摘　　要：本试验采用3～5株优势木对比法开展灵武长枣优树比较研究。对选定区域内的优树,测定其生长性状指标、光合基础性状指标、果实性状指标,利用主成分分析法、隶属函数分析法等方法,对其进行综合评价分析。结果表明:不同编号的灵武长枣优树的综合评价得分排序为1335>1415>2101>2017>2016>1219>1602,编号为1335的灵武长枣优树综合指标表现最佳。该研究为灵武长枣的繁殖推广及研究提供一定的参考依据。Three to five dominant species of Zizyphus jujuba cv. Lingwuchangzao were adopted for comparative study in this paper. Their growth character indexes, photosynthetic character indexes and fruit character indexes were measured in the selected area. The PCA(principle component analysis) and MFA(membership function analysis) were used for comprehensive evaluation. The results showed that the comprehensive evaluation scores of dominant species of Zizyphus jujuba cv. Lingwuchangzao with different numbers were ranked as follows: 1335>1415>2101>2017>2016>1219>1602. No.1335 dominant species of Zizyphus jujuba cv. Lingwuchangzao had the best performance. The research could provide some references for the propagation promotion and study of Zizyphus jujuba cv. Lingwuchangzao.
