Abstract: By studying the allocation pattern of non-structural carbon and biomass of spring shoots and new bamboos after strip clear-cutting, we explored the growth status, adaptation strategy, and recovery potential of bamboos after strip clearcutting in Moso bamboo (Phyllostachys edulis) forest. The aboveground biomass allocation of new bamboos and the content of non-structural carbohydrates (NSC) of spring shoots and new bamboos with three diameter classes (large, medium, and small) in Moso bamboo forest after strip clear-cutting were measured, with selective cutting plots as control. The results showed that biomass proportion of aboveground organs of new bamboos in CK and the new large-diameter bamboo in strip clear-cutting plots were in the order of stem (more than 70%), branch (10%-20%) and leaf (less than 10%). The biomass allocation of small-diameter bamboo followed as leaf (45.1%), stem (32.9%), and branch (22%). The NSC content of spring bamboo shoots in later growing stage in strip clear-cutting plots was lower than that in CK. Moreover, the NSC contents in various organs of new bamboos across three diameter classes in strip clear-cutting plots were lower than those in CK. The allocation of NSC was followed as leaf, rhizome, branch, stem, underground trunk, and root on underground trunk. After strip clearcutting, aboveground biomass allocation of new bamboos in strip clear-cutting plots was different from that in CK, with lower NSC content. However, biomass proportion of branch and leaf and NSC content in the small-diameter bamboo were higher, indicating self-adaptation strategy of Moso bamboo after high-intensity harvest.
