【摘要】 采用土壤拌施亚硒酸钠的方法,研究不同硒肥施入量对黑花生的产量和硒元素含量的影响.结果表明:随着土壤施硒量的增加,黑花生的产量先增加后减少,且黑花生的硒含量呈递增趋势.当土壤施硒量为2mg/kg时,黑花生的硒含量达到人类食用的最高标准0.3mg/kg.当土壤施硒量为1.9mg/kg时,黑花生的产量达到最高,为4 354.17kg/hm2,此时,黑花生的硒含量为0.28mg/kg.更多还原

【Abstract】 Yield and selenium content of black peanut under the different selenium fertilization were researched by mixing soil with Na2SeO3.The results showed that with the increasing of selenium fertilization amount,the yield of black peanut first increased and then decreased,while the selenium content showed an increasing tendency,but when the selenium fertilization amount was higher than 2 mg/kg,selenium content of black peanut exceeded the highest standards for human(0.3 mg/kg).When the selenium fertilzaton was 1.9 mg/kg,the yield of black peanut reached the highest 4 354.17 kg/hm2 and the selenium content of black peanut was 0.28 mg/kg.更多还原
