After the freezing disaster, four different measures including cleaning forestland, fertilizing compound fertilizer or organic fertilizer or special bamboo fertilizer were taken for speeding up the rejuvenation of Bambusa multiplex. By surveying quantity of shoots and degraded shoots, ground diameter, rhythm of height growth continuously and statistical analysis, the conclusions were drawn as follows: the shooting period lasted for more than two months from the middle of June to late August and showed skewed normal distribution. Fertilizing can increase quantity of shoots and make shooting time advance and relatively concentrate. Quantity of degraded shoots increased in flourishing stage and telophase. Their height degradation was always below 30 cm. The rate of adult bamboo reduces along with the mortality increases. Growth of ground diameter mostly concentrated in ten days and height growth showed a curve of S shape. Indicators of treated plots, such as quantity of shoots, rate of adult bamboo, ground diameter and height, are all higher than control. Four rejuvenation measures which had been taken on B. multiplex after the disaster played a good role and using organic fertilizer did the best.
