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.
