摘要: 分析了澄迈县不同种植年限福橙园中土壤硒和叶片硒含量的变化。结果表明,随着种植年限的增加,土壤硒含量呈现先升高后降低再升高的趋势,与福橙叶片中硒含量的变化和硒的富集度变化趋势不一致。而福橙叶片中硒含量与叶片硒的富集度均呈现先升高后降低的趋势,变化趋势一致。种植3年的福橙园中,叶片中硒含量和叶片硒的富集度达到最大,分别为0.134 0 mg/kg和0.136 7,有利于植物对硒的吸收。但种植7年以上的福橙园中,叶片硒含量和叶片硒的富集度却很低,分别为0.038 2 mg/kg和0.036 8,不利于植物对硒的富集。

Abstract: : This study analyzed the changes of soil selenium and leaf selenium contents in Fu cheng orchards of different planting years in Chengmai county. The results showed that with the increase of planting years, the content of Se in soil increased first and then decreased, which was inconsistent with the change of Se content and Se enrichment in leaves of Fu cheng. The content of selenium in leaves of Fu cheng and selenium enrichment in leaves showed a trend of increasing first and then decreasing, and the change trend was consistent. The content of selenium in leaves and the enrichment degree of selenium in leaves of Fu cheng orchard planted for three years were 0.134 0 mg/kg and 0.136 7 respectively, which were beneficial to the absorption of selenium by plants. However, the selenium content and selenium enrichment in leaves of Fu cheng orchard planted for more than 7 years were very low, which were 0.038 2 mg/kg and 0.036 8 respectively, which was not conducive to selenium enrichment in plants.

Key words: Fu cheng, different planting years, soil selenium, leaf selenium, enrichment
