The effects of simulated spring goose grazing on the growth rate and protein content of Phleum pratense leaves.

摘要: The effects of simulated goose grazing on Phleum pratense plants were tested in an Iceland hayfield during the spring staging period (19 April–11 May 1997). Plants area exclosed from influence and nutrient faeces subject to removal youngest lamina once, three four times this period. Clipping resulted 25–41% increases cumulative elongation laminae compared with unclipped plants. Total growth entire showed no significant difference between those clipped times, hence overcompensation occurred. Sequential clipping elevated protein content 20% 27–33%, whereas there was change amongst shoots only once. Because geese consume each plant, measurements experiment that regular physical growing biomass doubled preferred tissue available increased potential intake 3.5 at experimental frequencies similar levels sequential harvesting observed less frequent harvesting. These achieved without any fertilising implicated such previous studies.
