| 摘 要： | 采用土培盆栽试验研究了贫硒土壤中添加富硒奶牛粪和富硒水稻秸秆生物炭2种不同富硒有机肥对玉米硒含量及贫硒土壤硒含量的影响。研究结果表明:添加富硒奶牛粪处理中的玉米对硒的吸收富集效果优于添加富硒水稻秸秆生物炭的处理,且植株根部吸收硒后更易于转运到地上部,硒在其体内的迁移率高。从2种有机肥的添加量来看,基施25 t·hm-2富硒奶牛粪以及40 t·hm-2富硒水稻秸秆生物炭对玉米生长有更好的促进作用,玉米植株内的硒含量及生长状况均优于其他处理。与此同时,富硒奶牛粪和富硒水稻秸秆的添加均能显著提高土壤中全硒的含量,且均随着富硒有机肥施用量的增加而增加,与富硒有机肥施用量呈显著正相关。

| Abstract: | The effect of two Se-enriched organic fertilizers (cow dung and rice straw biochar) on selenium accumulation of corn growing in selenium deficient soil was studied with pot experiment. The results showed that corn accumulated more selenium and the selenium was much easier to convert from root to shoot in the corn plant with the application of Se-enriched cow dung than Se-enriched rice straw biochar. With the application of more organic fertilizer such as 25 t·hm-2 Se-enriched cow dung or 40 t·hm-2 Se-enriched rice straw biochar, the accumulation of selenium and growth status of corn were getting better than the other treatments. At the same time, as the application amount of Se-enriched organic fertilizers (cow dung and rice straw biochar) increased, the total selenium content in the soil also increased, which positively correlated with each other. |
