Effect of nitrogen fertiliser application on cell wall composition in switchgrass and reed canary grass

摘要: Abstract Dry matter yields of two energy grass crop species grown on low productivity arable land in South East England were significantly increased by application nitrogen fertiliser (switchgrass, yield increase 43% with 100 kg ha −1  N; reed canary grass, 87% 150 kg ha  N). Furthermore, N at these concentrations had significant effects cell wall composition. Growth year and time harvest also The effect was greater which showed small but increases neutral detergent fibre cellulose content (increases 3.5% 7.5% respectively compared plots not treated N). Both Klason lignin (an 10.0% 4.4% switchgrass Analysis acid rate. We discuss the implications changes feedstock utility degree to may be offset decreased utility.
