摘　　要：对红锥(Castanopsis hystrix)2.5 a生幼苗进行施肥试验,测定和计算其叶形态功能性状单叶鲜质量、单叶干质量、叶长、叶宽、叶长宽比、单叶面积、比叶面积及水分功能性状叶相对含水率、干物质含量,并计算不同叶功能性状间的相关性,结果表明:施肥能够显著促进红锥幼苗叶片形态生长,增加叶片光截获能力;施肥能对红锥幼苗叶水分功能性状产生显著影响,干物质含量显著减少、相对含水率显著增加;施肥驱动不同功能性状间协同变化,多数叶功能性状间存在显著的相关性。The leaf morphology functional traits such as leaf fresh weight,single leaf dry weight,leaf length,leaf width,leaf length to width ratio,single leaf area,specific leaf area and leaf water functional traits,leaf dry matter content and relative water content of 2.5 a Castanopsis hystrix seedlings were determined,and the correlations between different leaf functional traits were calculated.The results as follows:Fertilization can significantly promote leaf morphological growth and increase leaf light interception ability.Fertilization can significantly affect the leaf water functional traits,the dry matter content is significantly reduced,and the relative water content is significantly increased.Fertilization drives synergistic changes between different functional traits,and there is a significant correlation between most leaf functional traits.
