Abstract

The invention discloses a method for promoting sprouts of a eucalyptus through girdling. The method includes the steps of (1) girdling season selection, (2) girdling cut position selection, (3) girdling cut character control, (4) girdling cut width control, (5) girdling cut treatment and (6) girdled stock plant management. Through the method, optimized vegetative propagation (cuttage or tissue culture) sprout strips are obtained under the premise that a stock plant is not hurt. By the adoption of the technical measure for promoting the sprouts of the eucalyptus through girdling, the sprouts only grow below cuts of the eucalyptus stock plant, calluses are formed rapidly after girdling, healing is conducted automatically, the lower the girdling cuts are, the higher the optimization degree of the sprout strips is, the required optimized vegetative propagation sprout strips can be harvested in about two mouths, and the girdling cuts of the stock plant are healed completely in about three mouths, and the method is simple, efficient and high in practicability.
