Abstract:Phyllostachys pubescens is a tree-like giant bamboo with important economic values. Based on a fertilization experiment designed in a way of completely randomized blocks, we investigated influences of different dosage and way of fertilization on the Clonal growth of new bamboo shoots in P. pubescens. It was shown that the mean number of bamboo shoots emerging and surviving per plot might be significantly increased up to more than three times by the fetilization, although the individual size was not significantly improved. The mean survival rates of bamboo shoots per plot were almost the same in all treatments. The bamboo may be able to selectively place more new shoots in the favourable sites than in unfavourable sites when it encountered a heterogeneous environment. On the other hand, there existed clear evidence that physiological integration occurred between new shoots developing in the poor sites and older shoots established in the good sites. Using plots of 9m × 9m, fertilization showed significant effects. Therefore, it is not necessary to use plots of 1mu (667m2) which were traditionally used. It is more profitable to fertilize patchily than evenly for increasing production.
