不同品种油葵对土壤中镉的富集作用比较研究
Comparative Study on the Soil Cadmium Enrichment of Different Oil Sunflower Varieties
摘要
Abstract
High cadmium accumulation varieties of oil sunflower were screened in 2016.The results showed that:(1) There were differences in the cadmium amounts of different oil sunflower varieties in same cadmium contaminated land,and there were differences in the accumulated cadmium in different parts of the same variety.(2) There were obviously differences in the yields of different oil sunflower varieties under the same cadmium background.The yields of the same cultivars were not obvious at the different cadmium background.(3) The cadmium contents in the seeds were no significant in different oil sunflower cultivars and different cadmium content soils.(4) There was also no signficant difference in cadmium content oil sunflower cultivars in different cadmium content soils.(5)The transfer coefficients from straw to seed were less than 1 in all oil sunflower cultivars.The enrichment factors of the straw and seed were more than 1 of all oil sunflower cultivars,and the enrichment factors of the straw were more than that of the seed.(6) The cadmium content in the crude seed oil was very low and safe for consumer whether the oil sunflower planted in moderate cadmium contaminated soil or severe cadmium contaminated soil.关键词
