含硒植物营养剂对桃和梨吸收铅、镉、汞的拮抗作用

摘要

The effects of containing selenium plant nutrition agent on beneficial minerals element selenium, heavy metal element of lead, cadmium, mercury of peach, hog fruits were studied by field experiment. Results show that: compared with controlled peaches and pears, selenium content in experimented peaches and pears increased 1 132.7% and) 542.9%, while the content of lead, cadmium, mercury in peaches reduced 83.5.%, 65.5%, 23.9% respectively, and those in pears reduced 30.0%, 23.9%, 6.3% respectively.%采用田间试验,研究含硒植物营养剂对水蜜桃和沙梨果实中有益矿物质元素硒和重金属元素铅、镉、汞的影响.结果表明,植物营养剂处理水蜜桃果实中有益矿物质元素硒含量比对照增加1132.7％,重金属元素铅、镉、汞含量比对照分别减少了 83.5％,65.5％,23.9％:植物营养剂处理沙梨果实中有益矿物质元素硒含最比对照增加了 1542.9％,重金属元素铅、镉、汞含量比对照分别减少了30.0％,23.9％,6.3％.
