Effects of grazing and light on productivity of artificial pasture of understory

Effects of grazing intensity (0 goat/ha,22.2 goats/ha and 44.4 goats/ha) and light conditions (100%,68.83% and 54.29% light intensity) on productivity of mixedsown artificial grassland under Cinnamomum camphora forest were studied. The results showed, during the whole growth seasons, standing crop, regrowth biomass and net primary production of artificial grassland all increased as light intensity increased at the same grazing rate, and there was a tendency of 22.2 goats/ha0 goat/ha44.4 goats/ha at the same light intensity. The results implied that moderate grazing density could promote growth of grass and increase productivity of grassland, furthermore, moderate weak light condition would not decrease productivity seriously in C.camphora grasses goats system. Thus, its possible to develop silvipastoral system for local area.
