Abstract：Five sympodial bamboo species with medium size that have been widely applied, i.e., Neosinocalamus affinis, Bambusa ventricosa, B. intermedia, Chimonocalamus delicatus, B. pervariabilis×Dendrocalamopsis daii, were selected to study their growth law during the shooting stage, with the expectation to provide scientific basis to their cultivation, extension and application. The results showed that the peak shooting period of the 5 bamboo species appeared between June and August, and their shooting time lasted 94-290 d. Among them, Ch. delicatus had the longest shooting time while N. affinis the shortest. The rate of shoot degradation for the 5 species was 12%-21%, and the shoot degradation rate of B. pervariabilis×D. daii was the highest while Ch. delicatus had the lowest rate. The annual mean temperature and rainfall at the planting area had the direct influences on the shoot growth, that is, the higher the annual mean temperature and rainfall were, the lower the rate of shoot degradation would be, and the longer the shooting period, the bigger the shoots. Fertilization could facilitate the shoot growth during the shooting stage, and different fertilizers had the different facilitating performance, among which urea had the best performance, followed by N-P-K compound fertilizer, and the calcium superphosphate (SSP) had little effects for shoot growth.
