Abstract: It is necessary to establish the cutting orchard of Toona ciliata for solving the problems of insufficient cuttings and low propagation coefficient during cutting process. Taking clones of T. ciliata propagated by our project group as the experimental material, systematic study was carried out on the relationship between clone characteristics, planting intensity, heading height of clone plant, pruning intensity and total buds number of twigs by field trials. The results showed that: the total buds of twigs of T. ciliata clones depended on clones’characters, planting density, stem height, and pruning intensity. To establish clones cutting orchard, the optimum density was 1.0 m×2.0 m, and stem height was 80 cm, at the same time, pruning the branches by one-third or half could have good effect of increasing production on semi-lignified branches.
