摘要
以新疆南疆18个灰枣产区的完熟期果实为试材,探讨各产区果实品质指标的差异性,并对果实品质进行综合评价,结合前人研究结果,明确新疆南疆灰枣优生区,旨在为新疆南疆灰枣产业提质增效、科学发展提供参考。结果显示:灰枣各品质指标在不同产区间存在着显著性差异,而各品质之间存在着密切相关性。因子分析提取了4个公因子,其累计贡献率为82.058%,以各因子贡献率为权重计算各产区灰枣综合得分并排序,聚类分析将18个产区分为3类,且因子分析和聚类分析结果基本一致,塔里木盆地东南部地区灰枣果实综合品质优于西北部地区。与根据新疆气象资料分析结果进行交叉分析得出,若羌、民丰、洛浦、且末4个产区不仅在气候因子方面极其适宜灰枣生长发育,而且灰枣果实的综合品质也较好,因此这4个产区为新疆南疆灰枣最佳优生区。
The mature fruits from 18 gray jujube producing regions in Southern Xinjiang were used to study the differences of fruit quality indicators in each producing regions and comprehensively evaluate the fruits.Based on the results of previous studies,the eugenic zone of gray jujube in Southern Xinjiang was clarified to provide a reference for improving the quality and efficiency of the jujube industry and scientifically developing the gray jujube industry in Southern Xinjiang.The results showed that there were significant differences in the quality indicators of gray jujube among different production regions.There was a close correlation between each quality.Four common factors were extracted by factor analysis,and their cumulative contribution rate was 82.058%.The contribution rate of each factor was used to calculate the comprehensive score of gray jujube in each producing regions and rank.The 18 producing regions were divided into 3 categories by cluster analysis.The results of factor analysis were basically the same as cluster analysis.The comprehensive fruit quality of gray jujube in the southeast of Tarim Basin was better than that in the northwest.The results of cross-analysis with previous researches showed that the four producing regions including Ruoqiang,Minfeng,Luopu,and Qiemo are not only extremely suitable for the growth and development of gray jujube in terms of climate factors,but the comprehensive quality of gray jujube fruit is better as well.It is indicating that these four producing regions are the best eugenic zones of gray jujube in Southern Xinjiang.The restructuring of the gray jujube eugenic zone in Southern Xinjiang is of guiding significance for developing the jujube industry.
