摘要：The productivity of eucalypt plantations in southern China is low and may decline over successive rotations. This study focuses on the effects of harvest residue management, intercropping, fertilisation and regeneration on productivity of a second-rotation plantation of Eucalyptus urophylla S.T.Blake. The first rotation produced 44 t ha(-1) of aboveground tree biomass in seven years. Of this, 87% was in the bark and stemwood removed at harvest. An additional 5.8 t ha(-1) of biomass was in the understorey and litter. Retention of residue at the site (from 1.4 to 17.5 t ha(-1)) increased tree height from 2.5 to 3.3 in at age 15 months. Applications of fertiliser increased the height at 15 months from 1.2 m (without fertiliser) to 4.1 in at the highest rate. Retaining litter alone without fertiliser had little effect on growth of planted trees. Fertiliser application to coppice trees also had little effect on growth.
