摘要
研究土施粉煤灰对水稻和小麦含硒量的影响，结果表明，土施粉煤灰可以显著提高水稻和小麦的含硒量，一次性施用粉煤灰２０ｇ／ｋｇ土（合每亩３０００ｋｇ）时，水稻精米和小麦籽粒含硒量均达到０．５ｍｇ／ｋｇ以上，但不超过１．０ｍｇ／ｋｇ，一次性施用粉煤灰不超过４０ｇ／ｋｇ二（合每亩６０００ｋｇ）时，水稻和小麦的产量分别增加１．０％～１７．１％和６５％～１４．５％，且水稻精米和小麦籽粒中Ｃｄ、Ｃｒ、Ｐｂ、Ａｓ等重金属的含量均未超过食品卫生标准。
Pot experiments were conducted to study the effects of fly ash on the selenium contents of rice and wheat.The results indicates that using fly ash as Selenium fertilization can raise the selenium contents of rice and wheat.The Selenium contents in the kernel of rice and wheat reached 0.5～1.0mg/kg when soil application of fly ash was 20g/kg. Theyeild of rice and wheat increased,and the heavy metal contents in th kernel of rice ancl wheat didn' t exceed hygienical standards for food when soil application of fly ash less than 40g/kg.
