Study on the Forestation Effects of Different Mixed Planting Modes of Eucalyptus and Acacia Melanoxylon
A series of experiments were designed and implemented to study the mixed planting patterns of Euca-lyptus and Acacia melanoxylon with different mixed gradients.The growth performance of Eucalyptus and Acacia melanoxylon under different mixed gradients is systematically analyzed.The experimental results show that mod-erate mixed gradients can promote the symbiotic relationship between Eucalyptus and Acacia melanoxylon,and improve the biodiversity and ecosystem stability of mixed.Meanwhile,the analysis found that different mixed gradients have a significant impact on the survival rate of Eucalyptus.The mixing ratio of Eucalyptus and Acacia melanoxylon was 70:40,which showed the best comprehensive effect.The different mixed planting patterns have little effect on the average height and average diameter at breast height of Eucalyptus or Acacia melanoxylon,in-dicating that under different mixed ratios,the growth level of the two mainly depends on the species itself.This provides a reference for the selection of mixed species and the optimization of mixed forest management in the fu-ture.
