Abstract:
In order to clarify the effect of medium ratio and cutting time on the survival rate of summerwood cuttings of
Eucalyptus grandis,researches were conducted by randomized block experimental design. The results showed that effect of the matrix 1 was the best, the cutting survival rate was 61.78% and the season had significant effects on the survival rate of cuttage. The survival rate was the highest in spring and the lowest in summer. The survival rate in autumn was between the former two seasons.
