Abstract: |
E. grandis×E. urophlla is the most quickly-growth and highest yield in Eucalyptus. Under the same condition and the equal number of trees in a unit area (1665 N/hm2). There were significent differences in growth among the four treatments of plantation spacing. The trees with the space of 1m×6m 3.5 years after plantation had an average height of 13.72 m and average diameter at breast height of 10.14 cm, growing stores was 68.76 m3/hm2. The growth is in the first place. |
