摘  要：
以福建省沙县官庄国有林场第3代杉木种子园为对象,对母树叶片、枝和土壤养分含量进行了诊断分析。结果表明:母树叶片中大量元素含量大小为N>K>Ca>Mg>P,微量元素含量大小为Mn>Fe>Zn>Cu,叶片中N/P、N/K、N/Mg、N/Ca分别为9.75、1.57、9.72、1.87;枝中大量元素含量大小为Ca>K>N>Mg>P,微量元素含量大小为Fe>Mn>Zn>Cu,枝中N/P、N/K、N/Mg、N/Ca分别为4.80、0.91、3.46、0.89;0～60 cm土层中土壤有机质含量均值为25.92 g.kg-1,大量元素含量大小为K>Mg>N>Ca>P,微量元素含量大小为Fe>Zn>Mn>Cu,0～20、20～40、40～60 cm土层中C/N比值分别为12.06、11.32、8.68。综合分析表明,N、P和Mn元素含量偏低,建议在经营过程中加以补充。

摘  要：
A study was conducted to analyze the nutrient contents of mother tree components(leaf,branch)and soil in a third generation Cunninghamia lanceolata seed orchard,which was located at the Guanzhuang National Forestry Centre,Sha County,Fujian Province.The results showed that macro-element contents in leaves decreased consistently in the following order:N>K>Ca>Mg>P,micro-elements in leaves decreased consistently in the following order:Mn>Fe>Zn>Cu.The values of N/P,N/K,N/Mg,and N/Ca in leaves were 9.75,1.57,9.72 and 1.87,respectively.Macro-element contents in branches decreased consistently in the following order:Ca >K>N>Mg>P,micro-elements contents in branches decreased consistently in the following order:Fe>Mn>Zn>Cu.The values of N/P,N/K,N/Mg,and N/Ca in branches were 4.80,0.91,3.46 and 0.89,respectively.The average value of organic matter in soil depth of 0~60 cm was 25.92 g·kg-1.Macro-element contents in soil decreased consistently in the following order:K>Mg>N>Ca>P,micro-element contents in soil decreased consistently in the following order:Fe>Zn>Mn>Cu.The values of C/N decreased along soil depth,which were 12.06,11.32 and 8.68 in the depth of 0~20,20~40 and 40~60 cm,respectively.The contents of N,P and Mn were lower than other nutrients,which should be added to the seed orchard to sustain high seed yield.
