摘　　要：通过对欧洲鹅耳枥(Carpinus betulus)及其2个园艺品种(‘Frans Fontaine’和‘Lucas’)在北京、南京、靖江3地的碳素营养和矿质营养状况的研究分析,研究适宜各欧洲鹅耳枥营养积累及生长的地区及在营养积累方面占有优势的品种。结果表明,C.betulus在碳素营养积累方面占有较大的优势,C.betulus‘Frans Fontaine’的矿质元素含量最高;3地不同欧洲鹅耳枥叶片中矿质元素含量均为N>K>P,其生长均属于磷含量制约植物生长型,因此,在欧洲鹅耳枥的繁殖栽培中要注意磷肥的施用;北京地区各欧洲鹅耳枥叶片中的碳素营养及矿质营养含量均最大,3地中北京地区更适宜各欧洲鹅耳枥的营养积累。Taking Carpinus betulus and its two cultivars （C.betulus ‘Frans Fontaine’,C.betulus ‘Lucas’） as experimental materials,carbon nutrition and mineral nutrition of different cultivars of C.betulus in Beijing,Nanjing and Jingjiang were researched and analyzed to find the region which was more suitable to accumulate nutrition for different cultivars of C.betulus and the cultivar which had an advantage in nutrient accumulation.The results showed that C.betulus had an large advantage in accumulating carbon nutrition,and the highest content of mineral nutrition was in the leaves of C.betulus ‘Frans Fontaine’.The content of mineral elements in the leaves of different cultivars of C.betulus in three regions were in the order of N〉K〉P,and the growth of that was constrained by the content of P,so it is very important to apply phosphate fertilizer properly in propagation and cultivation.Beijing is the most suitable place for nutrient accumulation among the three regions because of the largest content of carbon nutrition and mineral nutrition in the leaves of different cultivars of C.betulus.
