福建茶园土壤Zn含量及其影响因素
Zn content and related factors of tea garden soil in Fujian
摘要
Abstract
Based on the measurement of 62 soil samples in tea garden in Fujian, related factors in Zn content and its effectiveness were researched using path analysis. Results indicated that the average content of total Zn was 28.85 mg-kg-1, its median content was 58.80 mg-kg-1, its coefficient of variation was 45.16%; The content of effective Zn ranged from 0.11 to 15.04 mg-kg-1, its average content was 2.95 mg-kg-1, its median content was 1.47 mg-kg-1, its coefficient of variation was 123.14%; Zn activation rate ranged from 0.26% to 24.53%, its average content was 5.02%, its median content was 2.72%, its coefficient of variation was 114.87%. Correlation analysis revealed that there was highly positively correlative between total Zn content and pH value, so was among effective Zn, organic matter and total nitrogen. However, Zn activation rate was highly negatively correlated with pH, highly positively with organic matter, total nitrogen, respectively. Path analysis found that pH significantly directly influenced total Zn, and total nitrogen has significantly directly did effective Zn, Zn activation rate whereas pH and total P negatively influenced effective Zn, Zn activation rate.关键词
