| 摘 要： | 研究了不同放牧强度G0(0只/hm2)、G1(22.2 只/hm2)、G2(44.4只/hm2)和不同光照条件(100%光强、68.83%光强和54.29%光强)对香樟(Cinnamomum camphora)林下混播草地生产力的影响.结果显示,在整个生长季,草地现存量、再生量和净初级生产力在同一放牧强度下均呈现随光照...

| Abstract: | 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/ha>0 goat/ha>44.4 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,it’s possible to develop silvipastoral system for local area. |
