沾化冬枣产地土壤地球化学环境对冬枣品质的影响

目的]为探讨土壤的地球化学性质对冬枣品质的影响。方法]利用山东省黄河下游流域局部生态地球化学调查的基础数据,对调查区内表层土壤的地球化学环境与冬枣品质之间的相关性进行探讨。结果]区内土壤营养元素中的Cd、Ni等重金属元素对于冬枣的营养成分的影响较为明显。结论]根系土中的B、Mn、MgO、Cd、Zn、K2O等对冬枣果实中Cr、Hg元素的富集起较大作用,可通过改善施肥方法对冬枣根系吸收重金属的过程进行干预,以降低有害元素在冬枣果实中的富集。

Influence of Soil Geochemistry to the Quality of Winter Jujube in Zhanhua

Objective] The aim was to investigate the effects of soil geochemistry on the quality of winter jujube.Method]Based on the data of ecological geochemical survey in lower Yellow River Basin,the relevance of the geochemistry environment in top soils and the quality of winter jujubes was analyzed.Result]Cd,Ni and other heavy metals in the soil more obviously affected the nutrition of winter jujubes.Conclusion]B,Mn,MgO,Cd,Zn,K2O and other elements in the root soil played an important role in the enrichment of Cr and Hg of winter jujube fruit.And the absorption of heavy metals in winter jujube root could be interfered by improving fertilization method,to reduce the enrichment of harmful elements in jujube fruit.
