Abstract: 福建柏幼林对肥料反应敏感,施肥后树高生长增益16.19 %~37.41%,胸径增益16.35%~38.99%,肥效指数达到1.57~2.65;根的生物量增加了49.2%~136.8%,茎的生物量增加了56.6%~163.2%,枝的生物量增加了42.8%~115.6%,叶的生物量增加了30.3%~76.8%,全树生物量增加了44.3%~121.8%;叶绿素a含量增加了7.5%~179.9%,叶绿素b含量增加了4.7%~120.8%,叶绿素a+b含量增加6.7%~162.5%.施肥效果最佳的处理是N100P200K50、N100P100和P200,南方地区林地土壤缺磷,福建柏幼林施肥应以施磷肥为主,幼林前期施肥量以200 g*株-1为佳,N对叶绿素的合成起主导作用,配合施N肥对促进生长、干物质积累、叶绿素含量提高效果更佳;南方地区比较富K,因此不必施K肥.
