Abstract：This studyinvestigated theeffects of water-fertlizercouplingtreatments onphysiologicalcharacteristics of Phyllostachysedulisleaves.Principalcomponentanalysiswas employedtoscreenoptimal water-fertlizercoupling modelsfor Phylostachysedulisforests，aimingtoprovidetheoreticalfoundationsforscaledproductionandficientcultivatioofPhyllostachys edulis.The study was conducted ina Phylostachys edulis forestatJinju Village，Xi’nan Town，Zhangping City， FujianProvince，employingasplit-plotexperimentaldesignwithninetreatments.Threeirigationlevelswereestablishedbased on soil moisture content ： 85%±5% of field capacity （W1），65 1%±5% of field capacity（W2）， 50%±5% of field capacity（W3）.Concurrently，threefertilizationlevels were applied： 1.25×105kg/hm2 compound fertilizer （F1）， 6.25×104kg/hm2 compound fertilizer（F2）， 3.13×104kg/hm2 compound fertilizer（F3）.The nitrogen， phosphorus，and potassium ratio in the compound fertilizer
