摘　　要：对闽北马尾松二代种子园母树针叶和球果的营养元素含量进行测定,分析营养元素在母树针叶、球果中的分布特性,根据马尾松二代种子园母树的高、中、低不同产量及其针叶和球果养分含量的差异,初步探讨母树营养元素的适宜浓度范围。结果表明,马尾松种子园母树需求量较大的营养元素主要是钾、氮、钙、磷,针叶的养分含量分布特点为K> N> P> Ca> Mg> B> Mo,球果养分含量分布特点为K> N> Ca> P> Mg> B> Mo;马尾松二代种子园母树针叶的营养元素适宜浓度范围为N(7. 898～11. 831 g/kg),P(2. 798～4. 473 g/kg),K(12. 673～15. 010 g/kg),Ca(0. 945～2. 982 g/kg),Mg(0. 739～1. 573 g/kg),B(11. 226～45. 799 mg/kg),Mo(0. 161～0. 923 mg/kg)。This paper determined the nutrient elements in needles leaves and cones of seed trees in second generation seed orchard of Pinus massoniana ,analyzed their distribution characteristics and preliminarily discussed the suitable concentration range of nutrient elements according to the high, medium and low yield of seed trees and the differences of nutrient content in needles leaves and cones. The results showed that potassium,nitrogen,calcium and phosphorus were the main nutrient elements of Pinus massoniana seed orchard,each element content in needle leaves was followed as K >N >P >Ca >Mg >B >Mo,nutrient content in cones followed as K >N >Ca >P >Mg >B >Mo. The appropriate concentrations of nutrient content in needles leaves were N(7.898~11.831 g/kg),P(2.798~4.473 g/kg), K(12.673~15.010 g/kg),Ca(0.945~2.982 g/kg),Mg(0.739~1.573 g/kg),B(11.226~45.799 mg/kg),Mo(0.161~0.923 mg/kg).
