试验通过根部淋施和叶面喷施不同浓度硒肥两种方法,研究红衣花生富集硒元素的差异,以期为生产不同硒含量红衣花生提供依据。结果发现:在富硒土壤上种植红衣花生,红衣花生对土壤中的硒富集能力较强,不施用含硒微肥时,花生仁硒含量也达到富硒农产品标准;在红衣花生结荚期施用含硒微肥,叶面喷施和根部淋施两种方法对提高红衣花生硒含量效果都达到极显著水平,叶面喷施效果比根部淋施效果好。
Two methods were applied to study the enrichment of selenium in red peanuts by means of root leaching and foliar application of different concentrations of selenium fertilizer in order to provide basis for the production of red peanuts with different selenium content. The results showed that planting red peanuts and red peanuts on selenium-rich soils had a strong ability of enriching selenium in the soil. When the selenium-free trace fertilizers were not applied, the selenium content of peanut kernels reached the standard of selenium-enriched agricultural products. At the podding stage, the application of selenium-containing trace fertilizers, foliar application and root leaching increased the selenium content of red peanuts very significantly, and the foliar spraying effect was better than the root leaching.
