STUDIES ON MIXED FUELWOOD OF EUCALYPTUS I.A PRELIMINARY REPORT ON DIFFERENT MIXED SPACING AND DIFFERENT PROPORTION

Eucalyptus leizhou No.1,E.cxserta and Acacia auriculiformis,A.mearnsii were planted in a 1:1 and 2:1 mixture by rows with a spacing of 1×1.5 mat one location.Through 3 years observation,mixed stand of E.leizhou No.1,and A.auriculiformis with an average above ground biomass of 92.6t/ha was very successful.The production in 1:1 mixture was much more than those in 2:1 mixture and the pure eucalyptus stands.A.auriculiformis was cut at a stump height of 60cm and it sprouted satisfactorily after harvest under eucalyptus.Mixed spacing experiment of E.exserta and A.auriculiformis in 1:1 mixture by rows was carried out at another location.The experimental results 3how that the best mixed spacing is 1×1×1m.
