Abstract:
Taking ‘Manshanhong’ radish as test material,the effects of spraying alginic acid at different multiples on the growth and cadmium accumulation of radish were studied through the method of pot experiment,in order to provide reference for the production of safe vegetables in cadmium contaminated soil.The results showed that spraying different concentrations of alginic acid increased the root,tuber and leaf biomasses of radish to some extent compared with the control,and with the increase of alginic acid concentrations,the biomass of each organ increased.Among them,600 fold dilution of alginic acid significant increased the root,tuber and leaf biomasses of radish by 98.59%,16.95% and 39.13%,respectively,compared with the control.Alginic acid treatment also increased the photosynthetic pigments (chlorophyll a,chlorophyll b,total chlorophyll and carotenoid) content and the antioxidant enzymes (SOD,POD and CAT) activity of radish to some extent.In terms of cadmium content,compared with the control,600 and 900 fold dilutions alginic acid treatments significantly promoted the cadmium absorption of radish roots,600 fold dilution alginic acid significantly increased the cadmium content in tuber,and 600,900 and 1 200 fold dilutions alginic acid treatments all significantly increased the cadmium content in leaves and edible parts.Therefore,alginic acid treatment could promote the growth of radish,but also could promote the cadmium absorption of radish,which was not suitable for radish cultivation in cadmium-contaminated soil.
