太行山大枣品质与生态地质地球化学环境的相关性分析

THE CORRELATION BETWEEN THE QUALITY OF CHINESE DATES AND THE ECOLOGICAL GEOLOGICAL-GEOCHEMICAL ENVIRONMENTS OF THE TAIHANG MOUNTAINS

通过对太行山中段采集的大枣和土壤样品的分析和对比,论述了影响太行山地区优质大枣品质的各项因素,指出了影响大枣生长的构造、岩石、土壤、地球化学异常,气候、地下水、地形等多项因素的作用和主次关系,即地质构造控制片麻岩的分布,优质大枣与片麻岩分布相关;高程500 m以下是太行山山区优质大枣适生地带,高程低于200 m、片麻岩区、沟谷地带、阳坡条件下的大枣品质更好。

Based on the analysis and comparison of Chinese date and soil samples collected in the central part of the Taihang Mountains,this paper deals with the factors affecting the quality of high-grade Chinese dates in Taihang Mountain area,and points out the primary and secondary relationships of various factors affecting the growth of Chinese dates,such as structure,rock,soil,geochemical anomaly,climate,underground water and landform.Geological structures control the distribution of gneiss,which,in turn,is related to the growth of high-quality Chinese dates;areas with elevation lower than 500 m are suitable for the growth of high-grade Chinese dates,and the quality of Chinese dates is even better in areas characterized by elevation of lower than 200 m and distribution of gneisses,gullies,valleys and sunny slopes.
