound fertilizer applied once as basal fertilizer at 0.054 kg/m2, and topdressing urea applied once every harvest at 0.006 kg/m2) were significantly better than that in other treatments. This study provided a reference for improving forage ramie cultivation and management technologies.
