The influences of using several dosages of Yuetian soil conditioner on the output, heavy metal concentration of areca taro and soil basic fertility characteristics were studied by field plot experiment. Outcomes indicated that the output of areca taro enhanced by 6.2%∼12.8%, As concentration decreased by 28.9%∼40.0%, Hg concentration decreased by 28.6%∼50.0%, soil pH value enhanced by 4.0%∼34.9%, exchangeable acid decreased by 10.5%∼95.2%, available phosphorus decreased by 36.4%∼54.6%, and the concentration of organic matter, hydrolytic nitrogen and available K was different, but the concentration of Pb, Cd and Cr enhanced, and the concentration of Hg and As was different.
