摘要
对９个不同施肥处理的连栽地杉木针叶的叶片质量和单叶面积进行了研究。结果表明，各施肥处理叶片质量均下降，含磷素的配合施肥，如氮磷钾加微量元素、磷钾配施、氮磷钾配施和氮磷配施等能提高杉木针叶的单叶面积，微量元素与氮磷钾混施的效果尤佳。同时，指出施肥能改善针叶光合作用的有效叶面积，认为有效叶面积比叶片质量、单叶面积与杉木材积生长的相关关系更为密切。
This paper is about the effects of 9 different fertilizer
treatments on coniferous leaf weight and per leaf area of Chinese firs plantation under
successive rotation.The results show that leaf weight is decreased by all fertilizers
treatments,M,PK,NPK and NP make per leaf area increased.In addition,a new index
called available leaf area for leaf physiologic characters is carried out,which is more
correlated to Chinese firs growth than above two another leaf indexes.
