冰冻灾害后，采取施用复合肥、有机肥、竹类专用肥及清林4种不同复林措施，对孝顺竹竹林的发笋、退笋、地径及高生长的变化进行了连续观测和数据分析。试验表明：孝顺竹发笋期为6月中旬至8月下旬，历时2个多月，发笋量呈偏正态分布，施肥可提高提前发笋量且提前发笋时间相对集中；发笋盛期和末期退笋数明显增加，退笋多发生于高度30 cm以下，成竹率随着退笋率的升高而降低；地径生长主要集中在10 d以内，竹笋-幼竹高生长呈“S”形曲线；处理样地中的发笋量、成竹率、地径、高度指标均比对照样地中的高。各复林措施对冰冻灾害后孝顺竹竹林的恢复起到了良好的促进作用，其中施用有机肥的效果最好。

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.
