对树木叶片矿质养分的分析可鉴别无性系。采自不同立地、不同树龄的杉木叶片经分析矿质养分含量。结果表明:同一地区相同年龄无性系间叶营养元素含量差异达显著或极显著水平。相同年龄的不同无性系或不同年龄的相同无性系,其N:P:K比值有明显差异。在N:P:K比值中,P变化相对较小。Cu与N、P、K、Ca、Mg呈显著或极显著正相关,K与Zn呈显著负相关。K与杉木生长(高、胸径)呈极显著正相关,P、Mg与生长呈极显著负相关。 Analysis of mineral nutrients in tree leaves identifies clones. Mining from different sites, different ages of the fir leaf analyzed by mineral nutrient content. The results showed that there was significant or extremely significant difference in leaf nutrient content among clones of the same age at the same age. Different clones of the same age or the same age of the same clones, the N: P: K ratio significantly different. In the N: P: K ratio, P changes are relatively small. There was a significant or very significant positive correlation between Cu and N, P, K, Ca, Mg, while K was negatively correlated with Zn. There was a significant positive correlation between K and Chinese fir growth (height and DBH). P and Mg had a very significant negative correlation with growth.
