【摘要】 在杉木地理种源矿质分析的基础上，研究了地理种源矿质养分（氮、钾、磷、钠、铁等元素） 的变异规律，研究结果表明：不同杉木种源针叶灰分中钾、铁和磷的百分含量达到了极显著，显著差异，其中钾含量与高生长呈极显著正相关，即生长快的种源钾含量高于生长慢的种源更多还原

【Abstract】 Based on the analyses of the mineral nutrients from chinese fir geographical provenance,the variant regularities of the mineral nutrients the elements such as N,K,P,Na,Fe-from the geographical provenance were studied in the paper.The result shows:there are extreme significant and significant differences among the potassium.irom and phosphorus percentages in the ash of coniferous leaves from different chinese fir provenance,in which there are positive correlative relations between the potassium percentage and the growth of the tree height Namely,the potassium content of the provenance that grows faste is higher than the one that grows slowly.更多还原
