Abstract:
Taking soil samples from new and old apple orchards in Longdong with different tree ages,years,and soil layers as test materials,the effects of eight pollution elements,Cd,Hg,As,Pb,Cr,Cu,Ni and Zn on the basic physical and chemical properties of soil,orchard planting parameters,and leaf nutrient content were studied by using correlation analysis method,in order to provide reference for achieving green,pollution-free,and healthy fruits.The results showed that,1) eight heavy metal pollution elements were detected in the tested orchard,and the average content of other heavy metals exceeded the background value of soil element A in China except Hg,and the average value of Cd was 1.86 times of the background value.However,the contents of eight heavy metals did not exceed the screening value of soil environmental quality.2) Except for Cr,the content of other elements in 0-20 cm soil layer was higher than that in 20-40 cm soil layer.3)There was a significant positive correlation between Cd content and tree age.The Cd content of orchards aged 1-7 years and 8-14 years were significantly lower than that of 21-25 years and 26-30 years.More than half of Hg and Cd contents were significantly affected by soil physical and chemical properties.4) The content of Hg was most affected by the basic physical and chemical properties of soil.And Cd,As,and Cu were significantly correlated with more than half of the basic physical and chemical properties of soil.5)The content of heavy metals in soil had no significant effect on the contents of N,P and Ca in leaves;Cd,Hg,As and Ni had significant positive effects on K content,while Pb had significant negative effects on K content.
