- 摘要:
- 采用盆栽试验，研究了施用不同改良剂—骨粉、纳米羟基磷、粉煤灰及其两两组合对镉、铅污染土壤中塌地乌叶绿素及维生素C含量及品质的影响。结果表明：施入改良剂后，塌地乌叶片叶绿素含量和植株内维生素C含量均不同程度增加，硝酸盐和可溶性糖含量降低，叶绿素a/b值降低（除单施纳米羟基磷灰石）。因此，添加改良剂可提高镉、铅污染土壤中塌地乌的品质。
- Abstract:
- A pot experiment was carried out,the effects of three different kinds of amendments (bone mill，nano hydroxyapatite and bottom ash) and their two combinations on the chlorophyll content，vitamin C content and other qualities of wuta-tsai planted in Cd，Pb contaminated soil were studied.The results showed that the chlorophyll and vitamin C content increased in various degrees after amendments application，while the content of soluble sugar and nitrates decreased.The chlorophyll a/b value decreased under all treatments except treatment of applicated nano hydroxyapatite.Therefore，add amendments to the Cd，Pb polluted soil could improve the quality of wuta-tsai.
