摘要
通过对粤东凤凰茶区10个茶园的茶叶和土壤氟含量状况进行调查,结果表明,粤东凤凰茶区茶园茶叶全氟含量在66.25~412.10 mg kg-1的范围内,平均值为238.2 mg kg-1;土壤全氟含量介于400~450 mg kg-1之间,基本低于全国氟的土壤背景值(453 mg kg-1);土壤水溶性氟平均含量介于0.20~0.50 mg kg-1之间。茶叶全氟含量与土壤水溶性氟有极显著的相关性,但与土壤全氟没有相关性;土壤水溶性氟含量与土壤pH值、交换性阳离子Ca2+、Mg2+、Na+、K+含量呈非常显著的正相关性,与交换性阳离子Mn2+和有机质含量呈非常显著的负相关性。
The F content in tea leaves,and total soil F and soil soluble F in ten FengHuang Tea Gardens of East Guangdong Province were determined.The results showed that the F contents in tea leaves were between 66.25-412.10 mg kg-1,with average of 238.2 mg kg-1.The content of total soil F was 400-450 mg kg-1,lower than the soil F background in the whole country(453 mg kg-1).The soil soluble F was between 0.20-0.50 mg kg-1.The high positive correlation was found between the F content in tea leaves and water soluble F.In addition,we found that the water soluble F content presented high positive correlation to the soil pH,and the contents fo exchangeable iron Ca,Mg,K and Na.On the contrary,the highly negative correlation was observed between the water soluble F and the contents of organic matter and the exchangeable Mn.
