在柑橘产区大范围采集田间叶片、土壤样品,并对样品的化学分析数据进行相关分析,筛查柑橘P吸收的主要障碍因子,研究Hg等重金属污染对柑橘P吸收的影响.经2 a对3个柑橘品种250组数据进行筛查,验证柑橘叶片Hg污染为影响植株P吸收的主要因子,叶片Hg含量大多高于土壤Hg含量,它们之间的相关性不显著;在抽查的12份含Cu杀菌剂中检测出6份Hg含量≥0. 5 mg·kg~(-1),最高达15. 1 mg·kg~(-1),表明杀菌剂是柑橘生产中Hg的污染源之一.

Main barrier factors in P absorption by citrus plants were screened by collecting leaves and soil samples in the large area of citrus-producing area, and making correlation analysis on data of chemical analysis. It was validated that pollution from Hg in leaf was the main influencing factors of P absorption by citrus plants, by screening 250 data of 3 citrus varieties for 2 years. Leaf Hg content was higher than soil Hg content and the correlation between them was not significant. In randomly checked 12 fungicides, Cu contents in 6 fungicides were over 0. 5 mg·kg~(-1), the highest content was 15. 1 mg·kg~(-1), As a result, fungicide is Hg pollution resource in citrus orchard.
