The Relationship Between Jujube Quality And Geological Geochemical Characteristics In Zanhuang,Hebei

Jujube is the advantage of the fruits in China, is one of the famous traditional varieties in hebei province. Jujube quality is excellent, has high nutritional value, the origin of geological and geochemical characteristics is an important factor that influences the quality of jujube. To this end,this thesis Zan Huang jujube producing area in hebei province as the study area,In fully collecting Zan Huang natural economic background of the research region and jujube producing elements on the basis of geochemical data,Collected specimens surface soil samples and big jujube, and then applies the method of mathematical statistics,Analysis of geochemical characteristics of stream sediments in the study area,soil geochemical characteristics, geochemical elements in soil total amount corresponding elements,effective state of relations,And combination of elements content in jujube in the study area and the distribution features of the quality indicators,to further study the effect of soil geochemistry of jujube quality.Again on the basis of the comprehensive other geological and geochemical factors, further expounds the geological and geochemical features in the study area’s influence on the quality of jujube. The results showed that:1、Soil study area CaO、K₂O3、MgO、Na₂O、TFe₂O₃、Al₂O₃、Cr、Cu、Mn、P、Ni element is generally higher than the average national average;Mo、B element is lower than or close to the national average.2、B, Mo elements in soil and Vc content in fresh jujube has significantly positive correlation;N、P、S、Vc content in zinc element and fresh jujube showed extremely significant negative correlation.3、Fe₂O₃、 Mn、 N and P in soil and the content of soluble protein in fresh jujube has significantly positive correlation.4、Parent rock types and landform characteristics the impact on the quality of jujube is significant.5、Among all kinds of ecological geological and geochemical factors, rock type is the dominant factor.
